And yes that is prolly greater than BM fang. off the top of my head its 4.2 speed when used in one hand. It also has stats that kill the BM fang. and at lvl 10 it summons javelins in your inventory that are insta ground target DoT's.
The golden spear is gonna be the replacement for BM fang. Thing is every moron under the sun will have one. take about 30 mins to get with a decent full group.
your alternatives to that really are Sun weapons, legendary blades, or theres a few other decent artifacts. (traitors, croc etc)
BM fang will be a reasonble weapon to use but it wont really be the best.
