Could I be able to beat all Legendary(Ring of Blood) at lv 75 as a mage using Holy tier1 and Wind tier1(for Konata) ?
I think you can when you at lv 80, with 2nd infusion slots.
The real points are:
5AP on slow, weakness, bewilder (must)
5AP on haste and shadow veil(optional)
enough prof for regen/haste/shadow veil
enough infusion of Elec/Dark/Cold for spirit attack (check this page:
http://ehwiki.org/wiki/HentaiVerse_Bestiary)or enough scrolls of life for spirit attack
BC Raiper+BC Shield is still useful for Yuki. parry + block can prevent about 30% of her damages.
