Demise (boss)

Part 1
This Battle is a 1 on 1 sword fight between you and demise thus shield bash is your best friend here. If you attack demise he will parry the first 2~3 hits of your combo before getting hit... and when he is hit he will try to counter attack soon after. Your best bet is to ether wait until Demise attacks... shield bash it then get a hit in... or break his parry, shield bash the counter attack then get a hit in. After a few hits land demise will kneel down wounded.. this is your chance to combo up a fury of hits to do great damage to him. Soon after he will get up be able to attack/parry again. Repeat until he falls.

Part 2
After he falls to the ground he will get up and use his magical dimension to create a thunderstorm... which he will use to channel his blade with lightning by raising his sword high above his head. While his blade is lightning attuned close combat will be risky due to his parry's stunning/damaging you. (Which also leaves you open for him to attack you) He can also attack you with the lightning at a distance by slashing in your direction (jump to the left or right to avoid this) but this makes him lose his "thunder charge" (but he can get it again and will get it again throughout the fight. Beware while he does attacking him will stun/damage you). To counteract this when you see thunderstorms in the back ground back up from demise and raise your sword high.. this will let you channel the lightning in your sword (Beware! if demise doesn't have a thunder charge and you try to get one he may charge at you to attack you quickly). Hit Demise with this lightning (in the same manner as a normal skyward strike) to stun him for a short time use that time to do as much damage as possible.

After enough damage has been done demise will fall to the ground again and the game will give you a chance to do a finishing blow. The first time will most likely miss but each time you do more damage afterword he will take longer to get up from the ground when he falls. keep at it and you will soon land the finishing blow.
