Amphibious units? Who needs TFT lol

This is very easy to do and very quick, just make a trigger that switches collision off for whatever unit in this case a scaled up Infernal and it can go anywhere, including up cliffs so you may want other triggers to stop it doing that lol.
EDIT: BTW this IS a ground unit not a flying unit or hovering or any of that stuff.

Yar, this is true.

The only reason for amphibiousness is to make it easier for map makers to make stuff water/land but not cliff/tree/terrain passing.

You can also do movement type "none" and they can transverse across anything.

I assumed movement none would make them stay still :bgrun:

only setting its unit move speed to 0 still stop its movement
