Ibis

The Ibis is a summoning familiar which requires 56 Summoning to use. Although the Ibis does not aid in combat, it assists a player with an invisible Fishing boost of 3 levels.

While the player is fishing, the Ibis will forage tuna and swordfish. The Ibis produces fish when the player fishes at any fishing spot. Each time the ibis catches a swordfish you gain 10 experience. Each time the ibis catches a tuna you gain no experience, the amount of experience obtained from an ibis caught swordfish is not influenced by swordfish gloves or the Sacred clay harpoon.

A Barb-tail Harpoon does not work in creating this familiar

Fish rain
Fish rain is the special move of the Ibis. The special move makes fish (Only Shrimp, Bass, cod, and mackerel) fall out of the sky. Fish Rain can be activated by having a fish rain scroll in players inventory.
