An Archer is someone who is an expert in range attacks(preferably in piercing range attacks)like magically throwing swords for example.
Traps for strategic advantage, long range damage to interrupt/stun mages, high DR to reduce hits taken from Warrior, effectively acting as bait/decoy for enemy tankers.

Archers must wear a Leather Hood and Leather Hide otherwise a hitting probability penalty incurs.
Archer Sample:

STR = 65 (104 with Dark Elf bow)
DEX = 200
INT = 38 (For Summon Creature [nice to use when trying to clean pits)
MAG = 10
AGI = 700
VIT = Place all remaining points here.
