Type 5 augmentations

Type 5 (General: Multiple Stat) are augmentations that were released with The Broken Mirror expansion. Type 5 augs contain bonuses to heroic statistics. They may be obtained in The Broken Mirror and later expansions from mob drops and purchased with various alternate currency.

Type 5 used to be Type 5 (Weapon: Elem Damage), augs that only fit into Lost Dungeons of Norrath weapons. These older augs still exist but do not fit into the new General: Multiple Stat Type 5 slots on newer items.
