Grimoire curse/corruption - Continuous corruption buildup

Not sure if this is intentional or not. I just did a mission where I carried a grim. Throughout the mission I kept building up corruption even though I wasn’t getting hit by melee, hound, poxburster. Wondering if anyone else has noticed this or had this occur to them.

Yes, this is intentional. Picking up the grim will cause everyone on the team to suffer one Wound’s worth of Corruption.

Yes. What I’m saying is that my health would continue to tick down by 2 points every so often. Even though I wasn’t taking hits that would cause corruption.

And you just carried that piece of heresy for 20 quid and nothing else, thank you for your service
