I am more weirded out that the new draconians trend towards boring. Baaz is the most prominent for me, turning to stone and trapping the weapons that killed them was scary and weird, requiring players to rethink equipment. I remember the DOS computer games and just getting in the habit of carrying two primary weapons for every character because of the dang things. The petrifying gas, Is both more frustrating and less interesting.
I think Bozak used to do fire damage on their boom, I think they came out the best of the new ones.
The mind**** of Shivak being lost is a shame, I think the 3rd edition one had a will save to avoid a short term stun due to mental trauma of watching yourself die.
Kapak is fine, the puddle not being a persistent terrain effect was a loss though.
Aurak I think is actually the same as it was or at least close, I think the energy ray was a fire attack, and I think the death throes lasted longer and could chase people (I might have done fire damage too).
