Arise

 is an active skill that can be taught to Priests at level 24. It cannot be ranked up at later levels.

can be performed with a staff by the Priest to stand up a party member who has been knocked down and then buff them to have higher balance (ie. resistance to knockdown) for the next 5 seconds. The stand up effect does not apply to the caster, but the increase in balance does, so this skill does have a place even when the Priest is soloing. However, because all classes have the Retaliate skill anyways, this skill isn't too useful in PvE. It is more useful in PvP, when party members are repeatedly getting knocked down while their Retaliate skill is still on cooldown.

Rank table
To obtain, one must find a Magic Instructor and pay a certain price of gold.

Glyphs
To glyph, a glyph must be obtained and learned only once. At level 60, a character has 50 glyph points available to spend on all available priest glyphs. Most glyphs, specifically common glyphs can be purchased from a Glyph Master, while fine glyphs must be looted from enemies.
