[2021] Cinderswallow Urn was stealth nerfed, removing the Movement Speed on Flask Effect :/

This is a bug with an upcoming fix. Flasks that don't have the movement speed modifier will be able to get the modifier via Divine Orbs once it has been fixed.

EDIT: To clarify, the flask will need to have the "50% Chance to avoid being Stunned during Flask Effect" if a Divine Orb is to roll the movement speed modifier onto it.
