[Resolved] Healing over time Status

I have been looking over the internet for 1 and a half day to find out a status effect that heals over time.
As , Player cast a spell 'Renew' Heals an Ally by an 5% of thier max HP per round, lasts 5 rounds.
I got the script Percentage of Damage but dossent scan status notebox
is there any?
Next is,
I am disappointed about the Poison effect, spils 10% each turn of the targets max HP. thats like 6000 damage for an 60000 HPed Boss o.o
so i was looking for an script/way to base it on attack or Spirit.  for an exemple: Player that has 214 Spirit, Cast an over time damage spell, dealing 214 damage each round.
Or Player that has 76 attack,  Poisons or bleeds an enemy dealing 76 damage every round.
this would be awesome if it is posseble to fix o.o

Try Yanfly's Engine. IIRC, it has functions for that too.
