Finally! After almost a month, I was able to complete my archeology training for a return trip to the Takhmal Temple site in the Labyrinth.
When the temple site has a full spawn, it is;
4 - Scramming Frigates
9 - Cruisers
-- 3 - Thorax'
-- 3 - Mallers
-- 3 - Moas
2 - Battleships
The groups spawn in different intervals. The cruisers spawn in their respective groups of 3, the frigs all spawn together, and the battleships spawn together. So if you're in a group, managing aggro can be a bit of a challenge. Whoever has the best tank can hold the aggro from the cruisers and battleships, and the group can repeatedly kill the frigs, or if the group has enough DPS then the entire spawn can be wiped quickly enough.
I'm still unclear on one part though. I didn't find any of the takhmal skillbooks in the temple site. It was my understanding that this was where they would be found. I need to do a bit of research to find out the frequency of high value drops in the temple.
All in all, we made around 20mil with the artifacts and bounties between the three of us, in just over 2hrs.
