'Seven Knights Re:verse' (hereinafter SKRB) has seen the arrival of the Four Lords, 'Rin' and '(Old) Karma.' For those who enjoyed the original 'Seven Knights,' these are very familiar faces. They were heroes beloved by players at the time for their outstanding performance. Given that history, their appearance in SKRB has naturally captured the attention of players.

Rin brings a new status effect called 'Confusion' along with a 4-target attack, while Karma possesses skills that deal additional damage proportional to defense and mitigate incoming damage to allies. With both heroes arriving simultaneously, players are busy exploring their performance. KookminTree has analyzed the performance and optimal combinations for Rin and Karma.

Two gusts of wind shifting the PvP meta

Let’s start with Rin. As a Magic-type hero, the core gimmick is the 'Confusion' debuff. It forces attacks to miss with a 100% increased chance for a set number of hits. Crucially, a 'miss' means the damage still lands, but any secondary effects are negated. Rin applies this through basic attacks (45% chance) and 'Dragon’s Wrath' (100% chance). The number of missed hits varies by skill, with 'Dragon’s Wrath' forcing two misses. Basic attacks see the Confusion application chance increase to 50% after skill enhancement.

'Dragon Scales' is a 4-target magic attack that grants a 100% chance to reduce turn-based buffs by 2 turns—a godsend for clearing those pesky persistent buffs. Once fully upgraded, landing a critical hit boosts the skill's coefficient by 37% of magic attack. The transcendence effect unlocks at 6-transcendence, resetting the cooldown of 'Dragon Scales' if it kills an enemy.

Dragon’s Wrath is another 4-target attack. It hits twice at 70% magic attack power. If the target has 50% or more HP, it deals an additional 30% magic attack damage per hit. Upgrading it pushes the base to 90% and the coefficient to 42%. Note that the Confusion effect is applied regardless of target conditions.

The passive 'Red Dragon Breath' is a Swiss Army knife: it grants one resurrection, a shield equal to 67% of magic attack after using a skill, and a crit rate boost. The crit rate scales by 3% for every 350 attack power, up to 27% base (33% upgraded). At 2-transcendence, resurrection restores 100% HP and grants two stacks of damage immunity.

Next up is Karma. A Universal-type hero whose skills scale off both magic attack and defense. The basic attack targets a single foe, but once upgraded, it applies a 6% damage reduction debuff to 3 enemies for 2 turns. 'Sinful Fireball' hits 3 enemies 3 times, ignoring 40% of their defense, with coefficients scaling nicely with magic attack and defense stats.

The passive 'Fallen Immortal' provides a 3-hit 'Reduction' buff to all allies, lowering incoming damage by 20%. This refreshes after Karma attacks twice. Upgrading it increases the damage bonus for Universal allies to 15%, and 2-transcendence adds a 33% block chance for Karma. The real hook is the 'Patience' stack system, which builds up to 4 stacks when Karma is hit, fueling subsequent skills.

The 'Storm of Despair' is the centerpiece. It deals piercing damage to 3 enemies and heals the entire team for 31% of the damage dealt. Consuming 4 stacks of Patience boosts the attack and piercing power. At 6-transcendence, this skill evolves into an AoE attack.

Expect both heroes to shine in the Arena, Total War, and Guild Wars. Rin disrupts enemy status effects and counters tanky decks, while Karma ensures the team survives with consistent healing and damage reduction.

Both possess multi-hit skills, which are perfect for stripping damage immunity from heroes like Teo. Karma’s defense-ignoring, piercing attacks offer a different flavor of tank-busting compared to Melkire. Since their skills target 3 enemies before 6-transcendence, they are also highly viable in Monday-Wednesday boss raids and the 3v3 format of Guild Wars.

How should you build your team?

For Rin, pairing with Melkire is a natural fit. You could replace Yeonhee in the traditional Melkire/Yeonhee/Vanessa setup. You’re trading Yeonhee’s constant magic attack buff and sleep effect for Rin’s turn-based buff reduction and reliable Confusion.

Sleep is currently viewed by many as a 'useless luxury'—great for forced crits, but too finicky to time correctly. Confusion, while limited by hit counts, is a guaranteed negation of enemy shenanigans. Plus, Rin brings much-needed buff removal and superior survivability thanks to the built-in resurrection and shield.

Karma works best as a general-purpose utility piece, particularly in defensive compositions. 'Storm of Despair' provides a cycle of damage and healing that keeps the team alive. Mirror matches might be tricky, though, as defense-ignoring skills will cut through even the sturdiest Karma.

If you are running a 3-mage team with Nia, swapping Nia for Rin is a strong move. You exchange Nia’s 'Million Volts' stun for Rin’s Confusion, and since Rin is not a Universal-type, Rin benefits fully from Yeonhee’s magic attack passive, turning Rin into a legitimate damage threat.

Prioritize Attack for Rin, Defense for Karma

For gear, Rin’s passive crit rate scaling means you want to hit specific thresholds: 3,150 attack base or 3,850 upgraded for the maximum 27%-33% crit boost. These targets are easily reached with the Vanguard set and sub-stats, so don't over-invest in attack once you hit the cap.

Karma thrives on a Defense/HP setup—the 'Def/Def/HP/HP' build with the Guardian set is the way to go. Since Karma's skills scale with both stats, you get survivability and damage in one package. When it comes to skill upgrades, dump your resources into Rin first; Rin’s upgrades provide meaningful mechanical buffs, whereas Karma’s are mostly just stat bumps.
