Oriana Theorycrafting.

Lets get it started. I really adore this champion.

So far i got
9 red magic pen
9 mana regen seals
9 magic resist per lvl glyphs
3 magic pen quints


She desperetly needs mana regen. Rush a quick catalyst or perhaps a tear of the godess.

I say tear of the goddess and then build it into archangel's staff. Catalyst is a little less useful since they nerfed it to regen health and mana over time instead of immediately.

Good point since the nerf catalyst doesnt hold the same lane sustainability it once had. Games have yet to last long enough so far.
But people as of release day seem terrified of her and are stacking magic resist. So.....I have done AAstaf into a void staff and seems to work well. Also CDR boots seem awesome for the attacks u can spam your Q just be weary of your mana. An Early blue from your jungler is HELPFUL and lane dominance.

Just build her with wards and run around the map its gg then :P
