That Unsheathe effect on Dragon Tooth?

I just tried..TopHat(Bapho) n Full Beard(Bapho) Using DT..TopHat better then..soo that unsheathe effect on it?

 

It could easily be proration or stability. Halberds naturally have low stability so it is possible that you ran into a low roll vs. a high roll.
Based on code datamine, there is no known unsheathe effect on DT.

 

either prorate and stability, and u can reach high dmg with full beard

 

Maybe you casted it from 8m or further away?

But yeah the damage can vary greatly, I've experienced cases where one hit did almost 3 times the other hit.

 

You have to consider 3 things when using dragon tooth
1.Stability , mostly because of the low roll and high rolls Halberds tends to have.
2.Proration , who knows , for example maybe you used Dragon Tooth during the enemy has +5 prorate when equipping Tophat and +0 Prorate when equipping Full Beard.
3.Whack Passive , Well Whack has a small chance to increase some daamge right? Might have happened to you during those occasions
