I got few questions related to PvP:
1. If my character throws a caltrops, sets a trap, uses persistent spell that targets area, etc, do I need to set people to hostile? Assuming that I do intend to use it against someone but without ability to chose who will be the victim what should I do? Leave player list intact, set hostile to person I would like to be the target, set hostile to anyone getting close, set hostile to anyone on server? Now, if my character is far away from such place and is unable to check who's getting into, is there anything that can be done? What if it's an NPC, that gets hit without my knowledge? Also, do people affected know what and who has hit them, if the character is far away from place?
2. If my character wants to use spell or trinket, lets say silence for example, for RP purposes - to make other PC stop talking for a while, then how such action should be taken, as on outright PvP and attack, similar to casting fireball on other? Is there any rule or guideline? Is it up to players to decide?
