ok, so this time I try the smarter Lich mod...and it seems to have no way to dispell their invisible/or half visible/in sanciturary state. That means that we cannot cast spell to dispell his spell/combat protection. and he's having fun time stop-ADHWs-FoDs...us and our summons, while it cannot be hurt. I managed to beat the one in Underdark, elemental lich in the bridge, and the one in City Gate; but it's quite frustrating that I just have to have my party survive and wait until those liches run out their spells (at least they don't have unlimited spells

) This is really an unstatisfied way to beat liches. How do you old hands beat them? how to dispell their protection?
Turning ture Sight on doesn't really do anything, they're partially visible but they're in sancituary. Also, IIRC, liches are not affected by lvl 1- lvl 5 spells, and so remove magic or dispell magic simply won't work. How to cast spells on them????
