Minor Pulse Rift
A Minor Pulse Rift rooted in the corrupted sewers beneath Prontera, where parties purge Immortal Bug Eggs and face a twisted Golden Thief Bug in exchange for Chronocite rewards.
Blight Culvert Instance
Blight Culvert is a Minor Pulse Rift. Entry is made by using an Echo Rift Stone-the stone opens a random Minor Pulse Rift, which may be this instance.
- Only the party leader can use the stone successfully.
- Solo players must still create a party before using the stone.
- Only party members present when the stone is used will have the instance created for them.
Rift Stones drop from monsters globally; see Obtaining Rift Stones for drop rates.

- Instance Time Limit: 2 hours
- Map Name: 1@prtc (Prontera Culvert)
Ymir instructs you to destroy all Blight Bug Eggs of the Worldbreaker (count varies by difficulty: 3 Easy, 5 Veteran, 7 Nightmare, 9 Hell, 12 Torment). They were the cause of humanity’s extinction in this universe. A 1 in 4 chance spawns 3 Worldbreaker Bug Clones and a Prime Blighted Egg-destroy the egg to kill all clones. Once all eggs are cleared, the Worldbreaker Bug appears at the center; you have 25 seconds to enter the battle zone before poison gates seal the area.

Party Rewards
Rewards in this rift come from two layers:
Completion rewards (per character): party members online and on the instance map receive guaranteed Chronocites and get completion roll chances (Entropy Codex / Blacksmith Blessing).
Rift boss drops: while clearing mobs, Paradox Shards can drop via two independent rolls:
- Bundle roll (5x Paradox Shard): 0.2% for the killer; 0.1% for other party members.
- Single roll (1x Paradox Shard): 1% / 3% / 5% / 7.5% / 10% (Easy - Torment). On Torment, party sharing is enabled at 50% of the killer chance.
For the global reward rules that apply across all Pulse Rifts, see Rift Rewards.
| Item | Type | Description |
|---|---|---|
 Chronocite | Currency | Used to buy items from the Pulse Rift Shop Manager. |
 Paradox Shard | Currency | Core currency dropped from Rifts and used to enchant end-game gear. |

Strategy Tips
- Assign one player as a dedicated egg-killer during the boss fight.
- Avoid allowing the egg count to reach 10.
- If your party has strong DPS, maintaining fewer than 4 eggs may be manageable.
- If Worldbreaker Bug Clones (mob 30006) spawn, seek the Prime Blighted Egg to kill all three at once. The clones have high attack and will pursue anyone they aggro.
