I’m not sure about this, but something about landmines seems to be not working correctly. Either torso damage from mines is calculated wrong or torso damage might be displayed wrong. On a full HP tough character, wearing all reinforced bone armor pieces and the O-yoroi on top of the bone suit, I was killed in one turn from a land mine. I think I could have been very unlucky, but the action log didn’t seem to record the fatal land mine damage that finally destroyed my torso.
Edit: Nevermind, issue already reported on github. I think that all non-player creatures only take torso damage from land mines. When the player is hit from a land mine triggered by someone else, the player is treated as a non-player.
