I'm stuck and I may have to resort to an earlier save.

I'm trying to get the ammo for the special gun in Okasankaar. I've got 3 of the booyat from the lava cave, but can't find any more, and I need another 2.

I've read I'm supposed to get one from the prisoner on the soldiers island, but I've already been there wiped the place out and returned, but I can't seem to find a way back, as none of the boatmen will offer to take me.

You must blow in the horn, and he will come back (but only, if all soldiers were dead). The fourth booyat can be purchased from the dealer Zafar.

Thanks, I reverted to an earlier save and got all the booyat.
