Evaluating a secret unit comes down to cost efficiency per upgrade tier. Dropping Demon King onto the field requires an initial placement cost of $1,850. That entry fee offers moderate base damage, but the tower functions purely as a liability until you push past upgrade Tier 4, where its attack pattern transforms from a targeted circle into a sweeping 180-degree cleave.
Reaching Tier 8 unlocks maximum output for a combined expenditure of $84,600 in deploy cash. At this cap, the attack cycle settles at a fast 4.2-second attack speed (SPA) with an expansive 48-stud range. Delivering 396,000 damage per strike at max level yields an exact unbuffed output of 94,285 raw DPS.
When you account for standard support rotations, such as maximum damage amplification from buffer units and relic banners, the sustained burst climbs well past 285,000 DPS per tower. Because the placement cap allows two copies, an optimized choke point outputs over half a million damage every four seconds.
