Topic. Some Grimoires in various points cannot be picked up.
And why can’t we drop a Grimoire?
Grimoire is supposed to be a highly risky secondary task like in vermintide. If a player picks it up, they have committed to protecting it for the whole mission and your team needs to do anything it can to keep the holder alive.
Grims and scripture spawn locations do need to get fixed tho, some are impossible to pick up.
