Efficiency Theory |
| Defeat M10 Robot on Hyper difficulty without dealing any damage to it outside combat. |
Efficiency Theory is a Steam achievement in 100% Orange Juice!.
Requirement
Win a Co-op game against on Hyper difficulty without dealing out-of-battle damage to it.
Notes
- Boss's cards that deals out-of-battle damage to itself (such as
Self Destruction) isn't included. Player's cards, however, will nullify the achievement.
Strategy
- You would want to have at least 2 Attackers because
Protect will reduce its battle damage, and it is very important to wear down the stacks by attacking multiple times, and Attackers will attack first. It is possible to beat it with only 1 Attacker, but you would require to endure more turns. - There must be at least 1 Support to ensure that your teammates wouldn't die instantly by the Boss's card because of low HP. Healing cards such as
Dinner cannot be used when the Boss uses 
EMP, which renders players to be unable to use their cards. Supports should try to stay alive as much they can because when a character would revive with 0 REC, it would require 0 stars to revive, and having full HP makes much more safer when the Boss would use out-of-battle damage card. - Guardian is optional and its unique skills would help other characters especially Support to not to get KO'd easily
- Helpful cards such as
Extend, Dinner, 
Saki's Cookie, 
Dinner, 
Pudding, 
Portable Pudding, and 
Metallic Monocoque are useful to make the characters stay alive. 
Dash! is a very powerful card and easy to use since it can be used both running away from Boss and reviving the character.
Serene Hush is very useful and cost-effective compared to 
Tactical Retreat and 
Shield Counter when the Boss would use a card that heavily favors the Boss (
Scrambled Delta Field and 
Imaginary Numbers). Players should consider putting some of this card for safety.- is another viable choice (usually as Support) for this achievement. His stats fare pretty well against the Boss and his Hyper can be very helpful in breaking down the shield or dealing great damage once Scrambled takes place.
