Solo Hunt
To achieve level 80 fast, it’s recommended to hunt only
Champion monsters, which is Fierce Battle Infernal Lava and Fierce Battle Boogie Bolt.
Party Hunt
Since RF Online update 4.151, bonus experience obtained when making a party increased. The best spot to fast gain experince is still hunt
Champion monsters, not
Elite monsters. If you take a look on this table, you can notice the big difference of HP monster between
and
.
The
Champion monsters also weaker than
Elite monsters, so instead of hunting a difficult one to gain slight better EXP, better to hunt large quantities of
Champion monsters.
