Spoilers below....

Im having trouble with the demon dimension fights, the tenari and the other demon guy. I understand you only need one heart but both seem difficult and I tried to look up a guide on how to beat eother of them but iy boils down yo "buff your party fighter and let him tank while you kill them"...uh first of all I dont have a foghter, I have Minsc as my tank and Valygar as Dps, Yoshimo for stuff, Nalia, my Wizard and Viconia as support.

I tried casting all my buff spells on either Minsc or Valygar and sent summons to help them but even with my entire party focusing on the main demon he still deals 3 times more damage and for some reason heal as soon as he is close to dying.

Im tired of this quest, the halflings were fun to kill but the Tolgeryas fight was super annoying as well and only won due to lucky Breach sticking to him.

I wanna beat this quest already so please tell me the easiest fastest way to get that heart so I can move on with my life.
