Prerequisites: Caster Level 31, Multitarget (Feat), Improved Multitarget (Feat), Greater Multitarget (Feat)
Related: Perfect Multitarget
Benefit: You can alter spells that affect one target or more (including rays) to affect up to four more such creatures. This may be used on attack spells, buffs, or heals, so long as all targets are within range of the spell when cast. This feat has no effect on Area of Effect Spells, which have an unlimited number of targets already. Touch spells (such as Perfect Multitarget Cure Critical Wounds) might require all affected creatures to be adjacent to the caster's space. (Note that Reach Spell is a powerful companion for this feat.)
Special: This metamagic feat raises the spell slot required by six, and adds four additional targets, rays, or effects to the spell's casting each time it is applied. In addition, if the spell's effect (such as a Ray, or a melee touch attack) requires a to-hit roll, this feat adds a +4 circumstance bonus to those to-hit rolls, which stacks with all similar bonuses such as from Weapon Focus and similar feats, implement bonuses, etc.
Special: If, at the time of casting, this feat (combined with any other target-adding effects) causes the spell to have more creatures-worth of damaging effects than there are enemies in the current combat, then the caster may, if they wish, choose enemy creatures in the current combat and attack one or more of them twice with a single casting of the spell, until they run out of effect. No creature may be targeted more than twice with a single casting. Resolve each of these attacks or effects separately. The GM adjudicates any unusual circumstances.
Example: A Cleric casts Perfect Multitarget Energy Drain, and generates 5 Ray attacks with this casting. In the first round, there are six enemies, and the Cleric may attack five of them with one ray each. In the second round of that same combat, the same spell is cast with 5 more rays, but this time, there are only three enemies alive. The Cleric may attack all three of them once, and then may choose two of them to attack with a second ray each. In the third round, the cleric casts the same Perfect Multitarget Energy Drain again,(why change what's working), but there are only two enemies left alive. They may attack both enemies with two rays each, but the last ray is lost to no effect, since you cannot target a single enemy more than twice. Alas.
Level Increase: +6 (A Perfect Multitarget spell uses up a spell slot six levels higher than the spell's actual level.)
