Huzuni is the best client for starters. They currently aren't accepting staff, unless you're good enough and you get picked.
If you want a good client buy Iridium. If not code your own. The staff has their eyes peeled for players that are worthy enough to be a staff.
Resilience is a good pvp hacked client. I advise looking for one with these aspects: A good fly hack A reasonable kill aura Anti knock back and criticals You can get hacked clients at wizardhax.com which redirects you to the genuine site once clicked.
Hacks I use: Huzini is one of the best you can get actually... Right now i'm done with hacks. But here's my list's of hacked clients I have. Kronos Huzini Resilience The best hacked client is Iridium, You can fly, and it has the BEST PvP modes! It does cost money though! So I'd start off with huzini to see if you "really really" like it! How to get staff: You can get staff by helping people, and being respectful to people. But please do remember, that if you ask for it your chances will go down, and you'll probally not get it. Goodluck on staff!
Huzuni is almost just as good as Iridium. It's just the hype about Iridium that makes it supposedly the best.
The staff are looking for people that would make good helpers. Don't ask to be Helper because it will decrease your chances of becoming one.
