11Overview22The Ruin Guard is the final boss of the Moonlit Forest and the toughest opponent in Starsand Island. It is a large mechanical construct found in Moonlight Meadow, the deepest zone of the dungeon. Defeating it completes the Expert Explorer trial and unlocks the Luna Deer the only free permanent mount in the game.44Unlike the Crystalith and Glintortle, the Ruin Guard only exposes its weak point (the top of its head) during two of its four attacks. The other two attacks require immediate evasion. This fight demands extreme patience. Attack only during safe windows and spend the rest of the time dodging.66Quick Reference88DetailInfoLocationMoonlight Meadow (final zone of the Moonlit Forest)Explorer rankExpert Explorer trial (final boss)Weak pointTop of its head, only exposed during 2 of 4 attacksRecommended weaponPlume Bow or Crossbow with Bomb ArrowsAmmo needed20-30 Bomb Arrows + 50+ standard arrowsKey mechanicDaze state, head drops to arena level for double damageDifficultyVery Hard (hardest boss in the game)RewardLuna Deer permanent mountRepeatableNo (one-time encounter, resets to full health if you retreat)1010How to Reach the Ruin Guard1111The Ruin Guard is the culmination of the entire Explorer profession quest chain:1313Complete the Junior Explorer trial (defeat Crystalith).Complete the Intermediate Explorer trial (defeat Glintortle).Complete the Senior Explorer trial, visit Youfang in his temple near Cloudrest Lake.

Shoot the six lights floating above torches with Fire Arrows.Cross the bridge to Moonlight Meadow. The Ruin Guard awaits.1515Attack Patterns1717The Ruin Guard has four distinct attacks. Two create safe windows to attack the weak point (head); two require immediate evasion with no safe opening:1919Safe Windows (Attack During These)2121AttackDescriptionTelegraphHow to exploitGreen Charge Vines (BEST OPENING)Charges green vine energy in both hands. After the animation, damaging vines spawn under your feet.Longest charge animation of all attacks. Head weak point glows the entire time.Pump arrows into the head during the entire charge-up. Move immediately when the animation ends, vines spawn at your position.Flying OreSlams the ground and levitates a rock above its head, then launches it at you.Rock floats above its head. Head weak point glows for several seconds.Shoot the head during the charge-up window, then dodge the rock when it launches.Flame BeamFires a sustained laser/fire beam that slowly rotates toward your position.Red charge appears over its head. Head weak point is exposed.Strafe at distance while firing arrows at the head. The beam rotates slowly enough to avoid by strafing.2323Unsafe (Dodge These, Do Not Attack)2424AttackDescriptionTelegraphHow to dodgeGreen Charge SlicePulls green energy into one hand and fires a slicing projectile straight at you.Green energy visibly gathers in one hand.Strafe continuously and back away. Do not attempt to fire back.Spin Slice (MOST DANGEROUS)Twists its body and spins across the arena like a blender, lunging at you.Almost no warning. Watch for the body twist: the instant you see it, run.Equip Roller Skates and sprint away. Put away your weapon for maximum speed. Never attack during this move.2626Daze Mechanic (Double Damage)2727When you deal enough damage to the head during safe windows, the Ruin Guard becomes temporarily dazed. Its head drops to the center of the arena at ground level. During this state:2929You deal double damageThe head is at point-blank range, you cannot missDump your strongest charged Bomb Arrows directly into the skull3131The daze state is the most important damage window in the entire fight. Save your Bomb Arrows for these moments if possible.3333Stun-Lock Rotation3535The most efficient strategy against the Ruin Guard is a stun-lock rotation using Bomb Arrows and standard arrows. Rather than firing Bomb Arrows continuously (which wastes expensive ammo), alternate between a single Bomb Arrow for the stun and rapid standard arrows for damage.3737Position: Stay at mid-to-long range with a clear line of sight and room to sidestep.Initial stun: Fire one Bomb Arrow at center mass during a safe window