Sorry if the topic is already covered somewhere. What's good skill trees for dedicated, pure wizard character? Promethean magic does wonders, drop it into fighter build and you get an awesome reaver having nor much problems with zoos. Summons are boring as a main source of damage. Thaumite Swarm, Fleshbore and Golden Ratio tend to fail on monsters with AA/resists (didn't play much with those but djinns didn't take much damage from either of those) - maybe it's just me? Psionics are awesome for a fighter-mage (nerve staple is awesome), but not so much for a wizard. Trees giving buffs to melee are wasted on wizards. So - if you would make a non-melee wizard, what trees/skills would you take to actually kill enemies?
Astrology, Promethean Magic. Mathemagic is heavy on single enemy spells, recursive Curse is ok but the main use is teleportation and then you have Alchemy(Brimstone flasks) or Wandcrafting for other miscellaneous spell-based effects. Necronomics is great for nuking, Fleshsmithing has a pseudo-nuke and Viking Magic has a bunch of neat spells as well. Lastly Mathemagic and Golemancy are more on the utility side, Unliving Wall and Teleport effects.
I would say Necronomiconomics all the way, as long as you can find early necro resist (from gear or Astrology, very easy now that Little Black Books are ubiquitous), or spare a few levels until the tree starts generating its own. Nightmare Curse is an efficient named monster disabler, and deals good early-game damage (though I don't know if it's affected by the new DoT spell bug like Recursive Curse and its like). Pact of Fleeting Life = never fear melee again, even with the squishiest wizard. Entire builds have been created around that one spell. Eldritch Inhabitation is costly but does wonderful single-target damage, and Tenebrous Rift is the best zoo-killer out there. Promethean aside, Viking Magic would be my second choice. Arctic Vortex allegedly has the best or second-best DoT in the game (again, DoT bug notwithstanding), while the capstone Thor's Fulminaric Bolt does lots of single-target damage, respectable AoE and has a cost that scales exceptionally well for a top-of-the range spell.
