Overlord

Is it in the order you learn them though, or is it based on the level/rarity/strength of each skill? For example it makes more sense that he started copying people after his defeat to Gazef, after all nailclipper comes from stealing one of Gazef's moves.

I'm pretty sure it's in order you learn them based on how that's how it is ordered for everyone else and especially since that is how it is ordered for characters from Yggdrasil so it's basically confirmed that's how it's ordered.
Also as for when he copied Gazef, he actually did so before the series started but never used any of Gazef's skills because he wanted to win with his own. He initially only copied Gazef to gain a better understanding of his moves for the next time they fight but started integrating Gazef's skills into his moveset after meeting Sebas.

There is also the fact that as a bandit he likely copied any useful skills from anyone around him, it could be a fellow bandit or knights guarding a shipment or transport etc.

It's also interesting that he doesn't have the mercenary job like Gazef does despite having worked as a mercenary as well.

If he was so focused on learning everything around him not to use it but to understand it and combat it with his own style. I could see why it would be considered genius and not give him the merc levels.

But then how is it determined what jobs you get in the NW? It seems like level doesn't matter since there are low level characters with jobs that usually require a high level but are the prerequisite jobs required too? I wonder about this since his jobs seem to have a jump in power (or at least it seems that way based on the names) in that he goes from Genius Fighter to Sword Master to Sword Saint. Then again he might be a special case thanks to his Genius Fighter allowing him to copy other fighter classes.

Also if Genius Fighter can copy skills regardless of job (as long as it is a melee job) and level (since he could copy skills from Gazef who was a higher level) then does that mean that if he had survived his duel with Cocytus that he might be able to learn some of his skills too?
That'd be pretty interesting to see and is a shame we probably won't get to find out since Mare breaks his ice cube.

It'd be nice to get a book that explained how the job system worked in better detail and maybe a list of all the jobs like how we got an explanation for types of spells tacked onto the end of one of the bonus books.

He fights Cocytus? I never even knew, you damn guys and your reddit spoilers.

Sorry, user. In the end he gets frozen and Cocytus plans to add him to his collection but Mare (supposedly according to some anons) accidentally pushes on and breaks the ice block containing Brain which kills him [/ spoiler]

I like how each guardian has important works to do. Especially Shalltear seems pretty important right now. Makes me happy they all get make full use of their abilities. But it seems like Nazarick is is desperate need of manpower.
Just trying to keep the current territories stable already require all hands on deck. Imagine the future where there is still hundreds of nations to take over. Maybe is better to just wipe half of the world population to minimize the troubles

Nope. Is was a fake spoiler. Cocytus manage to preserve it as his collection.
Is a dumb spoiler anyway. We are taling about Mare here. You really think he could actually trip? Him? The most capable person in Nazarick is Mare. He might act meek and shy, but hiding behind that facade is something else entirely. Mare is the most scariest of them all.
