The guild is run by the Guild Master who is also a customer. Note that he is no less likely to purchase anything you just bought from the guild than anyone else is.
The items sold by the Merchant's Guild depends on your Merchant Level.
Some weapons like Arma's Parts and Griff's Claws are not sold until the hero using them is recruited.
Initially the guild stocks 2-5 Tier 0 items and 1 Tier 1 item. Once you reach Merchant Level 4, Tier 0 and Tier 1 become unlimited and Tier 2 is accessed with 1 item in stock. Each consecutive time the previous Tiers become unlimited and the newest Tier stocks only a single item. There are certain exceptions to this rule:
- Giant's Fist, Spellclaw and Drill Arm remain in limited supply at Tier 4.
- There is no Tier 5 Arm Part.
- There are 2 Tier 5 Clothes.
Any item can be sold back to the Guild for 30% of the base value. High/Low price trends push this to 36% and 24% respectively, though still a considerable loss.
Fusion unlocks at Merchant Level 5 and can be used to craft powerful items that cannot be obtained through other means. For more information visit the Fusion page.
The guild master offers wordy tutorials for the topics.
- What is the guild?
- What can I do here?
- About merchant levels
- About the town
- About unknown items
- About fusion
These should be read on a first playthrough but can otherwise be ignored.
