How can I beat the final boss in Swordigo?

It's been a while since I played that game but I remember that fight.

I used to get back in the left corner and wait for him to come by. If he got too close I attacked him and then stepped back to the left corner.

Also I don't remember how it's called but you have blue magic you can throw at him you can use that while he is out of reach and you are waiting for him to come closer.

You should have the magic armour and mostly maxed all of your stats. Carry a potion with you and put the shadow trinket on your armour. The first boss you need to use dimension rift, if you manage to hit him when he it above you you can spam attack and he cant hurt you. For the final boss don't use magic bolts because he will almost always block them and reflect them back to you. make sure you have fire trinket on your sword. Jump over his head when he does his ground attack and run to the other side, keep doing this to slowly regain health with your shadow trinket. When you approach him try to get a few hits then run away. Continue to do this for a while and soon you will kill the boss.

I hope this helps.

Keep jumping over him and attack from behind. Make sure you have the fire trinket on your sword; it makes the sword stronger.
