Yes, I am aware of the significance of the number 666 in christian mythology. Supposedly it is the number that signifies their deity's antithesis, so it is considered evil.
1 xp to level is still worse than 666 to skill point though.
Hmmm 666 well its a hebrew thing that each letter has a value as per number and meaning. God 7, devil 6, and christ 5 as the devil did come first and still is important. So each tetter having a number and being ruled over by a spirit and on mirror side a deamon the numbers add rank.
Devil copped three strikes before being booted so 3xhimself being naughty = evil
From her on in it gets complex and rather occult so we will leave it with the basics.
On a different side and the meaning of life 42 = 6x7 or god forbid 7x6 brining both god and devil back as one balanced thing ie the tree of life.
Now that you asked the question and got a reply does it mean anything :)
