Hazard goggles (Brewer starting item) or magic reflection (Wizard starts with an amulet) can help you survive a potion. Other than that, you'll have to get better at luring and killing enemies around corners without them attacking you. Firestorm gnomes just put your skills to the test because it's basically a one shot kill + even if they miss, they will destroy walls and create a line of sight.
And how to counter it without being a brewer or somehow getting a magic reflection? Trying to dodge it like any normal ranged enemies is nearly impossible because of potion's protectile speed. Does it has limited number of these potions? Or any other tips?
@@wojtek6469 They only have 5 potions and if you have space (so only possible in the spawn room) you can strafe from side to side to avoid. In any other case, it's not about dodging the potions, you need to kill the gnomes before they get a chance to throw. I recommend checking out my kiting guide for some tips on how to deal with Barony monsters safely.
