By RAW, does this work:
Take one part Monk 2 and one part Psychic Warrior 18.
Add Tashalatora, which makes this characters base unarmed damage like a lvl 20 monk.
Add 4 Ectoplasmic Fists, (ECS 264), this will add 4 size increases to the damage, 12d8
Pour some of the monks rule that her unarmed strikes counts as weapons so they can be enchanted by magic and effects.
Mix with the Psychic Warriors' power Vampiric Blade.
Shake, stir, serve.
Does this character, with these things active and available, deal 12d8 damage and heals half of that damage for each attack that hits?
Problems I see:
1. Ectoplasmic Fist seems to add one size to each limb.Which by RAI, if you think about it, should mean that only that limb is increased. As such, 4 of them would end up with each limb counting as one size larger, not all of them four sizes.
But by RAW this is fuzzy.
