That's precisely what it means. You can dump a spell slot to instead cast an SNA of the appropriate level. Per the SRD:(Emphasis added.)Originally Posted by Druid, Spontaneous Casting
As an aside, the general rule with feats on a Druid is that you only need three:
- Natural Spell, to use spells while Wild Shaping. It's practically a feat tax.
- One summon augment spell (such as Greenbound Summoning) to make your summons meatier.
- One Wild Shape augment spell (such as Frozen Wild Shape for Cryohydra) to make your Wild Shape even more versatile than it already is. And it's pretty darn versatile.
As for that spell recall thing, a quick search turned up several options:Don't think any of those work for you, unless you plan to play an Aerenal Elf and can gain the Deathless domain as a Druid.
- Retrieve Spell (CC): Burn TU uses to recall a spell. Only works for spells derived from classes that use TU.
- Chaotic Spell Recall (FCI): 1/day recall one spell with the [Chaotic] descriptor you've already cast. Swift action. Requires Abyssal Heritor feats.
- Call of the Undying (RoE): 1/day recall one spell you've already cast. Swift action. Requires Elf, Aerenal region, access to Deathless domain.
But since I've mentioned RoE, and you say you're good with Races books, are you set on a Dragonborn Mongrelfolk? If not, consider the Shifter, also from RoE. It has two really good racial substitution levels in Druid (the third one is rubbish). And if you plan to indulge in some minionmancy, there are few Druid PrCs better for the task than Moonspeaker.
