Yeah, guardian being useless needs to be tripple underlined and bolded in red in the OP
I just sifted through a list of mage pawns, found only 4 with the right affinities and spells and ALL of them were guardians
Imo if you find a pawn with the right spells and decent stats (1500+ magic or str) in BBI then just stick with it, even if you outlevel it by ten levels, at least it'll won't be sitting there doing NOTHING and at least it'll have learned the weaknesses of enemies you've already beaten.
Changing your pawn often in BBI is the biggest mistake I've made.
Im at those red ethereal glob things after the second shortcut now and the sorc pawn who was guardian refused to attack it, the mage pawn who wasn't at least put holy affinity on himself then PAINFULLY slowly killed them.
3 of the giant dogs spawned while I was already fighting two of those ethereal things so I ended up just teleporting out.
I think I'lll clear the area right before the second shortcut a few times to get some checks and levels (leveling up incredibly fast now) before I try again.
How many days do you have to sleep to get the chests to respawn?
