Griffin Pet

The Griffin Pet is a Pet obtainable from the NPC Diana. The pet is not required to spawn Mythological Creatures, but it scales their difficulty with its Rarity. The Griffin Pet is considered a good early to mid game Damage dealing pet due to its high damage stats and the Legendary Constitution perk that gives the player high level potion effects.

How to Obtain
The Griffin Pet can be obtained by buying it from Diana when she is elected for Mayor for or purchasing it from the Auction House. When you purchase it from Diana, it will always be.

The Griffin Pet can only be upgraded using Griffin Upgrade Stones. The stone upgrades the Griffin to the same rarity as the stone, however, the Griffin can only upgrade one rarity at a time.

How to Upgrade
Since Kat cannot upgrade the Griffin Pet, it must instead be upgraded with Griffin Upgrade Stones.

To upgrade the pet, obtain the Griffin Upgrade Stone that is one tier above your pet's current rarity. You cannot skip ahead. For example, if you have a Griffin Pet, it can only upgraded with an  Griffin Upgrade Stone and not a  Griffin Upgrade Stone. It should be noted that a Base Griffin Upgrade Stone is required to craft all rarities of Griffin Upgrade Stones.

Once you obtain the upgrade stone, summon your Griffin and right-click while holding the upgrade stone, the same way you would give it a Pet Item or Pet Food.
