I would like to ask you guys about something that got me confused.
So, there are general Vim spells like Maintaining the Demanding Spell, which can affect other spells. The level of the spell they can affect depends on the level of the "metamagic" spell. By the letter of the rules, this should mean that, say, a level 25 Maintaining the Demanding Spell would support a level 25 spell, but it's weird because some of the levels go into Duration, Range and Target, not into the base effect, which would be the spell support thing. If we take that into account, a level 25 Maintaining the Demanding Spell would only support a spell up to level 15. So... which is it?
