ESO Fanthor Keep Supply Crates are the new Jerall Pass resources used to support higher-rank keep upgrades. You can buy them, craft them using vendor recipes or obtain them from named bosses, then hand them to the Keep Master at Fanthor Keep. The important detail is the destination: the crates go to the keep itself, not to its mines, mills or farms.
This system is being tested for Update 52, with Jerall Pass planned to become permanent on 27 January 2027. It is not the same as the established Cyrodiil upkeep mechanics, and the PTS has already adjusted how much each crate contributes to an upgrade.
How to get ESO Fanthor Keep Supply Crates
There are three ways to get Fanthor Keep Supply Crates in the PTS build. You can purchase them from Siege Vendors at the alliance entrances and resource areas; buy a blueprint and make them yourself; or loot them from named bosses in Jerall Pass. The crafting route uses Blacksmithing, Provisioning and Woodworking rather than a single generic station.
| Method | Where to start | Practical catch |
|---|---|---|
| Buy | Siege Vendors at alliance gates or resource locations | Prices and stock must be checked in the current PTS |
| Craft | Buy the appropriate recipe from a Siege Vendor, then use its matching crafting station | Material requirements are not reliably published in the official summary |
| Boss drop | Defeat named bosses in Jerall Pass | No guaranteed per-boss drop rate is confirmed |
For players already set up for crafting, buying a recipe may be more useful across repeated supply runs than relying on the vendor’s ready-made stock. For a group trying to rescue a keep quickly, buying an available crate may save a trip to a crafting station. Neither is a proven cheaper option until the final vendor prices and materials are known.
Where to deposit ESO Fanthor Keep Supply Crates
Take Fanthor Keep Supply Crates to the Keep Master inside Fanthor Keep. ZeniMax’s official Jerall Pass feedback thread specifically asks PTS players to verify that resources can be deposited at the keep and not at the mining outpost, lumber mill or farm. If you are looking around an outer resource site for a turn-in interaction, you are in the wrong place.
- Enter Jerall Pass on the PC/Mac PTS and acquire a crate using one of the three methods above.
- Travel back to Fanthor Keep when your alliance can safely reach the keep and locate its Keep Master.
- Use the Keep Master interaction to deposit your available supply resources.
- Check the keep’s upgrade progress and watch whether its upkeep changes as the rank rises.
Be realistic about the combat around the destination. The whole point of Fanthor Keep is that three alliances contest the same location. A planned supply run can be interrupted by enemy players, and holding the keep matters as much as delivering a single crate. Organising deliveries with people who are defending the keep makes more sense than relying on a solo run through an active battle.
How ESO Fanthor Keep Supply Crates support Rank 5
Fanthor Keep and its linked resource objectives can reach Rank 5 in the test build. The extra ranks are not simply permanent milestones: at ranks 3, 4 and 5, upkeep can cause the upgrade level to fall when resources are not maintained. A keep that was built up earlier therefore still needs supplies later.
The initial test version made that upkeep harder to sustain. In the Week 2 PTS patch, ZeniMax raised the deposit value of Fanthor Keep Supply Crates from 10 to 100 resources to make higher levels more attainable. This is a tenfold increase in its stated contribution, but it does not mean a single crate automatically provides a full Rank 5 upgrade.
| Keep rank | PTS upkeep situation |
|---|---|
| Ranks 1–2 | No new high-rank upkeep requirement is specified in the notes |
| Rank 3 | Upkeep applies; deliveries help maintain progress |
| Rank 4 | Upkeep applies; watch resource levels |
| Rank 5 | Highest PTS upgrade rank, also subject to upkeep |
Fanthor Keep Supply Crates, Jerall Marks and scrolls are different
These resources overlap in the same PvP zone but do separate jobs. Fanthor Keep Supply Crates support the keep upgrades; Jerall Marks are the PvP currency earned from Bounty Board quests and bosses; offense and defense scrolls are consumable character buffs purchased with that currency. A crate deposit is not the same transaction as buying a personal buff.
Named bosses matter in both systems because they are listed as sources of Jerall Marks and Supply Crates. That is a reason to investigate them, not a reason to assume every boss awards the same quantity of either reward on every kill.
ESO Fanthor Keep Supply Crates FAQ
Can you craft Fanthor Keep Supply Crates?
Yes. The PTS supports Blacksmithing, Provisioning and Woodworking variants, with their recipes sold by Siege Vendors at the entrypoints. Check the current recipe tooltip rather than relying on a made-up fixed material list.
Can you turn crates in at a farm or mine?
No. ZeniMax has specifically identified Fanthor Keep as the deposit point and the outer resource areas as locations that should not accept the turn-in.
How many Fanthor Keep Supply Crates do you need for Rank 5?
The final per-crate requirements, upkeep rate and complete upgrade formula are not established by the official materials reviewed here. The reliable figure is the Week 2 increase to 100 resource value per crate; the number needed depends on the current keep situation and subsequent PTS balancing.
