I have one more question, because I don’t undersand it; Brutality.
Brutality makes your damage scale as your target's hp gets lower.
Usually I recommend to everyone as a base to run 25/50/25 ratio on your base stats. Meaning you dump 750 into Supremacy, followed by looking at how many offensive stats you have leftover. Let's say 500. Then you divide 500 by 4 = 125. So you put 125 Prof, 250 Deter, 125 Brutality. Hence the 25/50/25 ratio.
In my set I have lot of brutality. I have No idea how can I change it for bloodlust or determination.
You have to learn not to mix offensive and defensive stats.
Bloodlust is a defensive stat, so you cannot change brutality into that. Determination is an offensive stat, like brutality. You'll have to see on each gear piece at the bottom if they do offer the desired stat. Not all pieces can have any stat unless tier 3 gear.
Btw is Luck important stat too?
Don't bother with luck if u don't understand the beginnings yet. Just focus on the basis for now, you'll use Luck as you learn more
Here's a PvE ranged build too.
