What are good options for the last 3 levels
2 more good feats ( spell rehearsal, extend spell, persistent spell, signature spell, arcane thesis, others?)
are the alternate class feature unearthed arcana worth it?
- Chains of disbelief trades a familiar, good?
- shadow shaper trades bonus feats of 5th / 10th / 15th level which I probably will not get anyway, for hide as a class skill and will save me 4 skill points. unless someone recommends taking 2 more wizard levels, this is at least something.
-Illusion Mastery: ah the big one for me, I can see this one being worthwile if you take signature spell somewhere, but if I do no take that feat is extra spells known (basically save some gold) worth the extra spells per day?
And a question about how echoing spell interacts with earth spell and residual metamagic, is my reasoning correct:
at level 20 I raise a 0th level
Silent Image to 9th and gain +9 CL, a turn later I cast an echoing
Silent Image again raising a spell with +9 CL because of residual metamagic. This spell returns 4 hours later with -4 CL. I believe this spell will be 20 + 9 - 4 = CL 25. a net gain of 5 CL. 4 hours later I recast this Heigthened
Silent Image, applying a free echoing spell, again gaining +9 CL and losing 4CL for a return 4 hours later. This spell would be 25 + 9 - 4 for a CL30. This way I could gain a lot of CL on some of my spells
A friend of mine actually disagrees and tells me it would be (20-4) +9 = Cl 25 for the first return and (20 -4 -4) + 9= CL 21 for the second return, which actually sounds logical but would not be as cool. Since I got an headache thinking about this, could someone help me
