99% of the time, sustained damage looks a lot worse then it really is. As long as you have a good frame, and your electronics tucked away, preferably shockmounted, the odds of your robot being damaged beyond repair are minimal.

I should know, thanks to Kan-opener and THz ive been in that situation twice, and my total damages never amounted to more then 50 pounds worth of steel and aluminium. And my robots where a mess after the fights. But nothing a little elbowgrease cant handle.
