Just thought I'd note that while this may be correct eventually, at present my Nanaly has 542 attack base and when used with Spica and Uzume buffs just barely is unable to kill the eyes. She does however seem to deal more damage than my Zola with 610 base attack, suggesting that while Awakened archers do likely have a buff to attack vs. flying enemies, it is not as large as they would get on DMM Aigis yet.

My Spica however with 505 attack is more than able to 1 shot the eyes when her skill is active (at max skill level).
