Party Bonus. This is where the party's at.
- Concise description
Party Bonus. Ain't no time like party time.
- This bonus is gained by using a Party Beacon.
- This effect increases the duration of visual effects for fireworks (e.g. Sparklers).
- This effect will also cause your character to glow slightly, similar to when enchanted with Divine Fire. A higher[verification requested] Party Animal title lowers the chance of getting the glowing effect.
