Yoooooo look at him!
Kinda had nothing to do tonight so decided to make him in FEH
Nightfall - 16 Mt, gives Special Spiral and if unit is not adjacent to any allies grants +7 Atk to unit and inflicts -7 Atk on foes during combat, heals 10 HP after combat.
(Tried to simulate his W ability with his weapon, in game it gives him a shield which he can consume for health later, thats where the Atk debuff and the heal come from, Nightfall is the name of his mace in game)
Obliterate - 2 CD, boosts damage by 60% of units Atk, nullifies Damage Reduction effects.
(That is the name of his Q ability in game, which does more damage if the enemy is isolated, kinda used that as an excuse to give him the nullify effect)
Darkness Rise - After unit has participated in 3 combats (player phase or enemy phase), deals 7 damage every start of turn to foes within 2 spaces and inflicts Gravity on foes, grants +5 Atk.
(This one mimics his passive ability, which he needs to land 3 abilities or auto attacks on an enemy to activate a damaging aura around him, also his passive gives him more auto attack damage thats why it gives +5 Atk (the Atk increase works like the beast unit increase, not treated as a buff), also crammed in his E ability, which pulls enemies towards him, thats why it has a gravity effect)
Tried to think of something for his Ultimate (which transports him and an enemy to another realm, forcing them to fight one on one), but I couldnt think of anything.
I love Mordekaiser
