Just came across a slightly confusing naming inconstancy for evolution items for gear.
In the marks shop and normal shop - You can buy Lesser, Greater and Major Relics.
Eveline - Exchanges Tier I, II, III and IV Relics
Upgrading page for an item or the complete inventory page dropdown list - Doesn’t even mention the type of relic. It just mentions uncommon to rare, rare to epic, epic to legendary and legendary to mythic.
This naming makes it confusing to work out what to aim for.
