Loneblade Riab — guide

In short

Loneblade Riab is a Rare Attack champion from the Sylvan Watchers with the Force affinity. He lives off debuffs on the target and extra damage against enemies already under Decrease DEF and Weaken, which is why his Clan Boss and Arena scores are far better than his dungeon numbers. Build him as a pure crit nuker, aimed specifically at Clan Boss and Arena.

Strengths

• Dagger Storm (A2) hits twice at 2.9× ATK, first buffing himself with Increase C.RATE 15%, then placing Decrease DEF 30% and Weaken 15% for 2 turns at 75% chance once booked — offense and setup in one button.
• The passive Savage Killer adds 5% damage per hit against targets under Decrease DEF or Weaken, and another 10% when both are up, so his own A2 feeds his damage.
• Both debuffs boost the whole team, not just him — every other damage dealer hits harder.
• A1 Illusion of Blades hits twice and fills 5% of his own Turn Meter per crit hit, which adds up nicely at 100% C.RATE.

Weaknesses

• Rare-tier base stats: 1,299 ATK, 96 SPD, 12,060 HP and 925 DEF — everything has to come from gear.
• A2 sits on a 5-turn cooldown (3 when booked); outside of it his damage is average.
• No survivability tools at all — focused fire deletes him.
• Force affinity struggles into Spirit, hurting both damage and debuff reliability.

Where to use

Main home is the Clan Boss (3.0): Decrease DEF plus Weaken and the passive are a real damage gain for the team. In the Arena (3.0) he works as a second nuker/debuffer who strips defence before your main nuke lands. Chimera (2.5) is acceptable. Hydra (2.0) and Faction Wars (2.0) are filler only. Doom Tower (1.5), dungeons and Hard content (1.0) are not his field — he simply doesn't carry there.

Stats and gear

Priority: 100% C.RATE → 150–200% C.DMG → 3,000+ ATK → 170–190 SPD → 150–200 ACC so the A2 debuffs actually land. SPD boots, C.DMG gloves, ATK ring. Sets: Fury, Savage, Cruel, Lethal for defence ignore, or Relentless if you want extra turns on the Clan Boss.

Masteries and blessings

Offense tree: Pierce Defenses for Arena, Boss Slayer for Clan Boss. Best blessing is Phantom Touch. Relic: Irethi Coronet.

Tombs

Book A2 Dagger Storm first — it carries the cooldown reduction, the extra debuff chance and the damage upgrades, and the whole kit hangs on that skill. Finish A1 and the passive with leftovers.

Verdict

A stopgap Rare nuker for early Clan Boss and Arena: useful while you lack real damage dealers, but he won't survive the transition.
