Trivia

Unlike most standard Abyssal enemies, the PT Imp Group is relatively small and fast. Attacking them with large-caliber guns will not do much damage; smaller guns are recommended to deal normal damage.
On 11/20/2015, a tweet revealed a bug that prevented destroyers from being able to hit the PT Imp Groups. As a result the devs readjusted the damage calculations in a live patch update on the same day.

PT Imps were introduced during the Summer 2017 Event. They have a very high evasion rate and are next to impossible to hit with normal shelling and torpedo attacks. This even includes special attacks. In order to sink them, your ships will require specific equipment setups.

Important Notes

Small Caliber Guns + Lookout + Machine Gun is the best anti-imp setup.
It is inadvisable to run anti-imp setups on any ship but destroyers because it compromises their combat effectiveness.
Having a reinforcement expansion is important because it allows the ship to not waste a slot on a machine gun.
The values presented above are theorised to be fixed hit rates.
- This means they are unaffected by any outside factors.
