Fly wings, and other things of a bunch.

[GM-Garr]

Yes, that's exactly the reason for this poll.

Current situation: if you're casting a skill, you can use Blue potion, but can't use fly wing or anodyne.

Possible outcome: if you're casting a skill and use Blue potion, nothing interesting happens, you continue to cast and potion has its effect applied. If, however, you use fly wing or anodyne, the skill you're casting will be interrupted, and the item skill will take precedence, so you'll teleport/endure.
