Optimized Hold Person/Hold Monster - Enchantments in general - is incredibly powerful, even if situational. It becomes incredibly apparent especially if you have the Serpentine or Undead Bloodline(s), which allows you to affect animals/magical beasts/monstrous humanoids or undead humanoids, respectively, or the Fey Bloodline, which is far more restrictive, but adds a solid +2 DC.
As good an excuse to dip Sorcerer or Eldritch Scion (which gets Bloodline Arcana in PF:K, IIRC) as a Bard as any. I wish there was a bard archetype that got a bloodline.
now that this is going to be made for sure, whos gonna make a Starfinder game?
I maintain that it would not work well in the PF:K format, but that it'd actually be a great game for something made by Larian. The setting is pretty gonzo, and the Larian humor wouldn't be out of place. And just like in Larian games, the gearing threadmill is absolutely shit, and would be improved with randomization of weapons and armor anyway. The free-movement turn-based 3D would work well with the more modern, sci-fi feel, and fairly easily generated large areas would lend itself to the primarily ranged combat, as opposed to the by necessity fairly small hand-crafted areas of a game like PF:K.
I mean, Larian won't do it, of course, because they're busy sodomizing Baldur's Gate's corpse like a bunch of gay-for-pay necrophiles, and Paizo has a deal with Owlcat, not Larian, and Hasbro would likely not want Larian working with Paizo on anything, either, for "political" reasons of hunting in the same market. I have no doubt that Owlcat could make a good version of it, though - maybe even a more competent version than Paizo themselves, given Owlcat's apparent love for 3.X - but it'd have to be very different from their Pathfinder games and I'd honestly prefer to see them keep working on Pathfinder games and just keep driving home an evolutionary approach to game serialization. Starfinder wouldn't fit in there at all - but Iron Gods might, which I guess would give them a lot of potential assets to use in a Starfinder game down the line, who knows?
