Nova

Nova is an active skill used by Sorcerers.

Nova is performed with a disc by the Sorcerer to deal damage. It creates an explosion 7m in front of sorcerer, which deals damage to enemies within 6m radius and has a chance of knockdown. It can hit multiple enemies, but damage is shared among them (as this is not AOE skill).

This skill was added in level 65 patch TERA: Fate of Arun. However, with skill revamp it's available already on level 14.

Sorcerer only takes half damage while using this skill ("super armor"), and has a greatly increased resistance to knockdown and stagger. You can usually safely "tank" some damage with this skill.

Nova is especially important as combo skill: casting it increases crit factor 2.5 times (calculated from base value of 50, this means +75 more crit, with best glyph) for 4 seconds. Generally it's used with Meteor Strike like this: On later patches Meteor Strike casting finishes far before meteor hits. Therefore it's possible to reverse Meteor Strike and Nova, and Nova effect activates before meteor damage is dealt. Meteor Strike has cooldown of 12 seconds and Nova 16 seconds (both have -20% cdr glyphs).

It's recommended to use Talents (EP) points on Lightning Strike Propulsion that reduces Nova cooldown each time when Lightning Strike crits. You can also use talent points on Nova Velocity which speeds casting Nova up to 15%.

In PvP Nova can knockdown opponent. Generally knockdown is weak effect since opponent can escape with Retaliate. Also that should never be done on stunned opponent. Nova is also too slow casting skill to use on that purpose.
