Two Minutes with the Archdemon Stunner

It turns out that an Atlanticore with skill at level 1 has a cooldown of 5 seconds.  Thus, when amped up to max speed via Pumpkin Power, he can synchronize exactly with the stunning Archdemon's 5 second cooldown on its "autokill hero" skill.  Atlanticore's shield protects against that.

I'd read about this on reddit, but it seems like it would be hard to get the skills synchronized properly.  That's where seeing a video helped.  Watch it yourself.

The key is the application of Revive crests to Atlanticore, along with having the lowest hitpoints (so he's targeted), but enough hitpoints that the Archdemon won't kill him via normal damage.  The Archdemon will hit him a time or two maybe, but it will be the demon's talent that kills him.  This needs to happen after the PD has amped everyone up to top speed.  The demon's skill can't kill Atlanticore under his shield.  Thus, if he gets killed, you know he's synchronized.  On second thought that does not make sense.  If Atlanticore dies, he synchronized wrong.  Not sure how it works.  Perhaps you just get a little lucky; it's a 50% chance that it's synchronized, and that's enough for 1 time in 2.  I know there is a brief pause before a hero revives, so maybe that can change the timing a little.

I decided to try it.  I had five Atlanticore cards, so no problem getting a new one.  He got War God 2 for his talent.  Yawn.  I put in Heaven's Wrath 3 instead, since I had it sitting around unused.  But it still won't matter since the Archdemon can't be stunned.  Then I skillbooked him to level 100, and enscribed him to level 51.  This allows level 3 crests.  I gave him level 3 Revive crests.

Special Ops Atlanticore

The rest of the team is the normal "amp up and heal" guys -- PD, Cupid, and Druid.  Then there is Death Knight for anti-stunning (not sure if he's needed or not, but I reddit said use him), and Succubus for getting those 500000 damage procs.  (I need to compute if Phantom King might be better.  It depends on the amp-up level.)

On my first try, the Archdemon killed Atlanticore before I hit Invincible.  That doesn't achieve sync, so it only lasted 30 seconds or so.

My second run went for almost two minutes before something went wrong.  Then the archdemon killed Atlanticore a second time, and proceeded through my group.  I wasn't paying attention -- was typing this -- and I don't understand what happened.

Decent damage

I'll be working on it.  Next time, slowdown crests for everyone.
