Hi there I am at the part of the quest where I have to go up the hill to try and kill Legate Lanius and I have full health and can only get him down a couple bars before I get absolutely destroyed by him, my barter and speech skills aren't high enough to make him come to a peaceful agreement, HELP PLEASE?!
Here is how I managed to beat him. My speech skill isn't high enough either.
I laid a path of frag mines. You have to mark where it goes into speech mode and start laying them down just before there and back up as you lay out all the mines you have...Frag/Plasma. I kicked it off with a plasma grenade from the rock on the other side of the path.
Bug/Glitch? I purposely overlapped mines, so when one went, they all went at the "T" junction. I also at that time, hit the Legate with another plasma grenade -- if I wasn't hitting him, then he was going to be the new "Burning Man" while I took him down. Oddly, the combination of the mines, and the grenade, launched him in the air and he came down....came down dead hard. I got lucky there, and it was kinda cool to watch him launch up like a roman candle
His buddies took out Cass and I went through nearly all my chems, but the Multi-plas and I finished them, and the belated reinforcements.
My advice, look in your inventory and see what you have that may work for you. I think bottlecap mines would be ftw, if I had made any.
Took me over 10 tries to get it.
And now it appears that the door to his tent is bugged because of how he died? I get "That door is locked from the other side"...it is a bloody tent, not freakin ft knox.
