Arcane Aura

Arcane Aura is the fifth skill in 's Reticence skill branch. It reduces the she gains by 30% when she has any  active.

Overview
Melia's main aura is Elemental Burst, which doubles her damage output, so any reduction in aggro for it is a big help to the tanks. also applies, though it's not quite as big a deal. As a link, it's probably a bit too expensive because most other party members don't synergize well with it - Shulk's only aura goes away when he uses an art (it does help for auto-attacks), Reyn and Dunban don't want to reduce aggro (and Dunban has anyway), Riki doesn't need help not getting aggro, and Seven can't link it regardless. This basically leaves Sharla's Drive Boost (since Covert Stance does the same thing but better), where it isn't that bad actually, but even then there are more important star skills for Sharla to link from Melia.
