Orphan's Call

A substandard set consisting of pieces that are individually good. None of the pieces are particularly difficult to get.

The set and gear is for physical attackers, although

Whitstan's Guard is good for anyone wanting cheap and easy block.

Wilhelm's Pride is a decent

Belt for life/mana leech. Most melee and archers may find

Magnus' Skin IAS useful.

Guillaume's Face is considered one of the best helmets for physical attackers or mercenaries due to it's high Crushing Blow chance, decent Deadly Strike chance, as well as 30% FHR and a little bit of strength to help with weapon requirements.

In short, you're getting these because you want easily obtained high-end gear, not because of the set bonuses.
