Introduction
Facing Odur, the first major boss in Thymesia, can feel like hitting a wall. His rapid attacks, deceptive combos, and dual-phase battle are a true test of your skills. But fear not—this guide will break down everything you need to know to take him down efficiently. From the best talents to upgrade, attack patterns to exploit, and potion management, we’ve got you covered.

Phase 1: Preparation and Key Upgrades
Before you dive into the fight, make sure Corvus is well-prepared. Investing in a bit of health through Vitality can help you survive longer, but the real game-changers are your saber and claw upgrades. Prioritize the following:

• Sharp Weapons Level 1 and 2: Enhances your saber attacks, allowing you to break through Odur’s wound bar faster.
• Long Claw Level 2 and 3: Increases claw damage and inflicts a bleeding effect that prevents Odur from regenerating wounds quickly.
• Long Dodge Level 1: Provides the distance needed to evade Odur’s wide-reaching attacks.
• Blessing Level 1, 2, and 3: Grants damage reduction and an extra life at max level, offering much-needed insurance in this high-risk fight.

Combat Strategy for Phase 1
Odur’s first phase is all about managing distance and timing your attacks. He typically starts with a series of three-hit combos or a powerful kick. The key is to bait out these attacks, dodge to the left, and counter with a full saber combo followed by a claw attack. Holding down the claw button allows you to execute the Reave ability, stealing a plague weapon for additional damage.

• Dodge and Counter: Dodge left whenever Odur finishes a combo to create an opening.
• Saber and Claw Combo: Use saber attacks to lower his wound bar, then switch to claws to drain health.
• Timing Matters: Watch for his stagger animations; this is the best time to unleash a full combo.

Phase 2: Dealing with Odur’s Enhanced Moveset
The second phase is a different beast entirely. Odur’s attacks gain additional speed and he starts incorporating five-hit combos. During this phase:

• Avoid Using Claws for Mobility: Unlike in phase one, using claws to cover distance will often leave you exposed. Stick to dodging to the left.
• Utilize Miasma: If you’ve unlocked the Miasma plague weapon, use it liberally. It grants a superior dodge effect, making it easier to evade Odur’s flurry of attacks.
• Critical Attacks: Odur’s critical strikes are signaled by a red glow. You can either dodge these to the left or use feather attacks to interrupt them momentarily.

Key Mistakes to Avoid

• Dodging Backwards: This often leaves you vulnerable to follow-up attacks. Always dodge to the sides.
• Overusing Claw Attacks: In phase two, relying too much on claws for mobility can lead to getting caught mid-animation.
• Ignoring Potions: Make sure to upgrade potion quantity and health recovery early on.

Optimal Potions for the Fight
The standard potion works fine but upgrading the quantity is crucial. If available, switch to the Long-Lasting Potion for sustained healing throughout the fight.

Conclusion
Defeating Odur requires patience, precise dodges, and a strategic balance between saber and claw attacks. By mastering these mechanics and avoiding the common pitfalls, you’ll find the battle not just manageable but a satisfying challenge. Best of luck, plague doctor, and may your dodges be swift and your parries precise!
