I'm looking for a script that allows to make the following skills:
1. DoT (damage over time): the basic "poison" effect of RPG Maker XP s*ks. With damage over time spells u can set the amount of damage u want deal during X turns.
Example: 300 damage/10 turns, that means, that after each turn, the afflicted character suffers 30 damage.
Why is it better than the normal poison effect? Because u can apply DoTs on bosses as well since they dont deal damage based on their maximum health %.
2. HoT (healing over time): is works the same way as DoTs, but they heal HP instead.
HoTs and DoTs are well-known because of World of Warcraft, still I didnt found any script with this function.

(RPG Maker 2003 had this function, but unfortunately it has been removed in XP.)
I dont know how hard it is to create, but it would a really useful thing.
The following functions would be nice:
1. Allow to have more DoT and HoT effect on a character.
2. Allow to have HoT and DoT at the same time.
3. Show each DoT's damage, each HoT's healing effect.
Thank you for your help guys!
