One of Rook's greatest strengths is that he's so big that he covers up much of the battle area. Get some smaller demigods hiding behind him, and your opponents might not see what's happening until it's too late. I've been killed by way too many Rook/Regulus comboes, simply because I couldn't tell whether it was 1 on 1 or 2 on 1 until it was too late.

It's not hard for an Erebus to get his health per second up over 100.  Somewhere in the 120-150 range even.  That can be rough to fight.

To use a stunlock kill, your opponent needs to be dumb enough to stay when a stun + attack combo would kill him. Batswarm is nearly uninterruptable and lets him get away from anything. He's squishy, though, so he has to batport out a lot unless played or geared better than his opponenets, in which case he usually ends up with pretty high health from bite + poison blood.

I play Erebus all the time (check out my Erebus guide) and beyond that shameless plug I would like to say that a level 1 rook has ZERO chance at beating a level one Erebus with Monks.  Quite simply Erebus has too much Hp and regen with the monks and bite to even be in any sort of trouble.  Beyond level one no sane person is going to let themselves get hit by hammer slam.  If rook winds up Mass Charm will stop it.  If you get boulder rolled you can mist or bat swarm.  Erebus is not that great of a 1v1 deathmatch Demigod unless he has an item advantage, but he is quite simply the hardest Demigod to kill in this game.  He has a debuff wiper as well as invulnerability to wait in Mist.  And a teleport in Bat Swarm.  A Strategic Erebus is both devastating offensively and terribly hard to kill.

P.S.

I have played with this guy...maybe he is referring to me that would be cool

You can't mist or swarm out of stun. Just saying, about the boulder roll comment. It works for rank 1 but once he has rank 2 or 3 you can't dodge it anymore. Just because I wasn't sure if you were chosing not to make that distinction or if you simply played against terrible rooks.

Other then that i completely agree with you. Erebus doesn't have skills that are innately devistating the way other DGs do. bite is great, but thats it. He doesn't really have the auto-attack or spammable spell damage to make him a crazy assassin without being overgeared. He's really just great at getting away or assisting. Don't get me wrong he CAN hold his own. But I generally feel I dont get kills unless they overextend themselves.

Well, but consider that the only part of that 120 healing per second coming from himself explicitly is 20 HPs from poisoned blood. All the rest is just what anyone can get. Sedna is the one who really tanks out the self here, giving a potential 89 HPS (If I remember the aura/boost bonus' correctly). Erebus just gets 20 hps.

I really think that Erebus' strength comes from his flexibility. Mist, Bats, and Bite all make up a triumvirate of very effective solutions to various strategies and situations. Bite + bats = good at catching runners. Bats + Mist = ability to GTFO when needed. In my opinion, level 2 Batswarm is the most effective ability in the game. With mana, it allows you to both gank, run, and chase almost any opponent.

Now, I don't currently think Erebus is too strong, I'm just pointing these things out.

It's rediculous to try to explain why 1 DG beats another DG 1v1. Some DGs just beat other DGs 1v1.. it's why this is a team game. I usually play QoT or regulus, and regulus can't beat anyone 1v1 (of equal gear and skill). But 2v2 and kiting, he's amazing. QoT can beat just about anyone 1v1 by spamming shield.. but has no escapes for 2v1. Each class has strength and weaknesses. It's important to mention that most people play conquest and the goal is to kill the citadel, not get as many kills as possible. That being said.. mist is a pretty awful AOE..same with bat swarm.. so erebus lacks the ability to really push creeps. Yeah he can bring his own army in and there's that inifinite mist thing.. but if he goes infinite mist he's really too weak to take another DG 1v1.. and if you have 1 DG on your team with good aoe you'll rofl his creep waves push to their citadel much faster than batswarm and mist will.

Bat Swarm is an amazing creep AOE...until there are giants it kills everything.

Yeah, you probably shouldn't use Bat swarm against creeps except very rarely. It has a long cool down, and not having it ready when you need it causes much frustration on your team.  It's like the Regulus who can't snipe the guy about to run, because he decided to melee-snipe someone in his lane...
