Is it possible to reach the top level?

[Vilk]

That's not so simple because the xp given by a fight is dependent of the player level (and most probably that's not dependent of the stack relative size so it's probably useless to attempt fight with reduced stacks to get more xp).

From various players attempt quote in this forum it seems that it's impossible to reach level 31 without to exploiting a random bug.

But that's the point, level 30 is the max, the game mechanism allows higher level but that's pure mechanical, the game mechanics probably also allow level 100... and then use monster regen just to reach level 100? Tedious and pointless.
