New trap that's very similiar to the big bomb starting at th7. Place the caltrops to slow down your enemys starting at lvl 1 at Th7: at -2 to movement speed for 2 seconds it's area of effect would be 3 tiles
Lvl 2-3 at th8: lvl2 Caltrops at -3 to to movement speed for 3 seconds at 3.5 tiles
lvl3 Caltrops at -4 to to movement speed for 4 seconds at 3.5 tiles
Lvl 4 at th10: Caltrops at -5 to to movement speed for 5 seconds at 4.0 tiles
You get 1 additional set every town hall level starting at 7 to a maximum of 4.
This may be a very OP trap but I think it's a cool idea. Maybe something similar could be implemented.
