https://pastebin.com/W2EicfqM Can be Guardian or Occultist, fantastic clear early league on low investment and builds up into a great bosser. Doesn't quite have the damage for wave 30 but everything else doable.

EDIT: This is how I determine a good leaguestart build btw, since there is always disagreement on exactly what it means and what it should be able to do. I am not claiming these builds will kill endgame bosses day 2 with zero investment, they are meant to be approachable at low end and powerful at high end.

• Must be able to clear act 10 and enter maps in first 10 hours of league without buying gear, except to cap resistances or raise life above the mapping minimum.

• Early mapping feels smooth with minimal investment, easily acquirable upgrades.

• Has a defined upgrade path reaching well into endgame.

• Feels good to play at any point along that path.
