I started my second playthrough, with a bard. (What was I thinking )

It looks like they strengthened Zalkh on the nautiloid. ( I started the first PT with a ranger , beginning of August and managed to take Zalkh out. ) The number of misses from our friend the mindflayer now were impressive. But the reason why I add this in the "problems" topic, is that my bard succeeded in downing Zalkh twice with Tasha's uncontrollable laughter.
And twice the stupid mindflayer skipped his round and just stood there, instead of whacking the prone devil.

Tried several things, but never got Zhalk under 50 HP before the party, including the stupid mindflayer had gone down.

There also seems to be less loot on the nautiloid compared to august.
