Kaisyl_Vampirism

/*:
* @author Kaisyl/Synrec
* @plugindesc (v2) A plugin which adds vampire effect to a designated state.
* @help You must have the attack type set to HP/MP drain for this to work.
* Plugin Changes:
* v2: Fixed some syntax errors and bugs.
*
* You will not drain more HP/MP than the target's current HP/MP.
*
* Only one state (chosen in the plugin editor) is allowed
* to be the vampire state.
*
* To edit the drain text, please do so from your database.
* If necessary, I will implement it here.
*
* @param Global Vampirism
* @type number
* @decimals 2
* @default 0.00
* @desc Control default drain multiplier.
*
* @param Minimal Vampirism
* @type number
* @default 1
* @desc Flat minimal value of drain effect.
*
* @param Vampire State
* @type number
* @default 11
* @desc The state ID which gives vampire ability.
*
* @param Vampirism Value
* @type number
* @default 1.00
* @decimals 2
* @default 1.00
* @desc Control the state drain multiplier.
*
* @param Remove 0s Popup?
* @type boolean
* @default true
* @desc Remove 0 damage and 0 absorbtion from battle.
