This post is not for discussion, but for announcement purposes only. It is regarding the use of Animal Empathy to tame hostile animals, bring them into to a town and then release them from domination. It is a potential form of Player Killing (PKing) that requires DM supervision (similar to laying traps in high traffic areas of town).
It is not a question of RPing your ranger or druids using animals in an agressive manner against towns and/or townfolk. It is a question of bypassing the town's IC defenses in an OOC manner (since the town guard would not allow a potentially dangerous animal past the gates).
It is also a question of risk balancing. It is already considered PKing to bring someone into an area that will obviously kill them (leading a low level player onto the Bugbear screen would be an example), but bringing over-powered opponents (say a dire boar, as an example) into town in this manner has the same end result and is also considered a form of PK and will be treted that way by anyone using this manuever.
If you have any questions on this posting, PM a Player Lead (like Kallenthen or Yith) and they will answer your question and clear any updates to this posting that may be required.
