Yes ! Victory !
Iunytar the Skeleton Marauder just annihilated all his enemies and won the game !
Out of the early game that can be very hard or normal depending on what kind of dagger you're using, the Marauder increase in power when improving the skills and unlocking some trees during the progression of the campaign will make him incredibly strong .
The Marauders can be as scary strong as an Oozemancer, and i didn't even took the antimagic/fungus part (undead can't join Zigur) i think that's the 1st time i dealt so much damage (more than 4000 ) in 1 turn to Elandar with a single use of Flurry :
It looks like beating the bosses give you enough XP to get to level 50, as my skeleton marauder after completing everything and running a few farportal was only level 46 when it was time to get into the Sanctum.
I took the stone alchemy tree from an escort in early game, so i could increase Imbue Item to 5 and so get the Crafty Hands prodigy to be able to imbue 3 of my worn items instead of only 1 for the endgame, it really helped to make my marauder better.
On the good advice from the ToME4 board, i used a moonstone on the belt (+60 to stun/freeze immunity) allowing me to free the 2 rings slots for more usefull bonus (i was using +30% stun resist rings on both, as stun is the worst thing to be affected by when you use an undead that can't then use an infusion to get rid of it) and used 2 diamonds on the other 2 items (adding +5 to all stats for each items) , giving some impressive results in combination to the already nice item was using.
Giant Leap proved to be the best prodigy i could take for that Marauder, great damage if used offensively with the multi-hits of a marauder, and great survival asset if used to retreat a lethal situation.
All in all, i had a lot of fun with that character.
