Condenses the caster's magical energy into the form of a violently crackling blade. Each time the caster successfully hits with a melee attack while the spell is active, this blade will rend a path back and forth through nearby foes, dealing irresistible damage.

Casting this spell temporarily drains *all* of the caster's remaining magical power to constitute the blade, but this energy will be returned to them as soon as the blade ceases to exist. Each point of magical power sequestered this way slightly increases the damage the blade inflicts.

Rending Blade is a level 4 Forgecraft/Conjurations spell that temporarily uses all of your remaining MP to create a magical blade that attacks when you hit with a melee attack.

Reavers start with this spell in their library.

Useful Info

Summons a rending blade, which is initially leashed to the caster. Whenever you hit with a melee attack, the blade attempts to dash through enemies using Rending Slash, dealing irresistible damage to all of them. Hitting multiple enemies in a single attack, such as with an axe, can trigger the blade multiple times at once (max. 3 times per swing[1]).

The blade can dash through up to 4 tiles. It will prioritize the most HD of enemies in can hit in one dash without leaving your line of sight, iterating all possible paths from its current position and all adjacent positions if necessary.

Casting this spell costs a minimum of 4 MP. Any MP beyond the minimum is temporarily lost, although any extra MP increases the effective spellpower of Rending Slash: the bonus is equal to 50 * log2(1 + extra_MP/10)%.[2] When the blade dies or expires, the extra MP used to form it is returned to you. For a Djinni, casting the spell instead costs only 4 HP.

The damage of the blade's Rending Slashes equals 2d(6 + power/12).[3]

Strategy

A spell primarily for hybrids.

Remember that MP is required for certain divine abilities, so watch out when using this spell.

This spell has great synergy with Axes and Wu Jian (whose abilities don't use MP), as they can trigger multiple slashes per action. In addition, because it is a source of flat damage, fast attacking weapons like quick blades receive a greater benefit.
