Impoved R1 R2 build. Can solo every map.
Astral Ranger - Lv.120
More damage, better durability, still cheap and very easy to use. Just press R and chill.
A bit more damage than on classic build, way tankier because of 10k+ strength and armor from agility, so you can survive even without stacks from armor. Cheap due to mythical R1 R2 weapon which can be used until you find Darnassus Bow or Celestia (this bow the best) and unexpensive other items.
Performs well in Serengaard because of Glyph of the Gourmand and can stay afk if you leave macros/clicker on ult.

All you need is to press a R button and walk around. Before boss fights use W on them for damage enhance and extra attributes.
