Well there's no hard rules.. (except the hard rules*
)
But Nevo and Maddawg are basically the creators of the map, so they get to play a benevolent dictator and grab some more perks.
Level 2 and 3 are often given to active developers of the map
You could ask Nevo if you want one.. it's got a significant effect on early gameplay tho, so its not sth that gets given away easily, especially higher tier mills.
In addition to that some items are unique, only 1 person has it, those are impossible to aquire for others. this includes for instance some event rewards.
Some items are not unique, but were only available for a limited time.. (such as silverring and slujj hat) those are not covered by the "hard" rule (silverring was in the starter pack i think?) im sure its possible to get slujj also but im not familiar with current terms. ( being a dev helps tho, so heres another reason to join the team!
)
*hard rules: you must demonstrate at least some skill... if you want to go round this, you need to buy Nevo a luxury yacht or sth
