NIKKE skill recommendations
When it comes to investing in NIKKE, the breakpoints are usually pretty simple: level 4 for non-priority skills, 7 for good units and skils that increase damage / buffs and level 10 for meta units that benefit the most from the extra levels.
But not always you can just follow that pattern, since some units require specific levels for their skills to work. Hence this page, always updated skill recommendations for all the units in NIKKE.
Characters that have either 1/1/1 or 4/4/4 are units not worth investing unless they are your waifus.
