Stormcloud Halls

Stage 13 of 18, in Stormcloud Depths.

Enemies in the campaign

9 kinds of enemy come down the paths here, and 7 of the 15 waves bring flying enemies. Counts are for the whole campaign run.

Sunray Tower. A tall tower that harnesses solar energy.
Sunray Obelisk. Smaller structures for redirecting sunlight. Its Build Obelisk action constructs one such obelisk for 150 gold, with 2 of them on the map.
Charging the Sunray Tower. Stormcloud Sorcerers approach the Sunray Tower to charge it: full charge requires 28 points, and it accumulates 0.61 points per second when 1 sorcerer is present, 0.74 when 2 are, 0.87 when 3 are, and 1 when 4 are. Every sorcerer has 120 health, no armor, and deals 4-6 physical damage per second.
Sunray. Once fully charged, a tap fires a ray lasting 2 seconds that hits ground enemies within a 50 radius for 75 true damage every 0.1 seconds. If Moglok-Hai is standing on the ground, the ray targets him instead, dealing 40-50 true damage every 0.25 seconds over 1.9 seconds.
Obelisk rays. Whenever the Sunray Tower reaches full charge, every rebuilt obelisk charges alongside it; a tap then unleashes 10 rays spaced 0.27 seconds apart, each hitting whichever enemy within 200 has advanced furthest along the path for 48-72 true damage.
