I'm contemplating tier2ing my Fire Thunderforged handwraps for better DPS (tier 1 is simply Touch of Flames for max damage). I don't want to use any shadow scales (saving up for armor), which rather drastically limits choices.

The slow looks OK, but I'm expecting my shadow wraps to eventually end up upgraded to a more "anti-trash" pair, and was hoping for my fire ones to be best for boss DPS (assuming no fire immunity anyway).

Is Wrath of flames any good? On the surface, it looks solid. 5% chance of a ~300 explosion adds 15 damage per hit, even against a single target. But... that 50 Reflex saves is a pretty huge caveat. If all EE bosses save every time, I'm looking at only 7.5 damage per hit. If they have evasion, zero.

Do I bother with spending the fire scales for it, or am I better off just adding an extra slot and sticking in a Sov Ruby or something? That woudl be only 5.5 damage per hit, but a reliable 5.5.
