Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

The ooze in soubar's well appears to be completely immune to physical damage, but is not immune to critical hits (it still shrugs off physical damage even on crticial hits).

That doesn't make any sense. I critically hit this thing for 66 damage, and it shrugged it off.

Ghaunadaur strong.

I managed to kill it with pommel strike.

I could not hurt it with fists or using slashing damage.

Fists worked well for me. (Str18)
Slashing weapons never worked on oozes (here and in the sewers + gravecave)

Will be fixed with the Spawn Overhaul. Good pickup.
