Basic Attack
"Just seeing that Stand is making me feel older than I already am. That's the ability of Grateful Dead, so be careful using it around people you wanna keep around. Right now, Grateful Dead can only punch things. Not exactly unusual. Just keep going." © Jotaro, the Marine Biologist Your barrage inflicts the Old debuff. Duration and damage depends on temperature (the biome you are in).

Alternative Attack: Grab
"Now, Grateful Dead can grab a target and forcefully age them. The amount of time aged depends on how long you hold them. Don't do handshakes." © Jotaro, the Marine Biologist Grateful Dead grabs someone and deals massive damage over time to them. Unlocks at Tier 2

Special Ability: Gas Spread
"So, this Stand just became even more of a safety hazard to any allies, because now it can spread the aging effect as a mist. It's not as immediate, but now multiple people can be aged forwards at once." © Jotaro, the Marine Biologist Grateful Dead starts spreading aging gas, affecting players and enemies. When an NPC enters its range they get the Old debuff (damage depends on tier and temperature of biome).

Unlocks at Tier 3
