How often does the damage annulment proc?-Gregrowe 16:56, 10 September 2008 (UTC)
Just from experience
This may be a bit late but I guess its better later than never.
I have had my mantle for about 4 years so I have had some experience using it. I don't have a percentage generator but it seems that it will usually nullify 1/20 physical attacks (including TP moves)
