I was considering this trait for a mesmerist, cause a single skill point is boring(and a lot of the other race's options for trade out are equally 'meh'), and this trait sounds fairly interesting. A few low level druids spells when you are in a specfic type of terrain, plus some class skills and low light vision. Fair enough.
While looking through the level 1 druid spell list though, I noticed that Recharge Innate Magic was a level 1 spell valid for this racial trait.
So the question is this: As a racial SLA, does Recharge Innate Magic recharge itself? Or does it count as 'fully charged' when cast, thus not getting included in the spells recharged?
This of course, has practical applications since it recharges the three level 0 spells as well. Effectively, it gives you three cantrips. Which would be interesting on cha friendly classes without cantrips, such as swashbuckler or paladin (heck, pratically every paladin is already connected to fey magic since they are fey foundlings).
Now, for a balance perspective, I will note that there are some rather large caveats for this. The first would be the restriction of use to specific terrains. Whether that is an issue varies with campaign, of course (if you are in a campaign almost entirely underground or in an urban area, this is not an issue). Next, there is the fact that you can only have one charge for theses spells at a time (which means that there may be two rounds between uses, since you have to recharge).
The last thing to note is that the circumstances of this question are also very rare- there are not very many racial traits that allow you to have a level 1 spell and then still get other level 1 and level 0 spells. So, outside of the use of fey magic (which, as previously stated, has some big caveats with the terrain), I cannot think of anything that can actually use this option (and if there are, they are VERY specific).
Seems unintended, but legit. Not OP.
