Legendary Resistance:

Legendary creatures have the ability to resist magical effects. They automatically succeed on saving throws against spells and other magical effects a certain number of times per day, making them more resilient to magic.

Legendary Actions:

Legendary creatures can take special actions outside of their regular turn. These actions allow them to exert their power and influence over the battlefield, giving them an advantage in combat. Legendary actions often involve powerful attacks, area of effect spells, or unique abilities.

Lair Actions:

Some legendary creatures have lairs that are infused with their power. While within their lair, these creatures can take lair actions, which are triggered at certain initiative counts during combat. Lair actions often affect the environment, create hazards, or provide additional support to the legendary creature.

Legendary Presence:

Legendary Mobility:

The creature possesses exceptional speed or movement abilities, allowing it to traverse the battlefield quickly and strike with precision.

Shapechanger:

This unique ability allows the creature to harness the essence of other monsters, transforming itself into a fearsome variety of beings. Once per day, the legendary creature can choose to transform into any creature it has encountered, studied, or assimilated the traits of, as long as the chosen creature's CR is equal to or lower than the legendary creature's own CR.

During the transformation, the legendary creature gains all the abilities, attacks, and features of the chosen form, including any resistances or immunities. Its physical attributes, such as size, movement speed, and natural weaponry, also change accordingly. The transformation lasts for a duration determined by the legendary creature's Hit Dice or a predetermined number of rounds.

While transformed, the legendary creature retains its legendary actions, lair actions, and any other innate abilities specific to it, effectively combining its own legendary traits with those of the chosen form. The creature's legendary actions may be adapted to complement its new form, granting it unique attacks and maneuvers.

This ability not only enhances the creature's versatility in combat but also creates a sense of mystery and unpredictability for the players, as they face a legendary adversary that can seamlessly shift between forms, making each encounter with the creature an entirely different challenge.

Conduit:

This formidable ability grants the monster the power to summon additional monsters or allies to its aid, turning a one-on-one encounter into a chaotic battle. Once per day, the legendary creature can invoke this ability to summon a group of creatures or a single powerful ally to fight alongside it.

The specific creatures summoned or the type of ally brought forth depend on the legendary creature's nature, its associations, or its thematic background. For instance, a demonic entity may summon a horde of lesser demons, a dragon might call upon wyvern allies, or a necromancer could raise an undead army.

The summoned creatures or allies act on the legendary creature's initiative count and obey its commands. The number, type, and power of the summoned creatures are usually determined by the legendary creature's Hit Dice or a predefined table. The summoned allies remain for a limited duration, such as a predetermined number of rounds, until their hit points are depleted, or until the legendary creature is defeated.

This ability adds another layer of complexity to the encounter, as players must not only face the legendary creature but also deal with the additional threats it has brought into the battle. The summoning of allies may vary from one encounter to another, keeping players on their toes and ensuring that each battle with the legendary creature remains distinct and challenging.

Reality Warping:

This extraordinary ability grants the legendary creature the power to manipulate and alter the environment to its advantage. Once per day, the creature can unleash its reality-warping capabilities, reshaping the battlefield to suit its needs and hinder its foes.

With this ability, the legendary creature can perform a variety of environmental manipulations, such as:

When the legendary creature's hit points drop below a certain threshold (e.g., 25% of its maximum hit points), it unleashes its Last Stand ability, tapping into its inner reserves of power to ensure its survival and make a final, desperate push to defeat its foes.

Depending on the creature's nature and abilities, the Last Stand can manifest in various ways:

Desperate Fury: The legendary creature gains advantage on all attack rolls and deals double damage with its attacks while its hit points are below the threshold. Its strikes become more precise, and every blow is fueled by the sheer determination to take down its opponents before succumbing to defeat.

Resilient Resurgence: The legendary creature gains resistance to all damage types while its hit points are below the threshold. It seems to draw strength from the brink of death, shrugging off blows that would fell lesser creatures, and demonstrating an unwavering resolve to stay in the fight.

Lethal Recklessness: The legendary creature gains advantage on all saving throws while its hit points are below the threshold. Fueled by the awareness of its own mortality, it becomes more agile and nimble, evading deadly effects with uncanny precision.

Death's Embrace: When reduced to 0 hit points, the legendary creature makes one final, explosive attack against a target of its choosing before it falls. This attack is made with advantage, and if successful, it deals massive damage, often leading to the creature's foes sharing its fate in the afterlife.

The Last Stand ability adds an element of surprise and danger to encounters, keeping players on their toes and making them think twice before underestimating the legendary creature's potential. Players will need to adapt their tactics and strategies when facing a creature that becomes more dangerous and unpredictable as its life force wanes.

