Hey, nice work.
Thargoid Scouts do offer some bonuses, beyond the pay. First, they are easy kills. Second, they are all rated Elite rank. This means your combat rank will increase at an accelerated rate, compared to fighting NPCs.
For the Caustic damage, there are two options. One is a Decontamination Limpet Controller, and a small cargo rack for a few limpets. When launched, these limpets will remove the Thargoid caustic goo from your hull. The other option is to heat your ship above 150% for a second or two. Some ships this is easier than others. This heat will burn the Thargoid good off your hull, but you may suffer a bit of heat damage in the process.
I use the Decontamination limpets, they are really handy.
Trying to remember, but it’s possible that the Decontamination Limpet Controllers are only available at Surface Military bases. I may be wrong, but if you have trouble finding them anywhere else, give that a shot.
Finally, take a look at the Aegis mega-ship “Vanguard” in Aongi, just a jump or two from Dalfur. They offer Scout kill missions, once you are decently on good reputation terms with the factions, the pay is sometimes more than $1,000,000 for killing 8 to 12 scouts. This mega-ship moves every week or so, as the Thargoid threat advances. The ship lists it’s next destination on their news entry, for a few days ahead of the jump.
I’m in Dalfur, too, BTW. Killed over 200 Scouts in the last couple of weeks. The furballs can get pretty intense sometimes (I’ve bailed a couple of times with 8+ were ganged on me). They’ve been great for building some combat skills, and a nice change of pace for my Elite play.
