Caller
The Caller, or VoR is a role in all common DoASC tactics. It is always done by a mesmer with VoR, but otherwise the build can vary, depending on the tactics.
Contents
Role
Traditionally, the Caller is an experienced spiker, literally calling the spikes by pinging VoR on a central target for the other spikers to follow. In a more experienced team, the Caller is not expected to guide the other spikers, but because of the high damage potential of VoR, this role is fairly responsible, and some knowledge and ability are required.
In some tactics, but not all, the Caller brings Edge of Extinction.
Build
The core spiking skills of the caller build are VoR, Unnatural and Shatter. Being a mesmer, you always want to bring Mistrust, and "You Move Like a Dwarf!" is now core skill on caller across all tactics.
Optional 1
The first optional is always a 4th spiking skill: it can be Wandering Eye (FBGM Tactics), Overload (Golt Tactics), Cry of Pain (French Tactics or DoA 3-3)
Optional 2
The second optional is either Edge of Extinction in Golt Tactics and DoA 3-3 or a shadow step, EE in FBGM Tactics and Return in French Tactics
Attributes
Callers typically run 12+1+3 domination, 8+3 fast casting and 10 in their secondary attribute: either Beast Mastery if you bring Edge of Extinction or Illusion Magic (with another superior rune) if you bring Wandering EyE. If you have Return and no use for a secondary attribute feel free to boost Fast Casting to 12 and put 3 points in Shadow Arts
