Go down those wormholes. You’re much more likely to find data and relic sites that haven’t been looted and on top of that they’re more valuable. Once you’re in a wormhole you can also make your way through other holes and find more sites.
Only other tip would be to make sure you’re not scanning down combat sites to 100%. As soon as you know it’s not something useful, hide it from your results and move on.
I’m assuming you’re searching for sites in high sec? Any sites that usually spawn there are picked clean pretty quickly, you’ll have a lot better luck finding sites in low or null sec. I’d recommend low because it’s quite a bit easier to avoid gatecamps, and if you stick to empty systems you’ll usually be fine.
That’s quite expensive. If that’s no problem, they do some additional dps, though. If you do 160 - 200 dps, Dagan’s shield will melt quickly.
You should orbit Dagan quite close with these weapons, so no need to load long range ammo.
Might be doable in a T1 destroyer with enough guns and enough skills trained.
(Note that my main was less than a month old but not completely new back then so had some skills trained already and had to buy blasters to replace rails on my PvE catalyst but was doable so I assume it might be doable with other T1 destroyers as well.)
I shield tanked a stabber (with the glacier skin) and eventually broke him down. It’s almost like he ran out of cap because the constant recharge just stopped. Then on the way back to new found home station I ran into a gate camp and lost my ship. At least I got what I needed from it. Thanks for the advice and tips!
