Here are some basics about the PvP server, and what you can/ can't do based on the plugins I have installed.
What you CAN do:(subject to change)
>>>Claim land for your Castle by placing a Bedrock block.--Radius ~20
--Enemies can't build/ break blocks
--Enemies can't interact with Doors, Trapdoors, levers, and Stone Buttons
--TNT and fire spread are ON
--Cannot overlap with Village Zones
--Cannot be taken over by another player (they can be raided and sacked though)
>>>Claim a Village by placing a Coal block.--Radius ~30
--Enemies can't build/ break blocks
--Enemies can't interact with Doors, Trapdoors, levers, and Stone Buttons
--TNT and fire spread are ON
--Cannot overlap with Castle Zones
--Inventories are protected (as long as you own the area)
--Villagers and Animals are protected
--CAN be taken over by another player
--Will generate resources
>>>Use TNT, Lava, and Fire Spread--TNT will blow up anything except for Stone Brick (Stairs, Mossy, and Cracked), Stone Slabs, Diamond Blocks, Beacons, Obsidian, Chests, Ender Chests, and Bedrock
--Iron Fences require 4 explosions to break
--Iron Doors require 2
--Some rules apply (anti grief/troll rules mainly)
>>>Utilize ANY vanilla Minecraft item/object as of MC v1.6.4--Hoppers, Portals, TNT Minecarts, Horses, Maps, etc
--Only exception is the placing or breaking of Diamond Blocks (you may still craft them if you wish)
>>>Earn money by selling Emeralds--Each Emerald is sold for $25
--To sell, use "/sell 388 <amount you wish to sell>
>>>Create NPC "Sentry"s or "Ranger"s--Use the command "/npc create <Sentry or Ranger> --trait sentry" to create a soldier
--Costs $100, or 4 emeralds
--Can equip them with various weapons and armor
--Can create paths/ waypoints for them to patrol or return to after fighting
--NPC's (with sentry trait) will auto attack anyone/anything (besides the owner) within sight that is within ~15 blocks
--NPC's have 20 HP (same as players) and regen 1 HP every minute.
--Can be lead into battle by the owner (using the bodyguard function)
--Can distinguish allies from enemies and not attack them
>>>Teleport back to your bed--Use the "/home" command
--Must remain still for 8 seconds, or else it will reset
>>>Use Movecraft Sea Vessels (not yet implemented)
--Completely free, except for the resources of course.
What you CAN'T do:(subject to change)
>>>Break Diamond Blocks or Bedrock--I will configure your Castle Beacon for you
>>>Build/ break on other people's land--If they have claimed it, you can't break it (except for the Coal block, you can break that).
>>>Break the Rules--You technically can, but if you do I won't be nice about your punishment. I am trusting you guys with a lot. Lets be nice (to a degree
).
