Based on the Sonreir fit here: https://abyss.eve-nt.uk/fit/3044

Abyssal Battery is 2000+ PG and 33% Cap Warfare Resistance.

Less DPS but more application. Clears sites slightly faster in general but the extra DPS of Sonreir's fit is very helpful in the BS rooms.

Target priority for most rooms: Neuts>>Webs/Damping>>EWar>>DPS

Use 2 x Geckos, 2 x Valkyries, and 1 x Warrior in most rooms and fly the Ishtar to reduce DPS i.e:

• maximise transversal in BS rooms (Karen, Overmind, Marshall, Leshak) while staying out of blue clouds. The Karen wrecking shot will put you in armour. Two wrecking shots makes the room spicy!
• fly away from multiple Starving Vedmak waves to give you time to kill them before they kill your cap (use speed clouds if you can),
• Kite Kikimoras (kill tangling and Ghosting first after any neuts)
• Devoted waves - Kill Smiths then Knights while kiting the wave and spiral into the gate.
• Drone frigates - I use Berserkers and split the DPS 1 for 1. It is a bit of a click-fest but clears the room quickly.

Most dangerous rooms are:

• 4+ Starving Vedmaks with Tangling Damaviks - hope for a speed cloud! Fly directly away and concentrate on killing as many neuts as quickly as possible. I normally kill the supporting Starving Damaviks first (splitting DPS), and then the Webs. Manage your shield booster manually to preserve cap.
• Blastlance Drone Battlecruisers - keep away and don't underestimate their DPS. If they get close they will wreck you!
• Blastlance Frigates - a large wave of just Blastlance frigates will eat through the tank. Use the Berserkers 1 on 1 while flying away. Kill webs to maintain speed.
• Multiple Ephialtis and BS rooms - If you do not maximise the efficiency of your DPS you will come up against time. I lost one of these to time with a Full Ephialtis room, followed by and Angel room that wouldn't leave my drones alone, and then a Karen room with a huge number of Ephialtis in support.
