if your going to adonis catacombs, the walls LOS is a real problem. basically, if your in a hallway, anything on your minimap will be aggrod & come to you. the only way to do it is to pull mobs into a dead end with nothing near it (ie the start) or use the stairways & pull into there.
the mobs in adonis catacombs are lots easier than those in penumbra. theres much less HP on the adonis ones, & they hit for a bit less. if your after tier 2, & have a good team though, penumbra might be the way to gi to try & kill everything, just because pulling is so much more reliable there. if one team can handle adonis catacombs, then you'll likely be able to handle penumbra catacombs aswell just because you'll only be fighting one mob at a time
fyi, in adonis catacombs last night we had myself, madspin, caid, ryons, ailish (fp doc). we could take on one mob at a time very easily, we took 4 at one point. one boss mob & one add had us though unfortunately. in penumbra a similar team managed to kill quite successfuly with no doc (think we had MA), but only because me & madspin were able to bounce aggro through TMS. if you have 2 soldiers to do this with, i'd highly recomend this, as it's very hard for a doc using pre SL heals to keep up with the damage these things churn out without using CH. bring an MP for mezz pet to slow it down or someone to chain cast layers & you may have more success.
btw, feel free to ask me to come help aswell. i've got a few pieces to make my chest part, but i still need parts.
good luck
