To get to Prince Aka you will see on your map while where Aka's door is that there are other Kroks, go to the first Krok and he is a Rank 3 boss kill the one in the next room after him and basically use your map, if you have quest finder on it will only point to Aka's door but you cannot get in until you've defeated the other Kroks in the other rooms.
I think you guys are confused.karanahn palace is like the vault of ice.you have to fight three other bosses to get to your target boss.also the map dosent show you the other three bosses that you have to fight to get to prince aka karanahn.the door that goes to aka only opens when you defant aka.so dont go left go right then go right again(sorry if I spelled that wrong)to meet the first boss you have to fight to get to aka.the three other bosses are at the right of the rooms with the sarcofegos(sorry if I spelled that wrong)and do it until you get to aka.
I'm having a heck of a time as well. Are the the princes in the hallways of the Barracks or in rooms? I have fought Kiwu (a mander), lair of taskmaster, & Alchemist Kepi, but I don't think these are the three princes.
What are the princes' names? I think I've done this quest about 5 times, & it's sucking the joy out of playing. I'm not a fan of "dungeon" quests at all!
