I was in a silly mood while thinking about spells, and this came out:
Beer Strength
Type: Enchantment, Poison
Cost: 2, 0
Target: Living Creature
Trait: Dissipate 2
Target gains a boost of courage, but is somewhat disoriented. Target can ignore guards, but one guard in zone can counterstrike if desired regardless of this creature's melee target. Target gets Melee -X, where X is the number of dissipate markers on the enchantment, and gains the Pest and Unavoidable traits.
If we ever get a Drunken Monk type mage... this could be more amusing.
