Guthatrice egg

A Guthatrice egg is a special egg used in summoning. To obtain a guthatrice egg you must get a green bird's egg from a bird's nest and use the spirit cobra's special ability, which is Ophidian Incubation on the egg. Summoning a spirit cobra requires 63 summoning. At 43 summoning, a Guthatrice egg can be used as an ingredient in a Spirit Guthatrice pouch. To make a Spirit Guthatrice pouch, take the egg, a pouch, a green charm, and 88 spirit shards to an obelisk.
