Spells: Damage applied over multiple rounds?

I don't think it is possible. However, it would be conceivable to do an effect that deals damage starting high and ending low, by using multiple gamemodifiers.

What are you calculating? 

EDIT: You can use calculate to derive the value, and use <Duration>, but I don't think it calculates each turn.

Thanks guys.

For example, a spell that deals 2*N damage per round where N is the number of rounds it has been applied. Duration Int/5 (or something similar).

I'll take a look at multiple round effects and play around a bit. 

Well, I know that you can't calculate to Duration. You can only use calculate to derive Value, MinValue, and MaxValue. I've been trying to think of a way to make the first part work, but without having a variable for the round (or not knowing what it is), I'm not sure you can do it.

what about the poisonshot ability of the blackwidow spiders for ideas?

Thanks for the help guys. I'll give the poisonshot ability a look today. If I can get it to work, I'll post the xml as a reference for others.

There has to be a duration mechanic in there. Haste, slow, dominate, etc all have a duration on the tactical map as does the new flame spell that burns in a square for a nnumber of turns.

The question is if he can do a spell that does different things in each subsequent round. You guys are confusing the issue.
