Can someone give a code for this spell

I want a spell that targets a unit with mana points.The targeted unit loses its mana over time but gains great hit points regeneration
-lvl1 loses 3 mp per sec increses hp regen by 3 per sec
-lvl2 loses 5 mp per sec increses hp regen by 5 per sec
-lvl3 loses 8 mp per sec increses hp regen by 8 per sec

plzzz i need some help here

Just use negative values on regeneration for the losing mana part.

Very simple. No triggers needed. Use rejuvenation for base. Change the mana bonus per second to minus value and change the life bonus per second to positive value. That is all.
