The Ray of Frost and Disintegrate spells tell you that they cost 20 AP (without runes) to cast but don't tell how much they cost over time. And they say that they do 215/155% of weapon damage but don't say at over what time period it's done.
- How can I get that information?
- What is the time it takes the Disintegrate rune Intensify to reach 202% of weapon damage?
- Does the Ray of Frost rune Cold Blood reduces the cost over time of casting as well?
EDIT: When I say DoT, I mean during the time that the spell is on a monster, and not a DoT affect that stays after the spell was finished casting.
