Lil bit from my experience

Archers are long ranged n criticalest they do high damg n heavy criticals u would want the last skill tree to bost criticals ice n fire dmg aswell as phy damg for skills u wanna focus on lv 21 n lv 25(i belive) the freezing arrow n fire one they do high damg n in skill tree three (passives) its boost its up i have also seen in forst skill tree the last one is sloth slows target by 10% which can be devastating for close range fighters such as i so far i havent seem a arch take advantage if that
