Re: I need Tips to defeat a gnome boss
i assume you mean the Trial Guardian from the Trials of Gnomus.
My suggestions would be to, firstly, use a character variant which you feel that you are good with; if that variant happens to have fire, toxic, or ice effects all the better.
Your next tactic should be to make use of the Bot/Pot spawning sites before opening the Portal; planting spawnables which have freezing or stunning attacks can help you with the standard Gnome troops.
Your third tactic needs to be to stay mobile; getting cornered or surrounded is bad news. Use the columns in the room to block fire from the Guardian and try to keep him a good distance away while you clear out Gnomes from behind you and don't be afraid to simply run and dodge your way across the map so that the Gnomes are grouped mainly on one side.
Don't try to fight at close range, and don't rely too much on Zoomed weapons since you move slower while aiming and that makes it easy for you to get surrounded.
Preferably fight the Guardian from as far away as you can manage and if there are a lot of Gnomes in the room focus on them over the Guardian and use mobility and the columns to block any incoming fire.
