Overview

- It is highly resistant to mining drills, taking no damage from them. Use this knowledge when designing traps.
- Explosion-based damage, such as from grenades or turrets, deals 50% more damage. Effective in controlled bursts.
- Spike walls are only half as effective due to 50% resistance. Avoid relying solely on them for defense.
