Correct me if I am wrong, but when SE releases info on new abilities/spells that are achieved through merits, don't they mention they are with the info? I thought they usually did, but I may have forgotten. Also, as for the -ga/-ra thing, Garuda gets Hastega, which seems to not follow any of the normal patterns (possibly because it's a BP).
Sidenote: speculations on what the new SMN ability actually does? I'm a little confused by the description, lol.
Use light avatar and it gives you mp is what i understand
