i know that missile launcher and fatman do. just found out so does the cryolator. any others?

I think that's it, but the legendary Explosive effect scales with Demolition Expert - so weapons like Spray n' Pray do double damage with four ranks in Demolition Expert, and get more splash damage from the third rank. The telekinesis blast from Lorenzo's Artifact gun scales with it, too, I think.

Non-auto (Rifleman) or Automatic (Commando) weaponry perks stack with sneak attack bonus (Ninja) and with bonus for sneak attack when using a suppressor (Mister Sandman).


At least, I hope I got all the combos right.

gunslinger works with pistol grip mods etc.


Plasma flamer pistol does crazy damage, extended range and disarms.
