Practice Bosses

Hey guys,

New to this subreddit but I wanted to try my hand at a few runs. I had a few questions though

• How do you guys practice bosses, do you use a mod to spawn yourself into that arena or do you play the game start to finish every time. For example I wanted to try malikeith, do I need to do the entire game at SL1 to get there or is there a smarter way of doing this
• if you are using a mod to get to a certain point how do you guys tryout different builds etc

Thanks!
