Can't I whack around with this weapon only? I guess it works fine with other mob too. (Unless it's not that effective)
Ok in this case I'll roll away the INT with a socket.
Eh may I ask, how does increase DMG against elite help while the damage only base on their current health?

U can use it but..there is no synergy with cru..like Fotf or BoP or GF weapons. U get more DPS with you wield those fails as a cru.
The damage by Furnace is % of current health. Hence if monster health is 400M, when the bonus proc, you do 8% x 400M = 32M alone. Here is the kicker..the 32M is white damage , i.e base damage which can never crit. However, bonus to E works on white damage, hence you will want to stack that. Assuming you have a 30% E bonus soj + 20% diamond in weapon = 50% E bonus. You net damage will be 32M + 16M =48M lo
Now lets assume its T6 RG ..Ghom, who has 4B life. Your first hit on Ghom will hit him for 480M lo...power or not?
