As all 1v5s go, I’m sorry to say Baron loses. On top of their regular attack damage (which deals about 100 damage per hit), dragons’ attacks all have an additional on-hit effect that deals 7% of their target’s current HP as bonus damage. This means that Baron loses half of his HP in just four seconds.

After that, it takes 16 seconds of wet noodle fighting for the dragons to finally finish him off—by the end of the fight, the drake’s attacks only deal about 40 damage each because Baron’s current HP will be so low. All together, it will take the dragons about 60 hits total to slay Baron Nashor.

During this whole fight, Baron will deal 15k damage back… which is only enough to kill one Elemental drake, and that’s only if he’s big brain enough to target the right one. Each Elemental drake is a bit different, but the more important thing to know is that Cloud drake hits really fast, and Mountain drake hits slowly but is tanky. If Baron Nashor focuses Elder or Mountain drake, this would be a bad strategic choice because he won’t be able to kill either of them before he dies.

To increase his chance of winning (which is technically always 0), he should go for Wind drake first, which will die after he deals 13k damage. By comparison, he’d have to deal 15,000 damage to kill Mountain Drake or 31,000 damage to kill Elder drake.

But if Elder drake and Baron were to have an honorable 1v1 fight at Baron pit… well, Baron still loses.

Even more than that, Elder Drake’s HP regen is so high (250 HP per second) that Baron can’t even deal damage to him. So basically, Elder drake can take a nap, roast marshmallows, and ignore Baron for as long as he wants until he gets bored and decides to win.
