Is this badge actually possible to earn?

I've looked into this badge; it's what's known as a "custom badge". What that means is that (as far as I can tell) it's manually awarded. (Another example of custom badges are the computer programming contest badges.) Every custom badge that I'm aware of is manually awarded, which makes me think that Herculean can't be obtained (unless a staff member decides to give you the badge).

I've got 10 000+ proficient skills and still didn't get it, apparently max LVL now is around 170, which is equals to 14 000~ skills, so I have 4 000 more to do, and maybe I won't get it anyway

you will bro, you got artemis and maelstrom, you cant get herculean if you try (at least I think so)

00cool thank you, I'm kinda demotivated recently, but I'll try uping levels anyway, by now I'll try reaching LVL 150 and 10 000 Mastered skills, even tho they don't give any badge
