Had to comment on this I'm attack build its all random I hit 91 times (attack only) got 380 fangs. One before I attacked 21 times got 100 fangs. Not a single spy used people should quit moaning and enjoy!
I think total damage is used as well as the epic you are running. Therefor, using pot increases fang drops. So light up everyone.
I think its based on bonus from eb completion. gh and big hansels tend to get the biggest bonus which makes sense as to why they get the most fangs
Fang drop most likely depends on stats and plunder. Att builds do get high plunder from att but it falls fast and spy plunder is very low. Hansels get high spy plunder and almoat constant att plunder. So actions the plunder u get and stats r important what i think :/
