Spell Balance Suggestions

[Hated]

High scaling based on a stat :check:
Total number of ticks can be reached and unchanged :check:
Full on large aoe that heals you as time passes :check:

It's a good spell imo, dunno if it needs to heal so much while it can do so much more damage.

Just pointing out the facts and don't know how I would say or have an opinion of a change to it.

edit: checked out a gif to see it. doesn't damage, doesn't necessarily change the opponents damage either
