Notes
This spell does not have a somatic component, so it can be cast while wearing full armor and shield, ignoring arcane spell failure.
Since this spell is not be removed by invisibility purge, it makes for a great combination when used with invisibility purge to remove the concealment granted by improved invisibility on an opponent while retaining concealment on oneself.
The concealment granted to the Warchanter by this spell will be lost if the Warchanter equips anything in their offhand. When casting this spell, Warchanters gain an extra 5% conceal if their offhand is empty, and lose 5% if it is not.
