fox and badger can be killed quite easily with 25ua on foot in my experience, there's no reason to take damage if you just keep renewing your defences but I suppose that is where agi comes in
Boars arent too hard if you remember to use red defence and not attack into tusk romp, I would say about 50ua, also deer have super high agi but very low hp so using chop with sword makes deer killing a lot easier
