Can summoned creature cast spell at lower level?

[x x 806]

If a summoned creature cast a spell of equal level or higher than the spell that summoned it the spell fizzle. Could the creature cast it at lower level so the spell work?

By example with a summon lesser servitor at level 2:

- A qasit can cast detect alignment at level 2 but it is a level 1 spell that would work if cast at level 1

- A Shaukeen with constant magic aura at the 3rd level. Magic aura is a spell of level 1 so can the Shaukeen magic aura work at the level instead of the level indicated into the creature stats?

IIRC Innate spells are always cast at the level given.

So, no.

Innate spell specify that you cannot heighten them and innate cantrip are heighten like normal cantrips and that you can cast them at higher spell level that you normally cannot cast but not that you cast them at the level given. The rule must be somewhere else

Unfortunately, while there's no rule saying you can't undercast, there's also no rule allowing it, which one kinda needs in games like PF2.

One example to note is that the Balor has Dimensional Dervish, so they can cast Dimension Door with one action. They cast Dim Door as a 5th level/rank spell, at will (or 10th, 1/day). If cast at 5th, the caster becomes immune to Dim Door for an hour, which would make Dimensional Dervish only usable 1/hour, which seems too discordant to be true (at least for a level 20 creature's ability).

Of course, the Balor entry's more likely a hiccup than a comment on undercasting, so it's not evidence so much as in need of GM adjudication for itself. Personally, I'd allow undercasting, especially due to weird interactions with Wild Shape, Light, etc., but note that there's been much argument about this with no consensus due to different GMing approaches.

As for the Shaukeen, it's not casting Magic Aura, so the spell's active as the Summoned entry describes only how casting interferes/ends the Summon. That said, I would disallow shenanigans that try to bypass the cap, such as giving the summoned creature all one's items to get the benefits as if having cast multiple similar level/rank spells.
