@plugindesc v1.0.1 - Customize the drain amount
@author TheoAllen

@help
♦ About:
You deal 100 damage, but you don't want to drain 100 HP.
Maybe you only want it only drains 25, or maybe twice of it.

♦ How to use:
Put tag <drain rate: n>
Replace n with numbers in percentage.

Putting <drain rate: 50> will drain the HP/MP based on the 50%
of the damage dealt.

♦ Thing to note:
The battle message log does not reflect this change. I don't
want to deal with it. Please, change the drain message into
something that makes sense such as 

"%1 took %3 damage!"

Or seek for a plugin that disables it all together.
