1) 1392 - 1395
2) No idea since I no longer play. Avatars originally only supported 1 or 2 stats so go figure. Do what you think is best.
3) In earlier versions skills can reach till around 150 (hacked) but now I am not sure. The most obvious giveaway will be to have
overpowered status windows which is why its recommended to unequip all hacked EQ before you save and close the game.
My 2 cents
No need in my case my attack/def is untouched lol. Reason why I even asked is because I don't need a lot of things so spreading it around is just pointless. Cooldown reduction, hp/sp absorb a bit of evade and I'm pretty much happy already.
Fyi... just because game doesn't display attributes doesn't mean they dont work
It seems to fully support 7 attributes. My problem is game gets laggy and im not sure if my phone just dying on me... since it used to play z5 just fine. Or it overheats or its causes by weird gear stats.
