Adding bonus damage is another multiplier. It’s earlier in the formula, but FL4K get’s a sizable amount from the Master tree alone, about 80%-100% in a normal master spec.

Also, while I understand we’re talking within the context of Fade Away where you hit guaranteed crits, increasing any other type of damage (gun, bonus, splash) increases crit damage by the same amount.

@OP A typical Hunter-Stalker spec has Galactic Shadow for 15%, Big Game/MDG for and 13%, and a few points in Hunter’s Eye to round out the tree for 9% crit for around 40% crit. Master builds would have 40% bonus damage from Frenzy, 15% from skag+Barbaric Yawp, and 14% from pack tactics. for a total of about 80% bonus damage.

Assuming the Stalker tree is specced down to the Power Inside (which provides 50% bonus damage and 5% crit if you take Gunslinger Jabber) you have:

Hunter/Stalker- 50% +Interplanetary Stalker bonus damage, 45% crit

Master/Stalker- 130% bonus damage, 5%crit

You can shoot for the best of both worlds and go for this

You get the most powerful pet bonuses and a large amount of bonus damage. You don’t get much crit, but if you want your pet to be a damage dealer, this build with the Deadeye is the closest I’ve gotten so far.
