Power Word Bleed (5e Spell)
From D&D Wiki
|Casting time:||1 action|
You speak a word of power that causes the blood of one creature you can see within range to burst forth. If the target has 100 hit points or fewer, it is subject to massive bleeding, taking half its current hit points in damage up to a maximum of 50. Otherwise, the spell has no effect on it. A target is also unaffected if it is immune to being charmed, is undead or a construct, or has no substance in its body that is the equivalent of “blood” (for instance the Warforged ‘blood-like’ fluid).
While the target is affected by bleeding, any terrain around it in a radius of 5 feet becomes difficult terrain at the end of the target's turn due to the growing pool of blood. The target also has disadvantage on attack rolls and ability checks, and saves. Finally, if the target tries to cast a spell, it must first succeed on a Constitution saving throw, or the casting fails and the spell is wasted.
A target suffering from bleeding (or any creature within touch range of the target) can, on its turn, take an action to stanch the bleeding wound by succeeding on a Wisdom (Medicine) check against your spell save DC. The wound also closes if the target receives magical healing of 6th level or higher.
