Grym died in 2 rounds to two level 4 batttlemaster fighters. He was blinded by the sorc, then both battlemaster fighters dumped menacing attack's on him with action surge, an an offhand attack with another mace.

"Was that it?" may have been spoken.

The lava elemental is also super underwhelming.. a chromatic orb can deal 40+ damage to it it you twin it. We took it down to like 7 hp round 1, killed it round 2 even after it got its 35 hp heal.

I don't think Grym should be weak to bludgeoning at all... and he shouldn't be resistant to so much stuff.. like even force damage? really?

But if monsters do have weaknesses, I don't think the right click examine should jsut tell youthem.. pathfinder gives you some information based on your arcana/nature/religion etc checks and I think that makes more sense. But just telling people what somethings weakness is doesn't make it a puzzle. Gryms fight would be a lot less anticlimatic if we didn't know right away that he was weak to bludgeoning.. if we had to experiment a bit to figure it out there would be 1 or 2 rounds of us freaking outthinking nothign was going to work before we finally got the relief of finding outtherewas a way.. but by that time we'd already suffered damage and be on edge.. that would be an interesting fight then.

"Just don't examine then" or "but players can always look it up on a wiki/guide".. It's different when it's part of the game itself.. like you're always able to look up puzzle solutions online, but games don't let you "right click -> solve" puzzles still, that would be ridiculous.
