I like how sapper is getting some attention but it’s missing key attributes to make it more reliable. Here are some suggested attributes.
Detonate: A on and off toggle so you can only detonate enemy traps and increase the maximum amount of detonations by 2.
Claymore: a on and off toggle for instant detonate or remote detonate. Instant detonate does surrounding area hit.
Broom trap: attribute to double the speed of broomtrap in exchange for more so consumption
Collarbomb: overheat x2-x3
Stockades: bleed attribute
Spike shooter: cool down decrease and actual piercing that go through all enemies at a given range.

can’t kill a sole mob (especially bosses that don’t summon traps) with it.
