Hello.You might want to know how to defeat bosses the easy way. Here is a list of steps:
Step 1: Work in groups. This may seem easy, but some people always brave out. You cannot afford to do that.
Step 2: After you gathered around some people, get a gun or bow. If you are a warrior, use your ranged skills. This is good as the boss will not get a chance to attack you.
Step 3: Get a backup in hand. That way when one person dies, the other will fight the boss. If you don't, the boss will regain health.
Have fun fighting!!!
