The Magic Arena!
In the arena, the only combat style you are aloud to use is magic. The way to get there is mini-games teleport, located here on the spellbook.

Then click the Magic Arena at the bottom of the chatbox.
When you get there, there is 4 things you can kill; Black Demons, and Forgotten Mage's, they look like this:
The Black demon is level 172

The Forgotten Mage is level 44

The point shop is ran the rewards guardian at the spawn, if you talk to him he should open up a shop like this, that sells Full bloodmage gear, Stark wings and Staff's of Sanguine.

There are two types of safespots for killing these people.
The first safespot is hiding behind the teleports. There are 4 teleports around the arena that you can safespot on.
You need to stand here

This safespot works on every monster in the arena, at all 4 teleports on both sides!
The second safespot is on the southwest side corner of the steps, this safespot only works on the demon that is closest to you on the steps, so dont try it on all corners!

When your killing the monsters, they give you points to spend at the rewards guardian.
You get 25 points for killing the monster, and then they drop an item called 'Pentamid' These give you 10 extra points if you talk to the rewards guardian and give them to him.

So thats 35 points every kill! Both monsters give the same amount of points, so its up to you what one you choose to kill!
Props to Genja for help on the second safespot!
Goodluck guys<3
