Start story point at first city(world tier 1) —> reach across the river checkpoint
Don’t shoot any enemies as they spawn in just run right to the end up the stairs then do circles so there all bunched up you should have around 25-30 to shoot at on first pile up then around 15 then 10 and being on tier 1 they should die fairly fast
For skill accolades that you don’t need to kill just inflict status effects just play on the highest tier your currently on and run around in circles letting your skills hit them everytime the effect runs out, Youl also gain tier experience too for better loot
