i think of a new item called:
(the) Knockback-landmine
and item that when used is barely to no visable to other players.
only you can see where the trap is.
it will activate if a player gets into the 3x3 area of the trap.
this trap will if activatet knock everyone from it away.
the knockback strength is like the knockback-boom-box.
if you run into the trap it wont activate but if other run into it, it will activate.
the trap does not do knockback on the user of it.
the item can only be found in chests with an 1/15 chance and can be droped from the lucky ore with an 1/100 chance
