• Wooden Spears have the fastest cooldown; Netherite the slowest
• Can hit multiple enemies

Charge Attack

• Press and hold the secondary action button to use
• Damage is based on Spear material, the player’s view angle, and the velocity of both the player and the target
• While holding down the button, the attack goes through three stages before returning to idle:
• Engaged: The Spear can deal damage, knockback, and dismount mounted enemies if the speed is above the required thresholds
• Tired: Indicated by the Spear rotating to a vertical position and shaking. The Spear can deal damage and knockback (but not dismount) if the speed is above the required thresholds
• Disengaged: Indicated by the Spear being lowered, pointing downwards. The Spear gives damage but not knockback or dismount if the speed is above the required threshold

Texture Filtering

• New option in Video Settings
• Controls the method used to sample textures when they are viewed at an angle or from a distance
• Available values are "None", "RGSS", and "Anisotropic"
• The default depends on your graphics preset and hardware
• "RGSS" (Rotated Grid Super Sampling) is a shader-based filtering method that improves texture clarity at a moderate performance cost
• This is available on all hardware
• "Anisotropic" is a hardware-based filtering method that provides the best texture clarity
• The maximum anisotropy may be "2x", "4x", and "8x", controllable by a separate slider
