Ok, this was a fun fight, lots damage but no party deaths
Some questions:
1 Plants have low-light vision, but cant be blinded -im sure i saw that mentioned in threads elsewhere-that mean they shoulnt be affected by the smokey 'pyrotechnics' spell version, it got hit by when cast at the flaming sphere it was in, or can things still be concealed against it?
2. As it was Huge, and therefore bigger than the grease spell cast at it, was it immune (as it also cant be tripped)
3. Had it failed against the pyrotechnics, would the -4 str penalty been cumulative with the -3 it had from its (saved) against ray of enfeeblement [if it had failed against both spells would it have been at -11 strength!!!]?
Spell caster heavy party with bear companion, acting as a damage soaker!!
