I just wonder how smooth or immersion breaking "Cheat Death, Fire, Light, Death, Shadow, Gravenail, Boltab 6 to the chest from a 2 handed sword calling blunt through Andy" is
You misunderstand, when I say "no flavour" I mean the call is simply what damage you would have taken. If the person casting Cheat Death would have taken 1 water damage, the call is "Cheat Death, 1 damage, Andy". If it was 5 rift damage the call would be "Cheat Death, 5 damage, Andy". It's as per the current wording and you're passing on the injury, not the cause of it.
The other way is that the person takes a Fire Strike (or whatever) and shouts "Cheat Death, Fire Strike, Andy" and you take a Fire Strike. If you're immune to fire you ignore it, if you have DRs to fire you use them or you can dodge it or whatever.
