Only half of everything. Still vulnerable to Time Stop, Disease, Web, Slow, Vorpal effect, Slay, Power word Kill, Disintegrate, Petrification, Blindness, Silence, Deafness, Intelligence drain (Mindflayers), Polymorph, Poison, Pause target.

You also get a -2 penalty to AC, thac0 and damage for 5 rounds when it ends... Thac0 is an issue to the Berserker/Mage 13/28, not to the Kensai/Mage. Meanwhile by the time these characters unlock their warrior levels, 2.75M XP, their boosted saving throws are already so good that they can tank Beholder rays and Illithids without immunities.

I'd say both builds are very close, with Berserker 13 being slightly more defensive and the Kensai 13 slightly more aggressive. Since spells and equipment already make the ultimate defense, I tend to prefer Kensai because it's quicker to deal with enemies due to a better accuracy and initiative. However, it must be easier to get a Berserker up to 2.75M XP thanks to armors, helms and bracers.
