I decided that i was going to defeat all the bad guys before going to the pirate island ive defeated the main bosses the dragons the slave lords the twisted rune, and all of the liches except kangaxx, ive defeated his first form but not his second as he imprisons me too damn quick, are there any ways of getting around this, can you find freedom scrolls before cutting the deal with bodhi or the thieves,are there any tips you have which arent cheating or cheesy cause im stumped at the moment, he even imprisoned the almighty pit fiend any advice will be helpful- thanks

Ways to counter his Imprisonment,

Spell Immunity( Abjuration),
Berserker's Rage,
Minsc's Rage,
Protection from Magic scroll,
Protection from Undead scroll( only for his Demi-Lich form, do not use when he is a Lich),
Spell Trap,
Shield of the Archons.
