Fairy

From Nostale Wiki

Fairies are a sort of "buffing pet", meaning they behave a bit like pets, but do not fight for you. Instead, they empower your elemental attacks. There are Fairies of the 4 different basic elements: Water, Fire, Darkness and Light. Each Fairy amplifies your damage and gives you its elemental attribute. The attack bonus is based on the Fairy's mood, which goes up more the longer you keep it in combat. It will initially give only a 20% boost, but will eventually rise up to double damage (100% extra damage). The Fairy needs to eat too though, so remember to always keep some food with you (snacks or dishes won't do!). The cheapest option is the Bacon and Egg Fry that costs only 120g at the Mart. The Fairy needs to eat every half an hour, and if it can't have food, it will start feeling bad again (hunger makes you grumpy, common sense). The first Fairy you acquire will be the Fire Fairy, which you can get from the lvl25 Act 1-2 Hero Mission as a Bonus reward. The list will be updated along with discoveries of other Fairies.
