ReiInformation and Guide

Here's the explanation for all the numbers and colors used in the guide:

• 10/5/7 means upgrading Skill 1 to lvl 10, Skill 2 to lvl 5, and Burst Skill to lvl 7,
• Yellow means the immediate investment when u get the unit. There are 3 reasons for this:
• If the unit is Meta or High Priority, it will have a starting investment of more than 1/1/1 (such as 4/4/4) depending on what the unit provides.
• If the unit is Medium or Low Priority, 1/1/1 will be mentioned, meaning no immediate investment is required, and you can invest in this character if you need to use it according to the priority listed.
• If we deem that a unit does not have usable skills to be meta for any gamemode, no investment will be mentioned.
• Blue means minimum investment to take advantage of the Nikke's skills. There are 2 reasons for this:
• Sometimes, minimum investments are breakpoints such as for Noir or SAnis.
• Sometimes, minimum investments are just the ideal way to progress to upgrade that unit, before moving on to Recommended and High.
• Red means recommended investment for F2P players,
• Purple means maximum recommended investment, in order to get the best out of the unit. You should only try to reach these investments if you have a surplus of Skill Books leftover.

More info:

• The skill investment list below features a lot of Level 4 and 7 because they are easier to understand. Any higher levels will cost a new type of resource.
• However, you may choose to upgrade to Level 5 if you need a stronger effect instead of 4, as the increase in Blue Manual cost from Level 4 to 5 is still low. The leap only starts from Level 6 onward.
• There is also a leap from Level 3 to 4, so if you want to save a tiny bit of Blue Manuals, then leave at 3 instead of 4.

This Overload (OL) Recommendations and Priority guide unravels in detail everything you need about a character in terms of priority, overload targets (effects), and order of acquisition, alongside some notes to explain our thinking process.

For OL targets and order of acquisition, we decided to divide the target effects into several categories.

• Essential: With all gear combined, your unit must have the roll(s) prescribed as a minimum requirement. Example: Charge Speed on Alice. You cannot compromise on these rolls.
• Ideal: These rolls will improve your unit's performance significantly. Aim for 2 lines of Essential/Ideal per gear for maximum performance and the best Return on Investment (ROI). If you get 3, you are lucky. You can choose to only have 1 as well to save materials. Example: Elemental Damage on Scarlet.
• Passable: Low-priority line that has either limited value or the impact is not as strong as other rolls. Should this show up as a bonus together with a better line, you can choose to keep them. Example: Charge Speed on Red Hood.

Overload effects are ordered by importance from Left to Right, which means anything on the left provides more value than the right. Effects that belong to the same group generate too similar an impact to make a difference (and are sometimes interchangeable). Try to follow this order as faithfully as possible for maximum mileage.

Additional tips:

• Priority (PvE/PvP) isn't necessarily lower than Priority (Universal), which has no tag/label. It just indicates that this unit performs only in select types of content.
• If a suggested effect has the number ×2 next to it, that means you should get the effect on at least 2 gear. The same idea applies to other numbers.
• Focus on obtaining Essential(s) then you can start worrying about optimizing your rolls. Units require these to function, and the impact is too massive to ignore.
• If a unit has no Essential(s), that means their performance is not that dependent on OL, but they can still benefit from good effects.
• Remember that this is just a recommendation list, and attaining perfection is impossible. You will have to make some compromise, pick whichever rolls you desire the most, and conserve as much material as possible.
