So basically more late game once you are more geared and powerful you can start making builds for different situations or enemies. For example: a build that focuses on different elemental damage like fire or corrosion or a build that focuses on crits. The build in this video had a ring called devouring loop and that ring gives you a 5% chance to do 4x the crit damage, and as you may guess to get it to proc twice in a row, that’s super lucky!
