PallyPower 4.0 is a scaled down version of PallyPower. This add-on provides an interactive and easy to use interface that allows you set your own blessings (Righteous Fury, Aura, Seal and Blessing) and automatically check for missing buffs.
Buff button controls are:
Left click = cast RF
Shift+Mouse scroll = RF on/off
Right click = cast Seal
Mouse Scroll = change Seal
Left click = cast 60 minute blessing
Mouse scroll = change blessing
Shift + Right Mouse drag over any of the buttons = move PallyPower Frame around
In combat none of the spells can be changed due to the in-combat lock-out. To access PallyPower interface settings use the standard Blizzard interface menu / Addons tab. To change PallyPower keybinds use the standard Blizzard keybind menu.
