Is there any kind of list with the dependence between spells effects and spell power?
For example I have Irina (sanctuary) level 19, with 28 spell power. At this point my tsunami stuns for 1 turn. I remember (long ago) when I first played, I managed to get the tsunami to stun for 4 turns (was pretty OP, but that's beside the point).
So my question is, is there any way to find out when the next spell "level" is achieved? A table or a formula or something?
EDIT:
Seems most people didn't understand what I'm asking so I'll try to rephrase: Is there any way to find out how spells depend on spell power?
Something like: you have 1 spell power lighting bolt does 10 dmg. You have 100 spell power lighting bold does 9999 damage. You have 1 spell power blind duration is 1 turn. You have 100 spell power blind duration is 10 turns.
