"Tundra Discipline" spell does not work correctly with discipline abilites. "Tundra Discipline" spell grants basic attack frost and with that basic attack the discipline abilities do not work as they should. For example with "Ferren Master" if he had "Tundra Discipline" spell just put on him. "Basic attack - frost" should work as a basic attack and therefore discipline abilities like "Sundering Discipline" are supposed to activate but dont. Thanks for reading.
