There is no rebuttal, these are true and tested facts.  No reply needed, however there will be a few that do dispute this and this is fine and to be expected.  But the facts don't lie.  Drum roll please.......

This was a 2 month study done on ALL demigods, factoring in many things along the way...starting armor value, skills, speed, ect..ect..

We'll start with the weakiest and work down the list to most powerful:

8.)  Regulus.  Although his snipe and mine skill are nice it just doesn't do enough damage.  Regulus skills are only useful in a game with someone you know or if you end up with a good teammate.  These skills are only good for finishing the opponent off after your teammate has widdled your opponents life down to nothing.  Regulus with speed buffs is fair but he lacks in serious hit points starting off and holding flags at the beginning is difficult for this character.

7.)  Torchbearer.  Nice skills as he can go either Ice or Fire but again, this character lacks true power when holding flags or going face-to-face with a more powerful opponent.  Speed is average, hit points average upon starting of game.  Again, this character is more or less a finishing off type of character as his skills aren't enough to do it alone.  One pro, this character levels up quickly.

6.)  Rook:  Extremely versatile, lots of hit points and armor.  Very powerful at holding flags at the first of the game.  Does serious damage to structures....however, he has one weakness, he's extremely slow at first and even with speed buffs if choosen is at best average against other demigods as his light towers help but only in the beginning and mid-game.  Rook is good for one thing and one thing only in my opinion and thats purging ahead slowly doing as much damage as he can to structures.  He is a great supporting character in a multiplayer game, however he has to be careful not to go to far inland or he will get caught up by the opponent and enviatably killed as he retreats. 

5.)  Sedna:  Quick, nimble, great skills, just doesn't have the umpf needed though to take on most of the demigods in a balls out fight.  Her minons are weak compared to other demigod minons.

4.)  Oak:  Awesome fighter, great skills that actually help during a face-to-face battle.  Strong hitpoints and armor, his minons are average at best and the raise dead skill is nice...Oak is most powerful later in the game level 10 and higher he becomes quite a powerful adversary.

3.)  Unclean Beast:  This was difficult as I had to spend extra time studying this character.  He's pretty much balanced but where he excels above the rest mentioned thus far is his ability to strike hard and fast.  For a good player, if he can master the UB the UB is unstoppable.  His speed is above average with all speed buffs applied.  Does great damage to enemy very quickly, able to stun to finish opponent off.

2.)  Queen of Thorns:  Looks can be deceiving, but I tell you she is undoubtly (in the right hands) completely unstoppable.  She is most unstoppable because of her bramble shield effect and her minons and her ability to move in out of battle quickly.  With the right build, QoT is extremely hard to beat and she does great damage.  Her ability to regenerate mana is by far one of the best in the game.

Now for the Best....

1.)  By far, hands down, the Vampire Lord is absolutely the best character in the entire game.  He has ungodly skills that pretty much decimate any foe he comes upon.  He's ability to have a total of 15 POWERFUL minons at his disposal will crush anything. Able to carry battles on at multiple locations at once.  Able to quicly drain hit points and his bite goes through armor like a knife through warm butter.  He is absolutely over-powered in my eyes, moves extremely FAST in and out of battle. At level 10 and above he is a tank and basically unstoppable....period.  Until he is nerfed, my advice is this...if you see that your opponent is playing Erebus just concede because your doing nothing but wasting your time and his by staying and playing.  He mows through all the other DG's like they nothing.  I spent the most time studying this character because I was fascinated by actually how powerful he was.  I'm curious if the developer's realized this?  He is by far with no rebuttal THE BEST DG in the game.

    Some will disagree, others will not...it doesn't matter actually...this is my 2 month study take it for what it's worth as the numbers do not lie....
