[3.27] ❄️ Icicle Mines Deadeye ❄️ Cheap / League Starter / Fast Mapper / 1st Day T16

What changes do we need to make to comfortably run T17s?
What map mods to avoid etc
iirc ground dots etc was such a pain
and does anyone have an estimate of how much damage or investment to farm constantly t17 bosses?

Thank you
