Allagan Tomestones of Hermetics are not a currently active or historically implemented form of endgame currency within Final Fantasy XIV that players can obtain or spend. The term is primarily known from datamined information related to earlier versions of the game, suggesting it might have been a planned, placeholder, or ultimately unused tomestone type.
To understand the system such a tomestone would have belonged to, it's essential to grasp the general function of Allagan Tomestones in FFXIV's endgame progression.
Allagan Tomestones: An Overview
Allagan Tomestones serve as a key endgame currency, typically categorized during an expansion's lifecycle:

- Capped Tomestones: These are the newest and most potent tomestones, featuring a weekly acquisition limit. They are exchanged for the current highest item level gear available through this currency system. The specific name of this tomestone type changes with major patches (e.g., Allagan Tomestones of Comedy, Allagan Tomestones of Causality in their respective eras).
- Uncapped Tomestones: These are older or more common tomestones without a weekly cap. They are used for acquiring gear from a previous tier, catch-up gear, crafting materials, or items related to content from past expansions. Allagan Tomestones of Poetics are a persistent example, used for gear and items from expansions prior to the current one.
How Allagan Tomestones are Acquired
Players earn Allagan Tomestones by participating in various max-level activities. The type and quantity of tomestones awarded depend on the content's relevance to the current patch and its difficulty. Common sources include:
- Dungeons at the current level cap.
- Trials (both Normal and Extreme difficulties).
- Raids (Normal, Alliance, and Savage tiers).
- Daily Duty Roulettes, especially Expert, Level Cap Dungeons, and Alliance Raid roulettes.
- Other content such as The Hunt or specific Treasure Maps may also yield tomestones.
Spending Allagan Tomestones
Tomestones are exchanged with designated NPCs, typically found in major city-states or endgame hub locations pertinent to the current expansion (e.g., Radz-at-Han, Eulmore, Idyllshire, Mor Dhona).
Their primary uses are:
- Gear Acquisition: Purchasing weapons, armor, and accessories. Gear bought with capped tomestones usually offers a significant item level upgrade.
- Gear Augmentation: Sometimes, tomestones or items purchased with them are used to enhance tomestone gear to a superior version.
- Crafting Materials & Miscellany: Uncapped tomestones, in particular, can often be traded for specialized crafting materials or other useful items.
While specific "Allagan Tomestones of Hermetics" did not become an active currency, the framework detailed above illustrates the consistent system through which all Allagan Tomestones function in Final Fantasy XIV.
