Luckily, this particular weapon has both a double and triple border for me to explain.

The double border indicates that that particular skill can evolve once. (edit: nvm only skill extraction will level down a skill) -What does this mean? You can evolve the same skill on different weapons as long as requirements are met-
The triple border is similar but instead of being capable of evolving once, it can evolve twice but still follows similar rules to the double border.
Skill level needs to be maxed for the multi-border to take effect and allow the skill to "evolve" to the next rank.
Raising Momo's partner level will bump the evolution limit and allow you to do higher level evolutions such as rank 2->3 and 3->4, etc.
Best part is? This is one of the few features that doesn't cost any ryou! -looks at the poor drained wallet of mine and looks at all the people I know who've dumped millions of ryou into them weapons- (warning:timetolevelskillsnotincludedthankyoufortakingyourtimeandwehopetoseeyouagain)

-Level skills
-skill level applies to all weapons and are independent with skill rank
-evolution requires double border skills and max skill level to do (limited by weapon)
