In D&D 3.5, is there any method of casting spells that fit in the lvl 0 spell slot without being limited to a number of times/day? The goal is to cast Prestigitation an unlimited amount of times/day due to the usefulness of turning people's hair hot pink. I am willing to take feats for this.
My character is at level 12 with 5 levels in factotum and 7 in chameleon.
Also, I believe I found a hint which is in some Therafirm Setting: http://therafim.wikidot.com/versatile-spellcaster
Which says: "Special: In Therafim once you gain Unlimited Cantrips you may still only sacrifice up to your normal daily allotment of cantrips to fuel this feat."
