Inferno tactics.

How can it lose to Hippogryphs? On the first turn, you delay, and then you attack twice in a row... or attack once and then fly away... if you're lucky with the terrain, you can win without losses, but if not... anyway, it should be checked... I bet on Archdevils against Hippogryphs, what about you?

Okay, let's figure out how to conduct a battle...
In my opinion, it is correct to compare the strength of troops under the following conditions:
1) the same number of monsters
2) heroes with attack and defense skills set to zero
3) heroes without secondary "attack" and "defense" skills
4) heroes with the same morale (morale should be zero)
5) heroes without artifacts
6) heroes do not use magic during the battle.
I think that's all...
These are needed so that we compare the monsters themselves, and not various battle tactics...
Yes, the Devil without a mark is a very powerful weapon... but the Hippogryph has a very good ability (I think everyone knows it)... if you want, I can give you a link to where very smart people conducted a comparison... it's interesting to read..
I hope I made myself clear. By the way, what we are talking about is off-topic!
And to avoid this, a post on the topic:

In my opinion, a very good tactic for Inferno is a rush... because in the first week you can really get Ifrits, in the second week upgrade them and go to the neighbor before he builds level seven...

Yes, I apologize... the Hippogryph loses to the Archdevil in 60% of cases... I apologize for the misleading information...
