##### Optional Rule: Intelligence-based Warlock
The Architect is a patron that is well suited to a more intellectual than charismatic warlock. Here are are a set of optional rules to play a warlock whose primary ability score is Intelligence rather than Charisma.
Saving Throws. Your saving throw proficiencies become Intelligence and Wisdom instead of Charisma and Wisdom.
Spellcasting Ability. Intelligence is your spellcasting ability for your warlock spells, so you use your Intelligence whenever a spell refers to your spellcasting ability. In addition, you use your Intelligence modifier when setting the saving throw DC for a warlock spell you cast and when making an attack roll with one.
**Spell Save DC** = 8 + your proficiency bonus +
your Intelligence modifier
**Spell attack modifier** = your proficiency bonus +
your Intelligence modifier
Class Features and Invocations. Whenever a warlock class feature or an Eldritch Invocation refers to your Charisma modifier, refer to your Intelligence modifier instead.
Multiclassing. The Ability Score Minimum of your Multiclassing Prerequisite is Intelligence 13 instead of Charisma 13.

### Extraction Scout
The first extraction scout was created by the Architect as a means of traversing the world beyond and retrieving the various materials they needed for their craft. Soon, more came after the first proved its usefulness. They form the foundation of the Architect's hierarchy of creations. They are single-minded and thoroughly obedient. An extraction scout can be found anywhere there is ore, harvesting and collecting as much as it can to bring back to its creator. Its defensive measures are limited, but it is capable of engaging with enemies it comes across by utilizing its spike-like appendages. These spheres of metal can be bound to another master, though it always comes at the permission of the Architect. When its servitude shifts, an extraction scout regards its new master with reverence and stalwart protectiveness.
In addition to charcoal, incense, and herbs, summoning an extraction scout requires the placement of four gems of any value along the edge of the brazier. The summoner beseeches the Architect for the employ of one of their creations as they speak the incantation over the flame. Gifts of crafted make, particularly those handmade by the summoner, aid in the request. Once the Architect hears the summoner's plea, they consult their Grand Design. If the scout's permittance doesn't uphold the design, the flame is instantly snuffed out. If everything is in accord, the flame coalesces into a ball and a gold, plated sphere forms in its center. The plates unfurl into four forelegs that reach out and pluck the gems from the brazier's edge, returning them to the summoner as they exit the basin. With the first task dedicated to its new master complete, the extraction scout's service begins.
