Holy Word: Chastise is a level 24 Holy priestHoly Word ability. It is an instant-cast damage spell that disorients its target.
Tips and tactics
The disorientation effect of Holy Word: Chastise can be invaluable for priests in PvP, and the spell's damage, though not considerable, can be useful as an extra nuke. However it should be noted that the disorientation effect will break immediately upon any damage taken by the target, meaning that this effect is best used for crowd control or to allow time for healing, escape or the use of an ability with a long cast time. However even in hectic battleground encounters, it can still be used to interrupt a caster at a critical moment.
