I noticed the boosters stacked, I didn't realize the spells did
I also didn't notice that raising my magic skills increased damage/effectiveness... but also cost
oops! Had to level up a bit to remedy that issue
I've got a few summons now, but I need to track down the Necro skill trainer (I think I stumbled across some hints leading to him already)
Anyone know if Hard mode has any effect other than the lack of auto-rez? I do know the first glacial orcs I ran into one shotted me with an arrow

I was playing the demo on normal, at first it seemed like the monsters were hitting harder and were tougher, but I don't know if that's actually the case.
lockpicking rules incidently, I went pilfering in town and robbed every home I could find, walked out with some monster 2h sword and a pile of spirit damage enhancers. it works perfectly with the spells I'm using, as I can drop a ring of fire, then cleave creatures stuck inside the flames, since they usually try to avoid getting hit by the fire more than a few times, which bunches them up nicely
I also like how you periodically get skill points for lockpicking/stealing/killing/etc
archery seems pointless, given how long it takes to load a shot, unless you get giant explosive arrows later or something.
traps were excellent - before I got the magic rolling, I went and planted about 20 traps outside a giant bandit camp, went in and pissed them off, then ran away and watched a recreation of a bad war movie as the minefield detonated
edit: one last thought before sleep - oblivion killer in the thread title just invites trolling. this game is an action-rpg/monster basher/loot collector/ridiculous damage numbers game, it feels nothing like oblivion, and a lot more like diablo in 3d, albiet with somewhat more quests, a giant ass world, and some hilariously translated and voiced story
