Guard Mode
Section titled “Guard Mode”Effect radius ramps from 0 to ~50 tiles after the tower starts.
- Continuously applies Electrified for ~0.5 s on enemies in radius
- About every 0.67 s: nearest player within ~50 tiles holding a chargeable item that is not full gets an arc; hit adds +0.1 charge
- Costs ~30 UE/s while UE > 2
Good for bases and AFK spots—harassment plus weapon topping.

- Search radius ~44 tiles

- Arc: 32 damage, knockback 2, pierce 3, ~0.5 s local invulnerability on the target
Low DPS but steady pressure in choke points and event farms.
