Durkon was pretty confident that Malack *couldn't* hurt him, just immobilize him. And didn't stop thinking that until Malack demonstrated he could dispel the Dwarf's protection against his vampiric abilities.

Malack also does not attempt to crush anyone in his final moments, even when he was desperate to at least do a take-you-with-me and what was left of the Linear Guild would have been easier to grapple than Durkon was during their fight.

I don't see any conclusive evidence that the training Malack mentions having includes Crushing Weight of the Mountain.
