The generally agreed-upon strategy at the moment seems to be to place Grievous Injury deathtraps in central locations and hope that Richardo hits them as often as possible (in particular, he’s quite capable of hitting them multiple times in a run, and probably will due to the random-walk nature of the Crypt). This is normally done with “unless he is Agile” features, because the stronger version hardly does anything (and is almost always inferior to separate Grievous Injury and Light Wound features).

This buffs the stronger version, and nerfs the weaker version, in order to a) make the standard strategy weaker and b) make one of the alternatives a bit stronger; Richardo now can’t be affected by more than one “standard” deathtrap per run, but you can have a harder-to-stop version if you’re prepared to pay for it.

This also fixes the rules for Grievous Injuries in a similar way to my CFJ for Light Wounds (although unlike with Light Wounds, the previous version wasn’t technically broken, just a time bomb that might catch out future proposals that introduce new methods of Grievous Injury, so it doesn’t need a CFJ to fix).
