Karambwan

Karambwan is fish that can be fished at Karamja with 65 fishing after partially completing Tai Bwo Wannai Trio.

How to obtain
You must first fish Karambwanji with small fishing net. Then use Karambwanji on Vessel, and with Vessel with bait, you can try fish Karambwan. It is recommended to have many Karambwanjis with you at once since Karambwan tends to take multiple baits before getting caught.

Cooking and other
If you attempt to cook Karambwan without doing Tai Bwo Wannai Trio to end, it will become automatically Poison Karambwan. When eaten, it will deal some poison damage(though you won't need antipoison since it only hits once). By using Pestle and Mortar on it, you get Karambwan Paste. This is strongest weapon poison in game and can only be used on spears.

After doing Tai Bwo Wannai Trio, player can cook successfully Karambwan. However there is no certain level where they stop burning, so player can burn them even at level 99 cooking.

When successfully cooked, they heal 18hp when consumed. Also interesting thing with these is that eating them will not interrupt combat, so player could effectively heal and keep fighting. This is very useful trick to have when PKing.
