Life Essence Harvest

Life Essence Harvest is a passive feature that causes creatures killed by spells to give the wielder Spell Slots. They can only be used for Necromancy Spells.

Description

When the wielder kills a hostile creature with a spell, they greedily absorb its energy and gain  Life Essence until their next Long Rest.

Condition: Life Essence

 Life Essence

Duration: Until Long rest

• Affected entity has absorbed a creature's essence. It can use that essence to cast any Necromancy spell without consuming a spell slot.

How to learn

Granted by the weapons:

• Staff of Cherished Necromancy

Used by creatures:

• Mystic Carrion

Notes

• Life Essence Harvest has no cooldown and can be triggered without limit.
• Killing a creature with a spell granted from  Life Essence does not provide a new charge of  Life Essence.
• Indirect spell damage from sources like  Spirit Guardians does not provide a charge of  Life Essence when killing a hostile creature.
• Per the GreaterNecromancySpellFilter() .khn script, this effect is intended to allow the casting of an extra Necromancy spell only if the spell level is equal to or lower than the number of Life Essence turns the wielder has. However, this restriction is currently non-functional, and any level of Necromancy spell can be cast using the effect. Though none of the tooltips explicitly mention this functionality, Life Essence displays the number of turns the wielder has on its tooltip.

Bugs

• The effect of this passive is consumed if active when the character casts a cantrip from the Necromancy school, despite the cantrip not being highlighted in the character's cast bar.
