Trap Limit Per Skill Type
Each player can have a maximum of 12 active units per skill type on the map at any time. Placing a 13th removes the oldest one (first in, first out). Each skill type counts independently.
Example: A Hunter can have 12 Ankle Snares, 12 Blast Mines, and 12 Land Mines active simultaneously — placing a 13th Ankle Snare removes the oldest Ankle Snare but does not affect the Blast Mine count.
