Guild Raid in RF Online Next runs as a five-round gauntlet, and on Hell difficulty each round hands out a larger guild payout than the one before it. The valuable personal loot is stacked at the back end, so the last two bosses are the ones worth organizing a full roster for.
Quick answer: Clear all five Hell rounds in order — Mecha Infernal Larva, Mecha Lapis, Mecha Tweezer, Vestus, then Paimon. The Epic skillbook “Passive – Unassailable (Bound)” drops from Round 4, and the Tier 3 Prime weapon “Prime Blue Flame Force Charger II” drops from Round 5.
Hell mode round order, bosses, and guild rewards
The boss lineup is fixed, and the guild reward climbs by 1,000 per round. That means a partial clear still pays out, but stopping early costs you the two rounds that carry the Epic and Prime items.
| Round / boss | Guild reward | Personal drop |
|---|---|---|
| 1 — Mecha Infernal Larva | 16,000 | Ceramic-Coated Chest Guard (Bound) |
| 2 — Mecha Lapis | 17,000 | Fine Accessory Upgrade Kit (Bound) |
| 3 — Mecha Tweezer | 18,000 | Epic Weapon Blueprint (Bound) |
| 4 — Vestus | 19,000 | Passive – Unassailable (Bound) |
| 5 — Paimon | 20,000 | Prime Blue Flame Force Charger II, Rare Sweetie Body (Bound) |
A Hell run comfortably supports a large roster — a group of 42 members clearing together is normal, and the raid is built around that kind of headcount rather than a tight party. Guild raid difficulty also extends past this ladder, with a Hell 2 tier added on top for guilds that outgrow it.

The single mechanic that decides whether your Sacred Weapon contributes for the whole raid is placement. A deployed Launcher fires on its own from range, so it does not need to sit near the boss to do damage.
Note: once durability runs out mid-fight, redeployment is not instant. Losing a Launcher on Round 2 means fighting the later bosses without it.
Round 4: The “Passive – Unassailable” Epic skillbook from Vestus
Vestus is the first boss on the ladder that drops an Epic-grade skillbook. “Passive – Unassailable (Bound)” appears on the Round 4 results screen alongside the 19,000 guild reward, and it carries a market value of 21,000 diamonds.

The (Bound) tag matters. Bound equipment cannot be fed into Material Conversion, so this is a book to slot into your build rather than a resource to break down.
Round 5: Prime Blue Flame Force Charger II and the Paimon rewards
Paimon closes the run and pays the largest guild reward at 20,000. The headline personal drop is the Tier 3 Prime weapon “Prime Blue Flame Force Charger II”, with the “Rare Sweetie Body (Bound)” costume part arriving in the same results window.
A Prime weapon at this tier is the reason the raid is worth running at Hell rather than a lower difficulty. Prime gear carries added fixed and percentage stat bonuses on top of the base item, and buying an equivalent T3 Prime piece on the market runs far higher than a normal T2 or T3 Epic listing.

How to confirm your Guild Raid rewards landed
Every round ends with a Guild Raid Results window that splits guild rewards from personal rewards. If the item you were chasing is not listed there, it did not drop for you on that round — there is no separate delivery step to wait on.

Close the window and the group moves straight into the next round. For the league payouts tied to your guild’s standing, open the Guild Raid menu and check the Gold League Reward Info panel, which lists what the bracket pays independently of individual round drops.

Unbound drops from the raid feed into the guild auction, where materials such as Epic Weapon Blueprints and upgrade kits get bid on internally and the diamond proceeds are distributed to attendees through the Guild Vault. Bound items like the skillbook and the costume part stay with whoever they dropped for, which is why Rounds 4 and 5 are the ones individual members care about most.
