Elden Ring Mohgwyn's Sacred Spear Notes & Tips

• Weapon Skill: Bloodboon Ritual.
• Bloodboon Ritual can hit targets from behind walls/objects and buffs the weapon with an effect similar Bloodflame Blade
  • The Buff adds a flat 30 AR of fire damage to the weapon regardless of weapon or stat level
  • The buff lasts for 20 seconds, which includes the cast time of the ability.  Effective use time is closer to 17 seconds
• This weapon cannot be infused with Ashes of War
• Mohgwyn's Sacred Spear can be upgraded by using Somber Smithing Stones
• Despite consisting of multiple hits, the Weapon Art is NOT affected by any multi-hit talismans, such as Millicent's Prosthesis.  However, the damage is still increased if you have already generated the buff prior to using the Weapon Art 
• Longest of the Great Spears.
• Causes Blood loss Buildup: 

   (55) 

  • The amount of Blood loss buildup also scales with Arcane.
• The Damage Scaling favors Arcane over Strength despite them both having a C rating at +10
  • This is because both physical AND fire damage both scale with Arcane.
