How to unlock the Raksha Research Master achievement in Indivisible - Definitive Guide
Doing this will not prevent you from getting the 0 point
This achievement is like the platinum trophy for the Playstation. It doesn't matter if your save file never has both level 5 attack and defense at the same time, you'll still unlock that at the end once you have every other achievment.
For the Defense Level 5 upgrade you need 20 Ringsels.
You will be introduced to them quite early in the game by two characters who also help you to rise attack and defense.
There are 108 Ringsels in the game and you need 50 to upgrade attack or defense to level 5.
So unless you want to collect 100 it would be a good idea to not go over level 3 for both collect 35 Ringsels and then max one attribute reload your game and then max the other.
After being introduced to th characters you will find them in your inner world (Hold B and press Up).
The guy helps you raise defense and the women can raise your attack if you have the respective amount of Ringsels.
They switch locations as your inner world grows progressing the game but are normally easy to find as it is quite small.
They will also often mention when saving that you collected enough to raise an attribute.
That said, there is a way to cheese this trophy. Once you collect enough, you can save the game, put them into attack or defense, quit without saving, reload the save, then put them into the opposite one. Doing this will net you both level 5 trophies, this one for defense and the one for attack (see Shakti Research Master), as well as the level 3 and 4 trophies for both. Once you do that, you can reload once again and divide them however you please.
See my Collectibles Supplemental Guide for a text- (and some video-) walkthrough on how to get these Ringsels and more.
NOTE: I do suggest using the first few rather than saving them, but only the first 10. Put 5 into attack (you have to anyway as part of the story), and then 5 into defense. Once you've done that, stop using them and save them until you've amassed 45, at which point you can then do the save-reload method. This is because the monsters in the game can hit quite hard and, if your stats do not increase as theirs do, the difficulty level will quickly become extremely challenging. Why 45? To reach level 5 in defense requires a total of 50 Ringsels, and level 5 in attack also requires 50. So, assuming you've already put the 5 in each that I mentioned, 45 will be enough to get you both trophies.
You will find red stones called "Ringsels" as you travel through the game's levels. There are 108 to find, and they are generally hidden in hard to reach places. A large majority of them won't be available to collect the first time you go through an area, due to the metroidvania aspect of the game. Once you unlock new powers, returning to old areas will yield new sections to reach.
To reach Level 5 in defense, you will need a total of 45 Ringsels. I would highly suggest putting 5 into attack and 10 into defense right away, then saving a total of 35 before doing anything further. Use that opportunity to max out your defense for this achievement, then reload your save and start working on attack. The game's combat is very easy and having more attack is much more beneficial.
