In recent days/weeks I started getting the idea of getting 5.0 standings with all Empires. To be able to do that, I need to run all 4 Epic Arcs - which raised the questions 'Which ship?'. Since I'm not space-rich (yet), I thought of having one ship, able to do all Epic Arcs with relative ease. Currently I'm fresh after 'Syndication' (Gallente Arc), which was a walk in a park - since it might be useful to others, I decided to put this fit here on forum, together with some small guide for each Arc. Hopefully you will find it useful.

Well, challenge acceptedYou simply can't tank them with T1 battleship

Breakdown
Whoa, that's a stupid fit. Yes, it is. I will try to defend it a bit though

Low Slots:
Ballistic Control System II - for some DPS, starightforward
Co-Processor II - needed to fit the rest of stuff. Could be replaced by Meta without bigger issues.
Capacitor Flux Coil II - cap is life. This fit eats capacitor in scary amounts - so we have to provide adequate recharge
Med Slots:
Multispectrum Shield Hardener II - 2 for better measure. We need extremely huge resists, which means we have to fit a lot of hardeners here.
Pith X-Type X-Large Shield Booster - base of our tank. The most expensive part of this fit, but cannot be replaced with anything else.4
Copasetic Compact Shield Boost Amplifier - another base block of the tank. I briefly considered Deadspace modules, but for now it stays with Copas
Large Micro Jump Drive - since we cannot move at all, at least we can MJD away. It's extremely useful in several missions.
Missile Guidance Computer II - added for a bit of range, but it's unfitted for a lot of missions. Basically it's a spare slot for specific hardener.
High Slots:
'Arbalest' Rapid Heavy Missile Launcher I - rapid heavies. For several reasons - it's easier to skill into, has better application than cruise missiles, range is comparable to drone control range. You can also choose damage type (useful) and does not use capacitor (crucial).
Drone Link Augmentor I - self explanatory. We need more drone range.
Rigs:
Large Capacitor Control Circuits - cap is life, so we do everything to get the most of it
Drones:
Here I'm not set in stone yet. I took 4 Wardens, to match my missiles range, 5 Vespas to fly around if needed (rarely) and 3 Gardes, as I had no space for more. Wardens are way more useful, hance full flight (for available bandwidth).
Frigate Escape Bay:
Important - Atron, with sub-2s align and MWD.
Cargo:
Various modules needed for different missions. Currently shown set is for Gallente Arc only, as that's what I've done until that time.
Strategy
It's very simple - warp into mission, MJD away, deploy Wardens, shoot. For some missions I decided to take out MJD for extra hardener - in these missions you can warp in at 100km (make 1-person fleet to do that) and do everything the same way. This strategy is slow and innefficient, but it's safe - I could tank everything without any issues. In 'Max Tank' mode, with 4 hardeners and Damage Control, I get 1750 EHP/s - it is enough to tank almost anything that Epic Arc throws at us. You will spend some time in mission - we have lower DPS than we should, and max speed of 90m/s - but speed or efficiency were not my targets.
Skills
To fly this ship you need quite good skills - especially from Shields/Engineering/Missiles/Drones category. Base fit posted ^^ there gives me 945 EHP/s against uniform DPS, 310 DPS from missiles (incl. reload) and 216 DPS from Wardens - check if your number are in the same area. Engineering skills are needed for cap stability - with 4 hardeners this fit is stable at 30%, which means that every cycle of booster you get warning for low cap. It's tight.
Conclusion
Can this fit be better?
Sure. Feel free to improve it


Best,
Chris
