@FTGM, Ice akin to Glass!?! Wat!?! Despite what that thought is, Azir was able to easily escape Ice which Silver used to freeze in a AoE.

How ever, that was my whole Point of saying Fire and Sand don't mix. It is because Natsu can turn Sand into Glass with Fire and Heat. I am actually discussing this with someone else that if Azir's ability is anything like Juvia's magic where they can turn their bodies to their respective elements, then Natsu is a major weakness for Azir since he can solidify his body.
