Is Firework Technician Worth It?
Temporary full-detection buff at wave start can save you from placing extra dedicated detector towers
Firework procs add splash damage and Burn on top of your existing towers' attacks for free
At max level, the proc chance cap reaches 100%, making its buff very consistent
Limited to 1 placement per player and has no firerate of its own, so its value depends entirely on the towers placed within its range
Firework Technician Tier Rating by Mode
Best Loadouts With Firework Technician
Best placed near your main DPS cluster so its firework procs and detection buff apply to as many towers as possible
Pairs well with towers that lack Hidden or Flying detection, covering their gaps at the start of each wave
