Fireworks

Complete all areas with a Tinkerer cat to unlock Fireworks, a trinket item. This achievement requires clearing every area in the game using the Tinkerer class. The Tinkerer's turret-based strategy rewards patient setup play and scales well in longer fights. Deploy turrets in defensible positions early, and let automated damage carry you through each encounter. Build Nuke provides burst for priority targets, while Mech Suit offers a temporary power boost for tough fights. Repair keeps your turret network functional. The +4 INT bonus makes gadget damage scale exceptionally well into later areas. The Tinkerer's -1 Luck penalty reduces crit chance, so build around consistent turret output rather than hoping for lucky hits.
