The boss from Sword Of Mana, he is found in the sealed cave. here are some tactics to destroy him:

Strategy: Ugh, this guy is so darn annoying. In all honesty, the smart
thing to do here is not fight him in close range combat, due to his Scythe
here follows where ever you go and circles around him like a shield
almost. It won't do much damage to you, DEPENDING on if you've been
training and upgrading your Equipment, but as for the Heroine, don't
bother with her. She'll probably be taken down in the first 5-10 seconds
of the fight and it's pointless to revive her. Other than his damn Scythe,
Lich releases Blue Fireballs that have faces and sort of home in on you,
plus if you get close to him, he uses what looks like Wind Slashes to hit
you from his hand. I suggest you use the Bow or some other long range
Weapon on him and as for Magic, definitely go with the Knuckles and Wisp
or any other Weapon that lets you throw Magic at long range. Either way,
just keep your assault up on him and he'll easily fall
