Strike Augments

Strike augments are augments that can be placed in certain weapons which will add a damaging proc to your weapons. They are obtained through the Crafter's Guild by combining Superior Lightstones, ores purchased from the Crafter's Guild merchant, and essences

Icestrikes are the strike aug with the least damage, but they also cost the least to create.
Icestrikes are usable by the following classes: Cleric - Druid - Shaman - Wizard - Enchanter = Necromancer

Firestrike

Firestrike augs are much more damaging than Icestrike augs, but less than Ninjastrikes - they cost more than Icestrikes to make.
Firestrikes are usable by the following classes (including all icestrike classes): Paladin - Berserker - Shadow Knight - Beastlord

Ninjastrike

Ninjastrikes are the most costly, and most damaging strike augs, and are only usable by pure DPS classes.
