The loot that drops from Lek does not warrant the amount of time to kill this sea monster. Please add better sea crystals, Crow Coins, ship upgrade mats etc.

i never tried to kill that creature since i dont do sea content but i love the sea content people and will give u a like

Sometimes I running out of cannonballs before one ever spawns. I got three green crystals once off normal sea monsters so the boss itself doesn't serve a very big purpose.
