More Halcyon Spellcaster questions

[Nik Gervae]

The feats that grant halcyon spells specify that they must be common halcyon spells, but, after you take the feat, can you use Learn a Spell to replace one with a halsyon spell that's uncommon?

The introduction to halcyon spells says that if you are a prepared caster, then your halcyon spells are treated the same way: they go in your spellbook/list, but then under the feats, it says you can use your halcyon spell slots to spontaneously cast your halcyon spells. Well, wizards and druids don't add leveled spells to their lists, so does that mean you can spontaneously cast a heightened heal (for example) at whatever level you want? Because the same introduction to halcyon spells says you can't designate them as signature spells—but wizards don't even have signature spells. Or are a prepared caster's known halcyon spells actually fixed at a level, in contradiction to the general description of halcyon spells?

I do not think you can use Learn a Spell for halcyon spells, because "You don’t gain new halcyon spells via the normal means you typically use to gain spells".

However, there is no rarity restriction in the rules for swapping halcyon spells : "Each time you gain a level and learn new spells, and each time you gain a halcyon feat, you can swap out one of your old halcyon spells for a different halcyon spell of the same level; this is in addition to any swapping from your class, such as via a sorcerer’s spell repertoire class feature. You can also swap out halcyon spells by retraining during downtime."

So I guess that is the way to get not-common halcyon spells.

For the second question, I believe that, as a prepared (and non-Spontaneous) caster, you know your halcyon spells at all levels as far as heightening is concerned, and thus can cast it heightened spontaneously too.

But I agree that the description of halcyon spells for spontaneous casters is not clear on whether you have to choose them at a specific level or you know them at all levels automatically.

Note that I believe the restriction about halcyon spells not being available to choose as signature spells is to make sure that a spontaneous caster will not cast them at a higher level than their highest halcyon slot.

That makes a great deal of sense. Thank you for all your answers!

Quote:

Each time you cast a halcyon spell, decide whether it is an arcane or primal spell. You can’t heighten a halcyon spell beyond your maximum spell level of halcyon spell, even if you have higher-level spell slots, and you can’t select a halcyon spell as a signature spell.

A character can't choose a halcyon spell as a signature spell but for example, if a character has a halcyon spell heal level 1, the character can take the heightened version of heal 5th level with a a 5th-level halcyon spell slot, is it right ?
