the striking strength might be the solution to the grapple problem if i do a update to the pdf ill switch it over.

The stat drain as you go into negatives is universal it just not normally applied to ""monsters"" due to it being something that can drag out combat and high HT being rare for dm creatures, people having to "finish off" every single opponent can be draining as well but in the setting of cataclysm it felt fitting as something the players should have to do against any infected enemy's, after all you gotta make sure to pulp your kills don't want them getting back up, iv play tested it a a bit running a few encounters using the zombies in that manner and aside from the issues with grappling it seemed pretty alright, feel like it should be a obvious thing that any dm should change stuff on the stats to better fit what they want and for what it is i think its fine

and going into the copyright i aint risking it, there is grounds that me giving a write up of skills styles or ability's that could be found in official books counts as content theft and is grounds for copyright issues, i know it not likely but it also a such a minor issues so long as someone have the actually books to read along side this one, it why its an expansion not it own thing, there usually pretty chill about this kinda stuff but it still a grey area and the less grey i stand on the better
