As this was the first time anyone in the campaign took any damage, (the type was irrelevant), I brought up the idea of possibly modifying how natural healing would work in the current game.
I am glad it worked out for you - but such stuff really should normally be discusssed before character generation, as it can make a big difference in how folks choose to put together their characters.
I wasn't singling out any specific player/character for not wearing armor, taking damage from a piercing weapon or because the attacker intended to kill them.
But those were all things you said in in the post, seemingly trying to support/justify your choice. So, was all that text meaningless?
