They are midnight blue with an orange shell covered in pale green spikes.
- Protoform Abilities - Can roll into a heavy spiky ball for bashing.
- Cannonshot - Arms tuck in to form a large spiky cannonball.
- Blambarrage - Barrage of spikes fire from the shell.
- Firekraken - Grabs opponents and carries them off, bashing them through walls and objects.
it can probably beat an hoprock by slamming at it right as an armashelt
harmashelts are ghouls suited for raw offense, as they have a limited moveset wich only involves offensive attacks: cannonshot can be used to destroy walls, obstacles and of course to attack enemies. blamabarrage is a ranged attack, that allows the harmahelt to strike while not making contanct with its target: this move is useful to slugs that can only do significant damage when they're close to their targets, like rammstones, hexlets, enigmos and flatulorhinkuses. firekraken is a tricky move to land, but the reward for the former landing is incredible: the target gets seriously damaged, and considering how rough and violent the attack is, the enemy slinger will probably lose its blasters and slug canisters. this slug has a great matchup against hoprocks and grenuke slugs, and has a horrible matchup against healer slugs
