i'm also wondering IF solasta feats will be available for bg3? love the follow up attack. i find myself picking up feats rather than ASI as suggested by many guides though. solasta is really nice since they gave us factions that sells stuffs can increase those stats so makes more sense to pick feats that has abilities.
That is correct; Spirit Guardians only causes halved movement speed. It doesn't have the full effects of the spell "Slow."

Solasta feats almost certainly will not be available for BG3. Solasta wasn't able to get the full 5e license, which means they didn't have access to any D&D 5e feats besides "grappler." So Tactical Adventures had to create their own homebrew feats.

Larian, on the other hand, does have full access to the 5e license. So they'll almost certainly use mainly 5e-published feats, with some (probably small) number of homebrewed - but still different than Solasta's - feats.
