Fly wings, and other things of a bunch.

[GM-Garr]

As far as I know, it doesn't block normal consumables that, per se, heal, add stats or so on. This does affect, however, consumables that cast skills (fly wings, anodyne, scrolls and so on). I'm just not sure how the game will react to casting a skill while casting a skill (Yo dawg!), so the safest way would be to "cast cancel" the one in casting. But this will affect all people, hence the poll.
