How do I create EXACT Damage over time spells?

[Narzerus]

I was wondering, how can I create Damage over time effects.
I wish to add them to monsters, for example

A monster that leaves a FireCondition that deals 300 dmg, every 5 secs,for 20 secs.

If you set this on a monster
Attack=Firecondition(or any other condition), min"-300" max="-300" the following happens: the server "divides the -300 dmg in pieces", and instead of hitting 300, it hits like this = -50,-49,-48,-47,-46 and so on

look at the old exevo mas pox script, its all in there. or just any damage condition that reduces.
