So this one is a bit of a doozy.
By the end of the game, you should be level 30 naturally (31 if lucky). So that means you'll have to earn two levels worth of experience points and getting from level 31 to 32 costs 108502 experience. I'd scrape a couple thousand off of that number for 30 to 31, so that's a lot.
So this guide is going to require you to have 3 thing.
- A save before the point of no return (quest: Glory Forsaken) or anytime after level 30.
- Max level on Blood Vortex or Blood Toll (Vortex is prefered)
- The Harvester (found with Elaine's Treasure Map in Juma)
- (Optional) Hunter's Mail, as it's good against Staff type weapons
You're going to want to go to the Necropolis in the Juma Tribal Area (in Africa). You'll want to talk to Gero who can be found wandering around in the Necropolis or in the building immediately to the left of the entrance. (The entrance to that building faces the Necropolis.)
Talking to Gero will allow you to fight in a tournament of five waves.
The first three waves are two people each.
The fourth wave has four people.
The last wave has five.
I've been getting 16 experience for each wave, with the exception of the fourth which gives me 28 experience. Using the Harvester to fight gives you additional experience when you kill the enemy. So twice the amount of experience is gained each battle when I use it.
So usually I get around 228 experience per fight.
Now, you can stay and fight until you reach 32 or leave when you're 50%/75% through and you should be able to gain enough experience to level up before you finish the game.
Fighting the Juma Warriors can be tedious and annoying. The Warriors will surround you and they will attack you multiple times. They will trap you and you won't be able to move. So you have to be super careful and roll/run away when they look like they're about to attack.
In the last two waves you can use your Passage skill to 'die' and move away so they aren't aggro. Then move to one of the sides and lure them to you.
If you're getting too low in health, run far enough away and cast Blood Vortex/Toll on them.
You can fight in the Necropolis as often and as many times as you like, there are no limits.
