For the beginners/Noobs i advise you head to the Auto-Chipper once you have gained at least to level 6 7 8 if you dont know your level go to party and it will be on the bottom, Save beat it save close game relaunch rinse repeat if the boss didnt show it then you did it wrong
Be Very Careful when doing this You dont want to become to strong now do you?
You will gain amount of 500 xp if i can remember do it a couple times as you want
i did it 4 times
witch in total is: 2,500 Xp
With most bosses that are strong will give you 2,000 xp or 1,500 So make good use of there xp Gain.

If in Dusting fields do the same with the snow man and gain a total of 1,000 xp
I did it 3 times witch in total is 3,000 xp.

Now keep this in mind This Does not work with eyesore.
Also The bosses will punish you for doing this grinding
There damage will increase like crazy so make sure you have a healer or a endo with defence.

But! Atleast make sure your not ontop where the boss will appear Or this will not work EVER Again.
"Make use of this grinding way until scott probs nerfs it"

On to The expert way!.

For this part i advise you to grind Using Browboy He gives a total 1250 xp everytime he dies
On hard mode if i can remember its 2500 xp

as i have said if you want to try it on the security boss go ahead but keep it in mind

Save Beat the boss Save Close the game Relaunch and he will respawn
so in hard mode you can keep getting that 10000 xp X3

I hope this helps you in leveling up to beat the scott cawthon boss

Have fun!!!
