There were 2 new rules.. make sure they are FALSE.. since I am sure EZ is scaled correctly with them intended to be off..
Here are the rules if they do not exist in the database... by default.. the Spell one is true and the item one is false.
So if the rules are not there.. NPC spells will scale crazily if they have spell focuses on.
INSERT INTO `rule_values` VALUES (1, 'Spells:NPC_UseFocusFromSpells', 'false', 'Allow npcs to use most spell buff derived focus effects.');
INSERT INTO `rule_values` VALUES (1, 'Spells:NPC_UseFocusFromItems', 'false', 'Allow npcs to use most item derived focus effects.');
