Rates and PvP

Experience

Experience is staged, so the early levels fly past and the high ones stay worth something:

Level 1 - 8 : 20x
Level 9 - 20 : 100x
Level 21 - 39 : 80x
Level 40 - 59 : 60x
Level 60 - 79 : 30x
Level 80 - 99 : 20x
Level 100 - 150 : 10x
Level 151 and above : 5x

Killing players gives no experience at all.

The other rates

Skills 10x - Magic level 5x - Loot 8x - Spawn normal speed.

Skills and magic level also train while you are offline, at 1.5x. Log out in a safe place and you keep making slow progress.

PvP

The world is open PvP. You can be attacked from level 1 up - there is no protection level to hide behind, so learn the map before you wander.

Dying costs 10 percent of your experience and skills. An unjustified kill gives you a white skull for 15 minutes.

Bonuses on top

Two creatures are boosted every day - see Boosted Creatures - and the rates above are multiplied by those bonuses when you hunt them.
