Weapon Crystals

Weapon Crystals are crystals, that go to weapon crystal slots. A weapon can have four crystal slots. Crystals can be obtained from various methods, including Crystal Merchants, other players via direct trade or via the Brokerage, or enemy drops. Vanguard Initiative merchant sells Niveot crystals for Vanguard credits.

Since from TERA early days crystals simplified. First we saw introduction of crystals affecting all types of monsters (bosses, normal monster and minions) and later even all old crystals were changed to affect all types of monsters.

Recommended crystals
Standard damage dealing build in TERA maximizes crit rate and crit power. Crit rate is achieved with rings, earrings, necklace mainly. Crit power comes mainly from Prime Battle Solution and weapon crystals.

For melee offense classes standard crystals are Bitter, Savage, Focused and Pounding. For ranged offense classes Spiteful, Savage, Focused and Pounding. If crit rate is low (< 230) switch Pounding for Carving.

For tanks standard crystals are Wrathful, Focused, Pounding, Pounding. Again, Pounding can be switched for Carving. If tanking for better geared players Threatening might be needed.

Priests post-apex have no problems with mana and can use Spiteful meant for ranged offense crystals if more damage is desired. In addition Carving can be used, since heals have chance to crit too. Healers usually prefer Swift to maximize speed in combat.

Mystics, however have serious problems with mana. Brilliant crystals are recommended. Mystic usually uses Swift due low speed and Carving can be used too.

PVP
For PVP situation is more complicated. For maximizing damage use Savage, Forceful and Carving. Other crystals for damage dealing are those that give bonuses when knocking down opponent: Cruel, Brutal or Virulent. Also movement speed in combat is popular with Swift. Tanks have no different crystals to use apart other classes.

Healers generally go for movement speed, Carving for crit heals. Depending on battlefield using 3&times;Brilliant + Salivating might be necessary.

Well, January 2019 new PVP gear got rid of crystals. If battleground allows accessories crystals, use PVP defense Zyrks. PVP defense crystals have more stats than PVP attack crystals.

List of Weapon Crystal Prefixes and Meanings
The following is a list of the prefixes of the weapon crystals found in the game. Each of these crystals can be found in the different levels of crystals (Rhomb, Cabochan, Hexage, Pentant, Concach, Crux, and Niveot) and can also be common or uncommon varieties. Hence, the list below does not list the numeric value for each possible crystal.

(Note: Acrimonious, Backbiting, Carving, Domineering, Hunter's, Mutinous, and Squelching crystals are not available from the crystal merchants.) Monster classification seems to be removed from game. Any crystal that refers to bosses, normal monsters or minions should work against all types of monsters.
