1) You need to take out the brothers so they don't appear. Do the two side dungeons first.
2) Take out the minion so you only have to face one foe.
3) Use your own minion to distract.
4) Build up your blades and traps. hit big.
5) Take in friends if you can.
Wait a minute!? y'mean if you do the two side dungeons first, the brothers dont appear!? I already beat Jotun but I never knew that! Noone told me that! and all this time i was wondering what those dungeons were for...
I think there is a problem with taking out the brothers on the left & right. I did that twice & they all still appeared for me. Have no advised about getting help. I seem to always missed who is on my friends list.
