Whether you are here because of Invisibility/IvU, Headshot, Decapitate, Assasinate, Pickpocket, etc. These are issues stemming from the Body Types change. The single Body Type per mob change is here to stay, here's the best, I think, people can accomplish if they want to 'fix' issues with this change. 1.Understand the issue you're having completely before proposing a solution. 2.Establish WHY there are a subset of one body type that have special characteristics, which enable a specific mechanic, and WHY that should not have been removed from game play. 3.Propose a new Body Type that addresses the mechanic you're looking for. Preferably 'break-out' an existing Body Type into the relevant subsets. 4.Keep in mind this is a vast task separating out mobs to be assigned to the correct subset. Here's an example: I think this should address Invisibility IvU and Headshot on undead target issues, by breaking out Undead into two categories. Undead Corporeal: Has a physical 'body', can be Headshot, can not see invis (because they use barely functional physical 'eyes' to see), is affected by Undead spells. Undead Non-Corporeal: Has no 'physical body', can not be Headshot, can see invis (by sensing the 'life force', not 'seeing' with eyes), is affected by Undead spells. Feel free to discuss or laugh all you like.
