Why it works here
Her buffs grow with her Energy and are given to the whole party, so each of her points works for five players. At level 220 she adds 130 damage to every hit of every party member; at level 400, 270. On our server her buffs also last longer the more Energy she has.
History
The Energy Elf or buffer: the most wanted party member of Seasons 1 and 2.
