Seven Knights Re:BIRTH: Rudy Castle Rush 13M Lina Guide

To reach 13 million points against Rudy in Seven Knights Re:BIRTH Castle Rush without cooldown delay accessories, switch off auto-combat and manually align your offensive buffs before every damage phase. Rudy's base defenses, barriers, and counterattacks severely punish uncoordinated skill usage. By using Lina's damage amplification to power your primary carry while matching Rudy's natural skill cadence, budget and low-spender accounts can surpass the 13M threshold.

Rudy Castle Rush Mechanics Without Delay Gear

High-end Castle Rush strategies frequently rely on cooldown delay accessories to stall Rudy's actions and prevent him from cycling defensive shields. Without delay accessories, Rudy acts on a predictable, uninterrupted timer.

Because you cannot delay his skills, you must pace your team around his defensive stance:

• Avoid Unbuffed Attacks: Hitting Rudy while his shields are active without active armor debuffs wastes high-damage skill cooldowns.
• Maintain Multiplier Uptime: Your main single-target damage dealer must strike exclusively when an armor debuff and Lina's offensive boost are active simultaneously.
• Rely on Aggressive Sustain: Lina replaces the need for defensive stalling tools by supplying sustained healing, allowing the rest of the team to focus on offensive stats.

Core Team Roles

Build your squad around single-target burst, armor reduction, and buff uptime:

• Lina (Primary Buffer and Healer): Keeps party damage high with active offensive amplification and sustains the squad through Rudy's counterattacks using heal-over-time skills.
• Primary Single-Target DPS: A high-scaling boss attacker equipped with critical damage and piercing gear to cut through Rudy's defensive stats.
• Armor Breaker / Debuffer: Applies defense reduction or damage vulnerability to ensure the carry does not stall against Rudy's passive resistance.
• Sub-DPS or Turn Buffer: Fills empty turn windows with secondary damage, stat auras, or cooldown utility.

Manual Skill Rotation Sequence

Turn off auto-combat before the battle starts. Follow this three-step sequence to ensure your primary damage skills never strike an un-debuffed target.

1. Phase 1 (Setup): Cast your debuffer's defense reduction skill first. Do not use pure damage abilities until the debuff lands.
2. Phase 2 (Amplification): Cast Lina's offensive damage boost immediately after the armor break is applied. Avoid casting her healing abilities during this step unless party health is critically low.
3. Phase 3 (Burst): Unleash your primary DPS unit's strongest single-target skill while both Lina's boost and Rudy's armor shred are active.
4. Phase 4 (Filler and Recovery): Cast secondary utility, filler attacks, or Lina's heal-over-time while your main carry's primary burst skill is cooling down.

If a rotation timing error occurs, pause your main carry's skill for one beat to reapply debuffs rather than attacking into Rudy with an unbuffed strike.

Equipment and Speed Tuning

Speed tuning determines whether your rotations function properly. Lina and your primary debuffer must have higher speed stats than your main DPS. This ensures debuffs and buffs are applied before your carry acts in a given turn cycle.

If your primary DPS unit acts before Lina, remove high-speed sub-weapons or gear from the DPS until the attack order realigns.

Tactical Mistakes to Avoid

• Attacking Refreshed Barriers Without Debuffs: Do not queue carry abilities right after Rudy casts his barrier unless your armor shred has landed.
• Clipping Lina's Buffs: Recasting Lina's attack buff before the previous instance expires wastes a turn. Let the buff run its full course while using filler skills.
• Failing Speed Tuning: Allowing your carry to outspeed your support units drops overall damage significantly across the encounter. Ensure support units always act first.
