This is my bucky build. I'm aiming to maximize damage output, while staying alive in cosmic content. 

Nothing is set in stone and always a WIP.

Opening Rotation:

 Hold down left click 

 To apply Vulnerability   

 Drain all charges!
Sig to grab them all 
 While boosted. This is reset after using the mag disc mine!
 While everything is grouped (cleave execute!!!!)
 then  while buffed. 

Use  As a filler while mobs are grouped

Try to not delay or  as these hit like a truck. Pick one or the other to use for your Brutal Assassin (5th row trait) proc. They do similar damage, but if you have a good tight cluster of mobs,  will hit them all!

Thanks for reading and enjoy Tahiti!
