Guard mode
Section titled “Guard mode”After start, the radius grows from 0 to about 50 tiles.
- Enemies in range get Electrified for about 0.5 s
- About every 0.67 s: the nearest player within about 50 tiles holding a chargeable item that is not full gets an arc. A hit adds +0.1 charge
- Costs about 30 UE/s while UE > 2
Attack mode
Section titled “Attack mode”About every 1 s, it picks the nearest enemy:
- Search radius about 44 tiles
- 60 UE per shot
- Arc: 32 damage, knockback 2, pierce 3, about 0.5 s local invulnerability
Damage is low. It can keep hitting a line of small enemies.
Switch and idle
Section titled “Switch and idle”- Bench 1:1 recipe swap
- Right-click the placed tower
- Wire signal on the tile
No UE cost. Stored UE stays. The tower pauses if the player is beyond about 250 tiles, and resumes on return.
Chargeable targets include the Laser Pistol and the Electric Mini Rocket. Attack mode spends a lot. A Thermal Battery next to it helps.
