Senda

Quick strategy

Keep moving through the projectile patterns, use ranged damage during unsafe approaches, reflect the purple fan with the backpack, and save melee pressure for the repeatable openings between rings and vortices.

These fight notes come from a cited Early Access community walkthrough. The official Steam achievement confirms the boss and defeat objective, but timings, balance, and rewards should be rechecked after a game update.

Key mechanics to recognize

• Spinning melee attack with ring projectiles
• Purple fan reflected with the backpack
• Central damaging vortex and projectile spread
• Large moving rings
• Tracking ring added in phase two

Phase-by-phase plan

• Opening: move vertically through projectiles and use ranged attacks while Senda spins.
• Fan sequence: return the purple fan with the backpack twice.
• Half health: wait for a gap between the rings, roll inward, and take the short attack window.
• Phase two: repeat the learned patterns while tracking an additional pursuing ring.

Reported rewards

• Two loot chests
• The King's Left Mask, reported as a crafting material for Aetherium Heart

What is confirmed and what is reported

Steam officially names Senda in the Wind Slumber achievement and gives the objective “Defeat Senda.”

The Zephyr Fields, Aeolia placement, attack sequence, phase plan, and reward list are community-reported. Use the linked walkthrough as the evidence and allow for version changes.
