Daisy is an Amethyst Spider. In canon she spends most of her time as a lifelike statuette the size of a real tarantula - that is, she can fit in Griffin’s palm. When she is summoned, she becomes a Giant Spider and grows to approximately the size of a bull mastiff. Once summoned she lasts for 12 hours or until she’s reduced to 0HP, whereupon she reverts to her statuette form. She can’t be summoned again until 24 hours have passed. In the campaign she’s basically an eight-legged dog - she adores Griffin and wants to be everybody’s friend.

Additionally, unlike Griffin, Daisy has an Intelligence modifier. It's only +1, but it's still pretty significant. Her Wisdom mod is 0, though, so between the two of them, they have one entire INT and one entire WIS.

In Avalon I expect the statuette thing will be nixed and she’s just going to be a full-time Giant Spider. As a thought, though, it would be fun to find a way to restore that versatility in game.
