I use this for all T1-4 Sites, except the Dark ones (which I pretty much ignore above T1):
[Ishtar, Abyssal]
Corelum B-Type Medium Armor Repairer
Federation Navy Drone Damage Amplifier
Assault Damage Control II
Core X-Type Armor Explosive Hardener
Federation Navy Drone Damage Amplifier
Corelum B-Type Medium Armor Repairer
10MN Afterburner II
Republic Fleet Large Cap Battery
Medium Capacitor Booster II, Navy Cap Booster 800
Omnidirectional Tracking Link II
150mm Railgun II, Federation Navy Antimatter Charge S
150mm Railgun II, Federation Navy Antimatter Charge S
150mm Railgun II, Federation Navy Antimatter Charge S
150mm Railgun II, Federation Navy Antimatter Charge S
Medium Anti-EM Pump II
Medium Auxiliary Nano Pump II
Clone has Mid-grade Slave implants
Hardwirings: TA-705, MH-805 (historically), SS-905, HG-1005 - there might be better suggestions for that.
Armor Reps may be upgraded to Centum/Corpum for more safety.
The Slaves may be replaced by Asklepians, but I like the little more buffer (~2,8k armor instead of 2k).
Cap booster may be rarely necessary, but when you need it you want to have it.
T4 Electric + Exotic are pretty easy, T4 Gamma + Firestorm can be demanding when it comes to Vedmak + Damavik Spawn (non-Vila), but it’s still doable. For my experience this fit also delivers enough DPS for the T4 Firestorm sites, but I am keeping away from them if I have other T4 filaments.
