I have a level 20 wizard, about to TR. I had a lot of fun playing this character, much more fun that I had playing any of my melee toons. There were a lot of things about Wizard I didnt understand though, which resulted in a slightly gimped charatcer once I was at 20. My AOE spells dont do as much damage as my pugs would like, and others, (dancing ball, energy drain etc.) usually fail, even with higher rolls. Id like to TR into a wizard that is great at weakening enemies with various spells that lower their levels, stats, saves etc. and still be able to put up a respectable fire wall or ice storm. What feats, skills, abilities, enhancements, gear should I choose to make this happen. I also really like using necrostic ray, so How can I make that do tons of damage?
Also, I can't even remotely understand what the heighten spell metamagic feat does (Yes I have read the wiki, makes no sense to me). Can someone explain to me in laymans terms what the heck it does? I also dont entirely understand empower and maximize.
Any other tips for making a respectable wizard would be appreciated.
