ToME: the Tales of Maj'Eyal

Shield wall stays active when you switch to your secondary weapon - even if its a two hander. At least it appears to... the armor value stays the same even though the shield is no longer equipped. Pretty sweet but unintended i'd imagine.

Correction: Both armor and defence are reduced when switching the secondary 2hander, but they are still way higher than it is without shield wall active and using the same 2hander.
