go near the first little lake you encounter in Oslya... in the upper side... you will encounter a green veloc. (in the battle are 2 dinos, 1 red/fire and 1 yellow/heart) and a blue pterodactyl... you take 100exp more or less... but not alone... if you going afk and be alone, you probably lost exp and nothing more...

for now, the 2x exp are suspended... i hope the GM reintroduce it with the new server and ver.3.0 launch...
