Spiker

A spiker is a player whose goal is to quickly inflict massive amounts of damage to a single target, with the hopes that they can kill the enemy before he has a chance to heal, or be healed. This is opposed to a Nuker, whose objective is to attack multiple enemies over a longer amount of time.

Spikers are usually Elementalists using Air Magic, but some Necromancer builds can work as well.

Spikers usually work best with PvP, as most players are smart enough to get out of a nuker's AoE spells, but can't really dodge lightning. They work well in PvE, but using fire to damage numerous enemies at a time is better as the monsters will usually stand in one place and attack instead of moving around.

Spikers seem to be becoming more of a hot PvP trend lately, and the amount of them is severely rivaling, if not beating, the Nuker. There's really no easy way to avoid lightning spells, so the best way to take them down is to take advantage of the fact that their armor is weak and send focus your strong attacks on him.
