Implacable Crusade

3rd-level necromancy

Casting Time: 1 action

Range: Self

Components: V, S

Duration: 10 minutes

Classes: cleric, paladin

With every enemy life you take, you become increasingly dangerous and difficult to stop. For the duration of the spell, whenever you reduce a significant opponent (a creature no more than 4 HD below your own level) to 0 hit points, you gain a +1 bonus on melee weapon attack rolls, melee weapon damage rolls, and Strength checks for 1 minute and also gain 10 temporary hit points, which last until expended or the spell expires. Your total of temporary hit points cannot exceed your maximum hit points.

If you reduce another significant opponent to 0 hit points while you already have these bonuses, you gain the temporary hit points as noted above and the duration of the bonuses resets to 1 minute from the most recent instance of dropping an opponent to 0 hit points.

If you reduce an opponent whose Hit Dice equal or exceed your own to 0 hit points, or if you drop any opponent to 0 hit points as the result of a critical hit, your bonuses are increased to +2 until the end of your next turn.

If you repeat this feat while this increased bonus is present, you extend the duration of the +2 bonus by 1 round.
