Lock and Load: The Reassembled Machinist Guide

Yeah that's how Wildfire works, note that it doesn't include some sources of damage (like turret shots I believe). It just reads how much damage you've done to that target in total during the timeframe, takes one quarter of it and applies it as a single hit at the end of the duration - pretty much just a fancy way to say "25% more damage for 15 seconds".

Gauss Barrel is a persistent buff, once you activate it, it will stay on until you turn it off/change classes, etc. You have to turn it off manually, and it will stay off until you turn it back on manually.

Moving doesn't turn it off, so if you try to fire a weaponskill while running with it on, you won't do anything and you won't fire any autoattacks.
