This is one of my fits for Abyss, but should shred Lv3 missions since most of the ships are small anyways. It’s cap stable even for max Alpha, but modify to your skills, and preferences. It’s overtanked, but at first that’s safest, then switch to mag stabs as you gain more experience.
If you don’t have T2 gun skills yet, it may take a couple weeks to get there, but it is very worth it. Train up core fitting and gunnery skills as well. With Null ammo, you can hit out to 22km falloff, and with the MWD, you can close in quick to apply even more damage, or switch to Void to just melt bigger targets. You can also swap out the tracking computer for a web, but you’ll lose some range, and the small ships you should be able to easily hit in Lv3 missions without the web. This is also a pricey build, but you can fit for budget as well.
If you try this out for Abyss, start with Tier 1. This fit will also work in Tier 2 with experience and skills, and without implants and boosters. With experience, skills, implants, and boosters, it may be able to do Tier 3. No dark Abyss with ship.
IMPORTANT: Primary warp disrupting and webbing targets first. Also, fly away when taking too much damage, and pickoff straggling targets on way back in. And as always, fly what you can afford to lose.
