Bring someone with tornado?
In the beginning it will be hard no matter what you do.
1 map is hard no matter what, and sometimes half of second map is too. But once you reach level 13
you just bulldoze everything no matter where you have put your points.
Just remember dont take twohanded if you plan on taking a tennebrium weapon on because then those points will just be wasted. learned that the hard way sadly
And take dust devil in the beginning because you cant buy that in the game.
Thanks for the tips! I cannot bring 'someone with Tornado' as I have two Lone Wolves.

I've already taken Dust Devil when I started the game, I'm currently level 9. Whirlwind is much more powerful though, however while I still have free skill slots I'm using both.

I've no idea what Tenebrium weapon is (in case you're going to explain don't spoil too much, please), but you can just respec your points, can't you?
Nice screenshots, thanks! Would be interesting to also have a look at the undead summons.
