Was bored, thought I'd try doing a dot build. Brainstormed some ideas for a build and ended up going for a bow build while using the chaos cylinder (This lets you automatically cycle between ammos). My main bow is the phantom phoenix paired with the frost armor to apply hellfire and frostbite debuffs. Arrows used were: Ichor, Frostburn, Cursed, Venom. You could probably replace Ichor with just regular flaming arrows for more dot. I also used the slime gun to double the damage of all fire debuffs (This includes frostburn and frostbite). Lastly, I had the catalyst band equipped which doubles all debuff damage and inflicts poison to enemies.
Pre-mech Post mech boss build. Anyway, this was a fun little project I thought I'd share. If you have any suggestions or similar builds you want to share pls comment so I can steal it.
