[City of Thebes] CaltropTrap_BP

<hr>#### CaltropsOne of the four types of basic traps in City of Thebes, caltrops deal a set amount of damage per second to players who run over them, not including the player who laid them down.

Laying caltrops over one another creates a higher-damage version (stacking only once), and caltrops laid over a mine will destroy the mine and spawn caltrops that also apply scrap bleed.
