Can someone please tell me how to beat the 1st boss without taking damage? I tried different things and only once out of about 20 attempts have I gotten his health bar to yellow.
Don't use your candle. Candle allows him to track, attack, and dodge you.
Get a bomb refill before the fight.
Hit him in the dark after he uses his circle boomerang attack until health is at yellow. Spam sword.
Once yellow, avoid him until he uses circle boomerang attack. Slash boomerang hit him when he goes to pick it up. Run.
Once red, hit his boomerang and place a bomb.
