Upon arriving on the island, the boatman at the dock warned you to be cautious and directed you to the healer in the outpost.
'Best to make whatever business you have here quick, my friend. There are terrors lurking around this island that turn the innards of men to jelly - just by sight. Talk with the healer if you want to know more.'
Speak with the healer at the stalls within the outpost of Bel Inzûl.
