I remember having some fun with a
Skeleton Marauder i won with, though it was in normal mode .
I wonder how marauders can do in nightmare.
Though i'm not sure which race i'll use, the skeleton was awesome, but i have read often that the undead starting place is a horrible hell in nightmare.
Hopefully the Shalore route will help
edit
I went with a Shalore Marauder, and for the fun of it, Insane difficulty.
Of course this time i immediately exited the scintillating cave and went to trollmire.
I press autoexplore, and i'm shot with poison by giant venus flytrap.
I go back to safety of a corner and notice my health going down very fast. my character has no wild infusion (to my surprise, instead i have shield and phase rune) so i waited and the poison disappeared when i was at 1 of health !
wow, that's starting greatly
edit 2 : hilarious, i managed to defeat 2 trolls and both of the fights have been boss-level (and those weren't even rare, just regular monsters) type of fight, with lots of pillar dancing (tree dancing in that case) , hitting while i'm protected and with my skills back, then pillar dance more etc...
Then i ran into a wolf, and unfortunately a rare that shot me with some beam to death before i could do anything else.
Lisildara the bee swarm hits Terriblos for 71 mind damage.
Insane difficulty indeed
let's focus more on nightmare then
