You guys are seriously ignoring MH lore. Ceadeus are deep sea underwater creatures and live in deep caverns, so you can't fight it like Jhen. Abbysal Lagiacrus also live in deep waters and cave and rarely come to the surface. The only way to fight Abbysal would be in some new underwater cave area where he could go on a surface and fight.
