Mods/The Aether/Sentry

Sentry is a mob inside a Bronze Dungeon, which will spawn when you step on a trap. (Traps look exactly the same as the other blocks.) Upon spawning it will follow the player and explode. When exploding the player gets some damage and is launched pretty far. It should be noted that a sentry hops in the same manner as swets and slimes, though in appearance it closer resembles the lightstones of bronze dungeons.