to trigger the stagger state.Damage phase: Immediately switch to standard arrows and fire rapidly while the Ruin Guard is immobilized.Re-stun: Before the Ruin Guard fully recovers, fire another Bomb Arrow to restart the stagger cycle.Reset: If you miss the re-stun window, prioritize dodging and re-establish distance before attempting the cycle again.3939By using one Bomb Arrow per cycle and filling the gaps with standard arrows, you conserve expensive ammunition while maintaining consistent damage. With a Crossbow, the rotation is even more effective because the Crossbow has no charge time, letting you rapid-fire during each stagger window.4141Applicability: The same Bomb Arrow stun-lock rotation works against the other two large bosses in the game, the Crystalith and the Glintortle. For the Crystalith, use Blast Pellets from the Slingshot instead of Bomb Arrows for the same effect.4343Punishing Recovery Windows4545Two of the Ruin Guard's attacks have exploitable recovery animations that leave it vulnerable beyond the initial safe window:4747Flying Ore recovery: After the Ruin Guard launches the levitated rock, it pauses briefly before transitioning to its next attack. During this 2 to 3 second recovery, the head weak point remains partially exposed. Fire quick standard arrow shots during this gap for bonus chip damage.Flame Beam cooldown: After the sweeping fire beam completes its rotation, the Ruin Guard lowers its head momentarily. This cooldown window is your second-best damage opportunity after the full Daze state. Pump charged Bomb Arrows into the exposed head during the 3 to 4 second cooldown before it begins its next attack.4949Learning to exploit these micro-windows significantly reduces the total fight duration. Experienced players can chain damage from the initial safe window straight through the recovery animation without stopping.5151Ammo and Resource Management5353The Ruin Guard fight is the longest encounter in the game, and running out of Bomb Arrows mid-fight is the most common reason players fail. Proper ammo budgeting is essential:5555ResourceMinimumRecommendedNotesBomb Arrows2030-40Save exclusively for Daze phases and Flame Beam cooldownsStandard Arrows5080-100Use during safe windows for chip damage and stun-lock cyclingHealing food5 meals8-10 mealsChicken Stewed with Mushrooms (105 Energy + Battle Spirit) is idealSentry Bots35-10Deploy one at a time; stagger throughout the fight5757Prioritize Bomb Arrow conservation. Each Bomb Arrow is worth roughly 5 to 8 standard arrows in damage output, but only when used during Daze phases or Flame Beam recovery windows. Firing Bomb Arrows at the body or during unsafe attacks is a waste. If you find yourself running low on Bomb Arrows before the boss is at half health, switch to the stun-lock rotation using standard arrows and reserve remaining Bomb Arrows for Daze phases only.5858Recommended Gear6060ItemDetailsWeaponPlume Bow (minimum).

They do not deal extra damage to enemies).6363Step-By-Step Strategy6565Deploy Sentry Bots before engaging. They provide passive damage and pressure.Keep maximum distance at all times. Distance gives you reaction time to identify which attack is coming.Identify each attack as it starts. For the two unsafe attacks (Green Charge Slice and Spin Slice), focus entirely on dodging.Attack only during the two safe windows. Green Charge Vines (best opening), Flying Ore, and Flame Beam all expose the head weak point.Prioritise Green Charge Vines. This has the longest charge animation, giving you time for multiple charged Bomb Arrow headshots.When the boss is dazed, dump everything. Stop running and fire charged Bomb Arrows directly into the skull at point-blank range. This is your highest-damage moment.Expect to take hits. Even with careful play, the Spin Slice's minimal telegraph makes it hard to dodge perfectly. Keep healing food on your hotbar.Be patient. This is the longest fight in the game. Do not get greedy with extra shots. One extra arrow is not worth taking a hit.6767Rewards6969After defeating the Ruin Guard, it crumbles into a pile of junk and a broken altar appears in the center of the arena.
