A factotum (3.5e dungeonscape) can "fake" casting spell with the ability arcane dilettante.
This allows to spend inspiration points to "cast" spells from the sorcerer/wizard spell list as spell-like ability.
The limitations are three fold :
- number of spell per day capped by the aforementioned ability advancement (up to 8 at level 20)
- max spell level also capped (up to 7th at level 18
- only one spell of the maximum level (the rest may be distributed however the player likes)
The question is : is there any proposition to circumvent (at least partially) these limitations or to increase the limit ?
