The driller goes after anything just like barbs and archers.

it unlocks a special ability at lvl 3 in ur labrotory the ability is drill, it allows you
to go under ground undetected by everything but hidden traps such as
bombs giant bombs and spring traps. You could go under ground for 3
seconds at lvl 3. At lvl 4 you can go under for 6 seconds and lvl 5 10 seconds
it looks like its name driller but holding a huge drilling its hand and kind of fat.
It costs 320 de and goes up by 25 each lvl. It's max lvl would be lvl 5

Few things. What do you mean by special ability? Is it like the heroes abilites or just like how witches spawn skeletons? The amount of time the troop is underground is WAY TOO OP. Also leave the numbers part of it to Supercell
