Wake of Fire can apply damage every 5 frames (5 times per second) due to its 4 frame Next Delay. Vast majority apply Fire Damage, although Arctic Blast applies Cold Damage, Diablo firestorm applies fire and physical damage and Diablo lightning applies Lightning Damage and physical damage. Intent is to prevent integer damage reduction from being too powerful a counter when small amounts of damage are applied by multiple missile collisions. In Hell Diablo lightning only applies maximum 26.25 base physical and 52.5 lightning damage per collision, which would otherwise be easily negated by DR 40 and Lightning Resist 75% (base physical damage would be negated and excess DR would then negate base lightning damage after resistance applied); but due to this modification, DR 492 (an impossible amount in an unmodified game) is actually required to achieve this (DR 40 and LR 75% only reduce maximum base damage by ~46%). However, since damage is typically smaller the more missile collisions are used to apply it, this modification is normally less effective as the number of missile collisions involved increases. In Hell Diablo firestorm only applies maximum base 2 48/256 fire and 240/256 physical damage per collision, although up to 30 missiles can collide with a player with each cast and each missile can apply damage up to 35 times, resulting in up to 1,050 collisions (compared to just 17 collisions for each lightning cast at a single stationary target); thus despite the modification, DR 37 and Fire Resist 75% would still negate base physical damage and excess DR would then negate base fire damage after resistance applied.
