I have an idea for a new item; the warp stone.
It is a stone that allows for fast TTR with a cooldown of one second.
It works like this; 1 warp stone with emu of 3 would teleport you 6 squares( im reaonabky sure ttr is already upto 6 square radius) with a variable of 2 squares iny any direction (so effectively 4-8 squares forward) but as you cannot control it if you use a stone and it lands you in an inhabited square (one you cant naturally walk on) it will teleport you to NCA.
Im not sure if it should be a craft or an eng item.
This item I think would be very handy if used correctly but if you spam them without thinking it could get you killed.
