I've played a couple playthroughs now and I have literally never come across shovel. After I learned that the coffins are trapped, I just never interact with them unless I'm in the mood for more combat.
Well, as Lotus Noctus says the coffin that has Shovel’s scroll isn’t trapped, so you can grab it without a fight … if you know which one to go for
.
But I didn’t come across Shovel either until I saw it talked about by other players, not because I didn’t have the scroll but because I’m a terrible hoarder of scrolls and consumables. I guess I should have realised there was something different as the scroll is described, I think, as “Summon Quasit” rather than “Summon Familiar”. But I do hope Larian will signpost the fact that this scroll has location-specific content more clearly in the full release, perhaps with a cutscene when you pick up the scroll.
