About cygnus noble mind skill level

Ok, so like the thread title says,
Do you need to fight the KoC arkarium to level up the noble mind skill?
Or would it be automatically be leveled at certain levels?
(This is post Cygnus revamp btw)

After revamp it raises by 1 every 5 levels after 120, and is maxed at 150, iirc.

So is there any need to fight the KoC Arkarium before the revamp?

If you don't plan on getting the new Cygnus Knights to 150 I'd do it before the revamp.

My mihile has lvl 6 noble mind, will he retain it after the revamp?