The legendary creature possesses a rare and formidable power called "Perfect Mimicry." Once per long rest, as an action, the creature selects a creature it can see within 60 feet of itself. The legendary creature magically transforms into an exact physical and mental replica of the chosen creature, retaining all its abilities, hit points, spell slots, and even legendary resistances and actions, if applicable.

While transformed, the legendary creature gains access to all the abilities and features of the copied creature, using its own statistics for saving throws and attacks. It can also speak, understand, and replicate the copied creature's mannerisms perfectly. The transformation lasts for up to 1 hour, and the legendary creature can choose to end it early by using an action.

The legendary creature can use any of the copied creature's abilities, spells, and attacks, provided that it meets the necessary requirements (e.g., having the required spell slots or meeting prerequisites). The Perfect Mimicry ability grants the legendary creature unparalleled versatility in battle, allowing it to adapt its tactics to counter the party's strengths and exploit their weaknesses.

Adventurers facing a legendary creature with Perfect Mimicry must be constantly on guard, as it can switch between forms and abilities to confuse and deceive its opponents. The challenge lies in determining which version of the creature is the real one and finding ways to outsmart its duplicity. Players will need to use their wits and resourcefulness to prevail against this cunning and elusive foe.

The legendary creature possesses a malevolent ability known as "Soul Draining Grasp." As an action, the creature makes a melee spell attack against a target it can reach. On a successful hit, the target must make a DC 25 Constitution saving throw. On a failed save, the legendary creature drains the life essence of the target, reducing their maximum hit points by an amount equal to the damage dealt by the attack.

The creature regains hit points equal to the amount of maximum hit points reduced from the target. The maximum hit points reduction lasts until the target finishes a long rest, during which time it cannot regain the lost hit points even from magical healing.

Using Soul Draining Grasp requires concentration, and if the legendary creature takes damage while concentrating on the effect, it must make a DC 20 Constitution saving throw to maintain concentration. If the legendary creature succeeds, it can continue applying the maximum hit points reduction for the remaining duration; otherwise, the effect ends.

This fearsome ability allows the legendary creature to weaken and sap the life force of its adversaries, making them more vulnerable and easier to defeat. It can turn a once-formidable opponent into a shadow of their former self, heightening the sense of danger and urgency in combat encounters. Players will need to be extra cautious when facing creatures with Soul Draining Grasp and must come up with creative tactics to counteract this harrowing ability.

The legendary creature possesses an ability called "Enfeebling Touch," which allows it to reduce a target's ability score temporarily. As an action, the legendary creature must make a melee spell attack against a creature it can reach. On a successful hit, the target must make a DC 25 Constitution saving throw. On a failed save, the target's chosen ability score is reduced by 4 for 1 minute.

The legendary creature can choose one of the following ability scores to target with the Enfeebling Touch: Strength, Dexterity, Constitution, Intelligence, Wisdom, or Charisma. The targeted creature's affected ability score is reduced by 4, potentially lowering its modifiers and related skills and saving throws.

The target can repeat the saving throw at the end of each of its turns, ending the effect on a successful save. If the target fails three saving throws in a row, the ability score reduction becomes permanent, and the target cannot benefit from Enfeebling Touch again.

Using the Enfeebling Touch ability requires concentration, and if the legendary creature takes damage while concentrating on the effect, it must make a DC 20 Constitution saving throw to maintain concentration. If the legendary creature succeeds, it can continue applying the ability score reduction for the remaining duration; otherwise, the effect ends.

This powerful ability allows the legendary creature to cripple its opponents by weakening their physical or mental prowess. It adds an additional layer of danger to encounters, as characters may find their abilities hampered by the legendary creature's touch. Players must be cautious when facing creatures with Enfeebling Touch and may need to plan their strategies accordingly to counter this debilitating effect.

The legendary creature possesses an ability called "Soul Siphon," which allows it to steal an ability or spell slot from a target creature. As an action, the legendary creature chooses a creature within 60 feet that it can see. The target must make a DC 25 Charisma saving throw. On a failed save, the legendary creature gains one of the following benefits, chosen by the target:

As a legendary action, the creature targets one creature it can see within 60 feet and unleashes a malevolent force that disrupts the target's ability to heal. The target must make a DC 20 Constitution saving throw. On a failed save, any magical healing or hit points restoration the target receives is negated until the end of its next turn.

Additionally, any healing spells or effects cast by the target on itself or others are also nullified until the end of its next turn. Potions or abilities that would restore hit points to the target during this time have no effect.

The target becomes aware of the malevolent force acting upon it, and this realization can be a source of fear and desperation as it struggles to find ways to overcome the curse.
