scratch thugs, they might tear you into itty bitty shreds. Sand sprites would be a good option, or possibly even blood wolves. Not certain on blood wolves, been a long while since I"ve trained on them. Once you hit about 115-120 in evasion, depending on your reflex, I'd say steeds in Shard. Sand sprites will move weapons though. Don't do like I have done and let weapons fall nearly 60 ranks behind backstab.
I'm learning that lesson now tryin to play catch up. Kicking myself for it. Going on 85th circle, and I had some bad habits of only stealth training. Worked great up to low 360's in stealth. And near 320 in backstab. But having my highest weapon nearly 60 ranks behind my backstab, yeah, I'm payin for it now. But it gives me the chance to train parry at about 15 ranks behind my highest weapon. So I've got something going.
Bipeds are bad for evasion learning in general. Thats for certain. I don't remember what Arbs teach to, but they are in the Haven area. Near ogres. Not dusk ogres, the others. Once you get about another 15 ranks in weapons, there's always vines and creepers. Or even Silver leuc's out on the islands (Ratha) once you get to about 90's in weapons, and 100's in evasion. Granted, again I don't remember what they teach to. But they teach higher than sand sprites. And if you cap out on them, there's always Swains (which are in town). And spawn 3 per character. Which are over silver leucro's.
Heh, rackin my brain here. If I think of anymore critters, I'll throw in another post.
