Near-sightedness just means mages need to be put up front.
Earth Meld has a precision bonus, so that helps a bit.
BTW, now that I noticed those updates you made to your previous posts, some comments. (It might be better to have new sections in new posts if you want people to read and comment them, as every contribution appears as an unread message...)

Boots of Behemoth + Midget Masher = Bad. If you trample, you don't attack. If you don't trample, you're up against enemies your size or larger and MM does no good.

The thing with twiceborn is wicked, by the way. Got to try it. Strategic move of 3 is real benefit to Agartha with such lazy mages.
