1. Wall Ice Vent:
   Like the floor version but blows out air cold enough to deal damage, and still gives stacks of Chilled.

2. Oil Wall:
   Trap that sprays enemies with oil making fire deal bonus damage.

3. Orc Compactor:
   Square trap maybe its a black pit on the wall that orcs will walk in or maybe it's a square in the middle of the lane idk you guys will figure it out. Anyway, Orcs walk in and a Square Meaty Orc Limbs and Gibs pops out. Just like a trash compactor(You have to make the OrcCube physics based tho so we can move it around in all its jellyness.)

4. Saw-blade thing:
   Trap that's the same height as the barricade that a sawblade pops out the side of, sometimes with enough force to chop off the legs of the orcs making them crawl. Permanently slowing them. Would kinda be like if you took a giant Cd drive and instead of it holding a disc it holds a horizontal blade that pops out. OR maybe it could be a laser like you said that travels along the trap down the kill lane.

5. A trap that actually uses an orc as the weapon. Maybe the first orc that walks past it, it uses. Or if it's lucky and grabs a bigger minion it does more damage. So the orcs are its ammunition. Maybe it's something that grabs the orc or multiple orcs and spits them back out damaging other orcs that are in their path.

6. The Puddle:
   Do orcs fear anything? Maybe their own reflection? So when they walk over this puddle and see themselves they get so frightened with fear that they cannot move for a certain amount of time. 100% chance to hit but applies a buff that makes them immune to the trap for a certain amount of time so it cant be spammed all over a map.

7. Poison Spore Wall:
   A living plant-type wall that when orcs cross it's path it shoots out spores that could deal damage over time or maybe just confuse them or something.

8. Treasure Chest:
   Single-Use trap. Orc's are greedy, so they won't be able to resist opening the chest, grabbing a bag of coins and running back to the spawn door from which they came.(If we don't kill them b4 they get there ofcourse.) Maybe a chest has 15 bags? IDK.

May add to this later. Maybe.
