Haemorrhage

Normally, bleed effects do not stack, i.e., if a being is afflicted by multiple bleed effects, they will only suffer the damage that is inflicted by the most powerful bleed effect that afflicts them. However, while a being is affected by Haemorrhage, this restriction is removed, i.e. they will suffer the damage that is inflicted by every bleed effect that afflicts them.
Normally, bleed effects do not stack, i.e., if a being is afflicted by multiple bleed effects, they will only suffer the secondary effect that is inflicted by the most powerful bleed effect that afflicts them. However, while a being is affected by Haemorrhage, this restriction is removed, i.e. they will suffer the secondary effect that is inflicted by every bleed effect that afflicts them.
Normally, beings that lack blood (such as constructs) are immune to bleed damage. However, while a being is affected by Haemorrhage, their immunity to bleed damage (if any) is nullified and they are able to take bleed damage as normal; although their bodies still lack blood, the bleed damage that they take is representative of the essence that sustains them being drained away.
Normally, beings that lack blood (such as constructs) are immune to the effects of spells that involve manipulating the blood that is within a being's body (such as the Sanguine Puppet spell). However, while a being is affected by Haemorrhage, they are treated as though they had blood flowing through their body for the purpose of determining whether they can be affected by such spells.
