This was reported on the "other things" forum over a year ago, but it should probably be here.
Wiki says that Necro specialist wizards with GSF Necro get this bonus:
Summons gain 15 + (Wizard Level/2) Spell Resistance
From what I can tell, this is not working. It's not on the Summon character sheet, and I've never seen them resist anything.
Can this get fixed? It would be a nice perk for the handful of necro spec wizards that actually exist.
