As someone who's first event was Jack Frost, this is gonna be one hell of a week. Yata and fire weapon are must get, then not sure if i should prioritize Ixion or the Thunder weapon. Really don't plan on ever playing thunder, but with gacha, you never know. Ixion would mostly be 5 copies for the eidolon shop. The 163 halfelexirs i currently have should get me reasonably far though.
