Late-Stage Currency & Raid Material Demand for Relic Weapons
As relic weapon upgrades progress in Final Fantasy XIV, the later stages often shift from using common materials to Final Fantasy XIV Gil requiring raid drops, tomestone materials, and special crafting components. These materials typically become bottlenecks, creating strong gil-making opportunities for crafters, gatherers, and traders.

1. Tomestone-Based Crafting Materials
Relic weapons often require materials purchased with Allagan Tomestones, usually of the capped variety (Tomestones of Comedy in Dawntrail). These materials are used in crafting high-end components needed for relic progression.

Examples of Past Tomestone Materials:
Endwalker – Manderium Meteorites (purchased with Tomestones of Astronomy)
Shadowbringers – Thavnairian Scalepowder (Tomestones of Poetics)
Stormblood – Recollection-Related Items (Poetics)
⚡ Strategy:

If the current expansion's capped tomestones are used for relic materials, expect initial shortages and high prices.
Farm capped tomestones early before the relic upgrade releases and stockpile the needed items.
If an older uncapped tomestone currency is used, farm those in dungeons and roulettes for cheap Final Fantasy 14 Gil easy profit.
