With this knowledge I'd say this is a world-altering spell that would significantly impact a campaign. I can easily see legions of guards all with permanent spells upon them (detect magic, detect invisibility, etc). Yeah, you have to have a spellcaster willing to pay the price, but for the low level spells this is going to be cheap.Originally Posted by Fax Celestis
I don't have my books in front of me, but some spells have a "until used or x number of rounds, whichever comes sooner" type duration, would you be able to effect those with TP? If so, that would then change the duration to "untill used" right?
