I think a few elements of that analysis probably should be changed.

1. The Ancient Ent's wasp swarm damage should also be effected by the difference between attack and defense, so it's not actually 63 on average (41 at range, actually).

2. Ignoring critical hits overly disadvantages the ancient ent - and here's why: the ancient ent does 100-140 damage. The Archdemon does 88-99 damage. So a critical hit for the ent does 210 damage, or 1.75 times its average damage. A critical hit for the archdemon does 149 damage, or 1.6 times it's average damage. So even though both crit at basically the same rate, the ancient ent benefits more from it.

3. Ancient ents get a +10 defense bonus from defending. So if the ancient ent simply sits there defending, it only takes about 75 damage when the archdemon attacks, and retaliates for about 63. So the Ancient Ent can actually just sit there defending and either stalemate or win with greater odds than if it takes initiative and launches attacks of its own. Over 6 rounds defending, the ancient ent would take about 2 critical hits and 10 regular (including counter-attacks) for about ~988 damage; it would give about 2 critical hits and 10 regular for about 850 damage (significant overkill).

4. Wasp Swarm cannot be retaliated. Ancient Ent should use it.

If the ancient ent and archdemon just sit there swinging at each other, every 2 turns the ancient ent has been hit 4 times (for about 408 damage), and has hit the archdemon 4 times (for about 252 damage). As DGDobrev showed, this ends in 7 rounds with ~74 health left to the ancient ent. And a noticeable portion of the time, due to random variations in damage and critical hits, the AD will even win.

If the archdemon just parks itself next to the ancient ent and starts swinging, but the ancient ent only uses it's abilities, then every 2 turns the ancient ent is hit twice (for about 204 damage), retaliates the archdemon twice (for about 126 damage), and hits it with a close-range wasp swarm once (for about 82 damage). So overall, the AE takes 204 damage and does 208 damage. So if they repeat this pattern for 6 rounds, then in the 7th round the archdemon hits, is retaliated, then gets hit by wasp swarm... the archdemon has done ~714 damage and has taken ~769 damage. The archdemon's chance of victory is less than one in a million in this case.

If the archdemon is a little smarter, it will make use of the "wait" option to park itself precisely 5 spaces away from the ancient ent every time the ancient ent is about to launch a wasp swarm, then close in to strike afterwards - in which case the ancient ent is only doing 167 damage per 2 combat rounds. If this pattern goes on for 9 rounds of combat, the Archdemon does about 918 damage and takes about 772 damage. Closer, but still fairly clearly a win for the Ancient Ent.
