Combat Balancing Improvements

  • Double-Gun Switching  – The Flintlock, Blunderbuss and Eye of Reach have new wield animations and enforce a delay when equipping and switching between these weapons.
  • Fluid Swordplay – Missing a Cutlass swing no longer slows player movement down, ensuring a more fluid swordplay experience.
  • Eye of Reach Hipfire – Reduced accuracy when hipfiring the Eye of Reach. Under pressure you can still get lucky with a Hip-Fired Eye of Reach shot, however at mid to long range this is significantly reduced.
  • Weapon Knock back   – Flintlock & Eye of Reach shots will no longer apply knockback to enemies hit, Cutlass and Blunderbuss however will still retain their ability knock back players. Skeletons wielding Pistol, Blunderbuss & Eye of Reach have also had their ability to knock back players removed.
  • Weapon Reload Improvements  – Following the recent change to the Eye of Reach, now both the Flintlock & Blunderbuss reload the moment the hammer is pulled. This allows players to sprint sooner when reloading without restarting the animation.
  • Bullet Projectile Speed  – Bullets fired from a Blunderbuss or Eye of Reach now travel faster through the air, providing more predictable accuracy at range.
  • Weapon Damage Falloff – Bullet damage no longer decreases over distance.
  • Eye of Reach Damage  – Reduced Eye of Reach Damage by a small amount to ensure this weapon's damage is balanced following the improvements to bullet speed and damage falloff.
