Friendly Mecha knights need to be fixed in three ways:
1. Make them use their shields.
2. Make them shock less.
3. Increase their damage/health.
Friendly mecha knights are amazing and helpful, in the royal jelly palace, one almost survived the arena before the boss, and another almost survived the boss battle, but they aren't doing enough damage, and they get killed too easily.
Another idea: Make them a rarity.
