This was a Continued Plugin by @emericask8ur called "WarningSign"

Version 3.x.x
Have you ever wanted to protect an area and nothing does the trick? Well here is your solution! Placing a sign down and writing "[Caution]" on the top line will cause anyone within a customized block radius to be kill by a customizable event!

Features
1) Allows for custom strike radius.
2) Permissions Support.
3) Ops have full permission.
4) Not case sensitive.
5) Will not target mobs.
6) Customizable striking options

Lightning (Strikes player with lightning)
Explode (Kill player with an explosion)
Ignite (Lights player on fire)
Volley (Fires arrows apon the player)
Golem (Spawns a hostile iron golem on the player)
Wolves (Spawns hostile wolves on the player)
LavaTrap (Encases the player in a bedrock/lava trap)
WaterTrap (Encases the player in a bedrock/water trap)
SkyDive (Teleports the player way up into the sky and drops them to the ground)
Random (Picks a random strike to attack with)

Instructions
1) Write "[Caution]" on line one of the sign.
2) Enter a number that will be the strike radius on line two of the sign.
3) Type the type of strike you wish to use on this sign. (refer to features for list)

If done properly, the players name will appear on the last line of the sign and the player will receive a message of confirmation.
