So I started playing through neverwinter nights, through the swordflight module, and decided to go for a pure wizard. It's actually kinda annoying, but regardless, I've reached level 21 but am a bit confused, I think. So I get tier 10 spells, but you have to burn an entire feat for it, in addition to there only being a handful of them, so is this it? There's pretty much no way to improve at this point? I've been using delayed fireball and issac's greater magic missles spells as my main damage, I've had them empowered for a while now and the enemies are starting to get pretty spongy, I've tried mixing it up with some other damagy spells like "weird" that insta kills them if they fail a saving throw, or some lava spell, but what will happen in the next chapter? When the enemies get really tanky? What will I do then? Is there a way to increase damage more by taking some special feats or are there some special wizard items?
