Control

 is one of the Evoker Specialization Classes in Devilian. Render your opponents immobile. Push them into the path of an oncoming storm. With coordination and timing, this skill tree allows you to reshape entire battlefields.

Tactics
In the right hands a Control specialized Evoker is very, very dangerous, both to single targets and to groups. Her primary at-cost instant skill, Lightning Blast, not only initially calculates at a whopping 180% of skill damage - one of the highest values per shot known for zero-cooldown skills - she can fire it in any direction while at a full unmounted run including behind her, even while in the middle of an unmounted Autorun without breaking the Autorun. This gives her completely unequaled kiting ability, and that high damage-per-shot aspect of Lightning Blast combined with its very respectable area of effect can also let her very frequently get Multikill bonuses. On top of this several of her abilities when combined in the right sequence can cause horrific damage to groups of non-boss enemies (bosses being immune to status effects); she can use Black Hole to pull a bunch of enemies into a small area, then Frost Field them to freeze them in place, then hammer that spot with combinations of Icicle Storm, Lightning Blast and Meteor Strike for absolutely ruinous damage. If you can, try to use the RPG control mode where you move with the WASD keys and fire spells with the mouse and number keys as this will definitely give you the best combination of mobility and damage output.

A Control-based Evoker is so lethal that it is almost debatable if the Devilian form is worth using, except perhaps against bosses since the Devilian mode of the Evoker does have better single-target damage output.
