The Repeller branches off smasher at lvl 45. It looks like the smasher, except that its body is octagonal. Instead of ramming into enemies, you can use a shockwave (like a expanding circle with the color of a team DM base) to damage things close to you. Everything in the bubble will get body damage. also, Bullet stats return when upgrading to this tank: bullet speed will turn into bubble size, bullet penetration will turn into bubble protection (reduces damage taken), bullet damage into bubble damage, and reload into bubble health.
