'''Rending Blade''' is a level 4 [[Forgecraft]]/[[Conjurations]] spell that temporarily uses '''all''' of your remaining MP to create a [[rending blade (monster)|magical blade]] that attacks when you hit with a melee attack.

[[Reaver]]s start with this spell in their library.

==Useful Info==
Summons a [[rending blade (monster)|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 undodgeable 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 player action<ref>{{source ref|0.33.1|spl-summoning.cc|4782}}</ref>).

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 <code>50 * log2(1 + extra_MP/10)</code>%.<ref>{{source ref|0.33.1|spl-summoning.cc|4740}}</ref> 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 <code>2d(6 + power/12)</code>.<ref>{{source ref|0.33.1|zap-data.h|2661}}</ref>

==Strategy==
A spell primarily for melee-focused hybrids. It is less effective in corridors due to it being unable to attack from behind the player, but does not require much space: a corridor intersection is sufficient to let the Rending Blade reposition and then attack.

Losing access to all your MP is a major downside: even if your character relies entirely on melee, many divine abilities require MP, so watch out before using this spell. It is poorly suited for blaster casters, but [[Forgecraft]] users are less hindered as they can summon constructs before casting this spell. Buff up, summon allies, and ''then'' cast Rending Blade. You don't actually ''lose'' your MP: the blade merely borrows it, and if for any reason the Rending Blade disappears (times out, takes too much damage) then the MP, minus the four MP actually used to cast it, is refunded back to you.

The rending blade attacks once for every monster hit. It has great synergy with [[Axes]] and [[Wu Jian]], which allow hitting multiple enemies at once (as a bonus, none of Wu Jian's abilities cost MP). [[Coglin]]s and [[Okawaru]] worshippers under Finesse can attack quickly, and fast weapons like [[quick blade]]s naturally benefit. Alternatively, [[Polearms]] make this spell easier/more flexible to use, as the reaching provides space for the Rending Blade to function.

[[Coglin]]'s <code>SpellMotor</code> gizmos particularly synergize with the Rending Blade: <code>SpellMotor</code> will make your Coglin attack in melee when casting spells, so if a monster is in melee range when you cast Rending Blade, you: (1) summon the rending blade, (2) attack in melee, possibly hitting up to two times, and (3) thereby trigger the rending blade into actually slashing. Note that reaching weapons will also get triggered by <code>SpellMotor</code> against monsters two tiles away. Increasing your <code>Rev</code> with the <code>SpellMotor</code> will also lower the cost of spells, so natural MP regeneration even while the Rending Blade is out will let you cast up to level 4 spells occasionally, with excellent turn efficiency if any monster is within your melee range: (1) cast any spell, (2) attack in melee, possibly hitting up to two times, and (3) thereby trigger the rending blade.
