And to be able to battle NPC’s found in those sites.
Are you aware that a lot of WH sites don’t have any npc’s ? Have a look at https://wiki.eveuniversity.org/Relic_and_data_sites . I cleared 4 in a C3 today, made nearly 100 million isk. If you go that route, I’d choose an Astero with scanning modules fitted, hacking modules in cargo, and a Mobile Depot so you can swap between the two.
Yeah i know
A Fleet …
Seriously … take a look here https://wiki.eveuniversity.org/Wormhole_sites and you can see the waves of ships they will send at you. These are not sites for single explorers, rather teams ready for PvE.
That depends entirely on what class of WH you’re exploring in. And as the OP is finding Pirate Data/Relic sites it’s fair to assume he’s in low class WHs, where it is completely possible to solo the sleeper data/relic sites.
Passive Drake can do it, as can most active tanked T3s (proteus may be not so much, though haven’t tried). Have also used a Stratios with mixed success. Just be aware of the triggers to ensure the single ship doesn’t get overwhelmed. I will say though that the relic/data loot is almost not worth bothering with, most of the sites value comes from the sleeper loot/salvage.
Edit: Eve Survival is a good place to check over the site prior to running it, for C3 sites:
I run the c3 stuff in a Tengu. Easy to refit for whatever you need it to do.
Drake for c1 and c2, will do the job; there are other ships you can use of course but i dont think any are as effective as the drake tbvh both for cost, ease of training and general use and malleability.
