Yeah, it is. I like the spell list except magic jar. How about we keep Reach Spell, give it a reach vampiric touch at 5th-level, and swap out Repeat Spell and Silent Spell with Spell Focus (enchantment) and Greater Spell Focus (enchantment)?
The problem is it can just cast
spectral hand and get a 230 foot reach on all its touch spells for the duration of the hand (13 minutes), with a +2 bonus on its attack rolls to boot.
Indeed, it's such a useful spell for the spectral wizard I'd consider having it prepare the spell twice or giving it a
wand of spectral hand.
How about Craft Wand, Spell Focus (enchantment) and Greater Spell Focus (enchantment) instead of Still, Reach and Repeat Spell, give it a
wand of spectral hand and swap the
spectral hand for
touch of idiocy?
