Charm Collector

The Charm Collector is an NPC that, similar to the Witch Doctor or Dryad, arrives as soon as the Citrine Gladiator is defeated, there is a valid house available, and nobody else is waiting to move in. He sells several types of luck-themed items, each with its own availability conditions. He can also bless the character for 5 minutes at a time, meaning that mana is always full, critical hit chances are doubled, and nothing else can deal a critical hit upon them.
