LoL. that’s the 1st archer build I try from tosbase, and that one is a troll build if you didn’t realise it yet
a2-sap3-falcon-cannon is current norm to go, if you want best damage and aoe from the build in higher level map.
But if you want to play and utilize better sapper without caring too much about min-max damage and synergy, a1-qs1-sap3-scout-cannon2 is good to go. With qs1, you will be able to agro the mob from safe distance and set the combo you want (punji or broom trap). Also cloak, fluflu, and camouflage have many use in many scenario that you can explore later
For the stat build, high dex or full dex is the meta for archer class right now, because damage and hp cvalue from gem and head acc are better than crit and evasion rate.
