Triadspell

[aboyd]

It is instanteous so you can get all of your 3rd and lower spells to be used 3 times/day before battle if you have the time.

Hmm. OK. That finally makes some sense. Each day when a wizard prepares spells, he/she does not have to re-prepare any slots that are just fine, and because of that, any spell that has been triadspelled would remain so. Thus, you could spend many days making all your lower spell slots triple, and thus make yourself more like a poor man's warlock. Got it.

That is useful, so I'll reconsider my opinion that triadspell sucks.

But now we come to the difficult part. Explain what happens when a spellthief interacts with this. The flavor text implies that the spell isn't split into three slots, but instead remains in just one slot, but now is persistent though 3 uses. So if a spellthief steals that slot, do they get all three? Why or why not?

Well I'dd say there are three options:

1- The spellthief steals the slot gaining all 3 uses.
2- The spellthief steals the slot gaining 1 use, you lose the other two castings.
3- The spellthief steals the slot gaining 1 use, you still have two uses left.

I'dd actually rule for the third option by saying that the spellthief steals the 'spell energy' of that spell. The description of triadspell says: the altered spell functions normally[...] as if you were casting three seperate spells. I'dd say you just made that one slot have 3 times the spell energy.
But I guess it's up to your DM cause this is not something I think you can hard rule.
