The Ruins of Nirah, a legendary dagger that makes you invincible mid-combo, buried at the end of one of Woolhaven's longest quest chains.
The Ruins of Nirah turns the dagger's biggest weakness into a strength: on the fourth hit of every combo, you cannot be touched. That single window of invincibility rewards the exact aggressive, in-your-face style the dagger is built around.
It is the legendary dagger, one of seven 
legendary weapons in Woolhaven. According to the wiki, its original name is the Ruins of Nirah, described as the dagger of legendary sharpness.
Getting it is the catch. The shard sits at the end of a four-step quest that bounces you between two bosses, a fishing rod, and a specific season.
This guide covers what the Ruins of Nirah does, the full quest to reach its shard, how the dagger class plays, and how to squeeze value from its invincibility frame.

Invincible on the fourth combo hit.
Finish the Charybdis and Scylla quest, then take the shard to Rami.
You dislike short-range weapons, the dagger's core drawback.The Ruins of Nirah is the legendary version of the dagger, and its effect is pure survivability. Per the wiki, you become invincible during the fourth hit of a combo, so a fully committed combo string carries a built-in dodge.
That matters because daggers are fragile. The dagger class trades range and per-hit damage for speed, which usually means getting close and eating attacks; the Nirah lets you push through one hit each combo without flinching.
Like all legendary gear it outclasses even Godly weapons. It is restored by 
Rami and can be forced to appear as a priority 
weapon on any crusade except Purgatory.
The Ruins of Nirah shard is the reward for a four-step quest chain that runs through two Woolhaven bosses and a fishing rod. Per the wiki, here is the full order.
Scylla, Charybdis's sister.
Fisherman at Pilgrim's Passage during Winter and give him some Wool to receive a spare fishing rod.The timing gate is the fishing rod. In practice the Fisherman only sells his spare rod at Pilgrim's Passage during Winter, so if the season is wrong you cannot finish the chain until it comes back around.
Daggers are the fastest weapons in the game and the shortest-ranged. The wiki lists a base dagger speed of 2, the highest of any class, paired with low per-hit damage that leans on landing many quick strikes.
The tradeoff is real. According to the wiki, the dagger's damage falls off in the later game and on higher difficulties, and many enemies can attack from outside a dagger's reach, which cuts combos short.
Its heavy attack helps. The dagger slams down a falling row of blades in the aimed direction, and the wiki notes a Godly dagger heavy attack with the 
Fleece of the Berserker can kill most Darkwood bosses in a single hit.
Build around finishing combos. The invincibility only triggers on the fourth hit, so the payoff comes from committing to full strings rather than poking once and rolling away.
Use the fourth hit as your dodge. When a heavy attack is winding up, timing your combo so the fourth strike lands during their swing lets you trade cleanly, which is far stronger than the base dagger's hit-and-run pattern.
Support it with damage. Because dagger damage tapers off late, pairing the Nirah with Tarot cards that boost weapon damage keeps it relevant, and it stacks naturally with fast-hitting curses for the ranged coverage daggers lack.
Across multiple runs the Ruins of Nirah shines most against bosses with big telegraphed swings. Learn the timing of your fourth hit, and you can stand inside attacks that would delete a normal dagger user.
The dagger is named for a fallen goddess. Per the wiki, the Ruins of Nirah became legendary after the death of Nirah, a goddess who died long ago.
Her death was a betrayal. The wiki states she was murdered by someone she trusted, which is the act that steeped the blade in legend under Kudaai's definition of altered fate and divinity.
That ties it to the wider set. Every legendary weapon in Woolhaven carries a story of a god's death, and the Ruins of Nirah is the dagger entry in that grim catalogue.
The Ruins of Nirah is one piece of a much larger Woolhaven weapon set. These guides cover the other classes, the bosses that guard shards, and the cards that keep a dagger dangerous.
