A lion belch is a skill that requires years of eating garlic rings at the tavern. The hero has to eat these garlic rings and produce gas via beer... Being as heros drink beer so often, it's not hard to obtain.
The skill while in action releases a massive wave of doubled bad smells, and creates fear in your opponents eyes
1-5: opponent will gag
5-10: opponent will back away a minimum of (250 meters)
10-20: opponent will jump off a barely survivable cliff to escape
20+: opponent will drown themselves in the shower, then if revived drown themselves in the bath, then if revived flee to space because some god is out to get them and make them stink forever...
