You probably don't know about the devastating blade of the Dungeon Lords - the creature kills 1 unit + adds damage from its attack, which makes it even more deadly than the Grasping Strike.
In general, talking about a 1-on-1 battle in a turn-based strategy game with armies, heroes, upgrades, and artifacts is pointless.
There are usually not many strong creatures in a squad, and even 1 creature can significantly influence the outcome of the battle.
