Satan's Folly on the Wiki says it has an errata with the wording Praeceps listed, but the
errata listing has nothing listed. Anyone have a link to that as an actual errata?
As originally worded, this should be an instead ability, not a Heal. In fact, Heal doesn't really work at all, but Instead defines it perfectly.
Until I actually see where the errata was issued, I can't say to use that. If there were an errata, I imagine it was before we better defined "instead" and would propose moving back to the original wording with a play-as for "instead"...erm...instead
