Dark Souls: Remastered · Weapon upgrade path
Crystal upgrade
Crystal upgrades reinforce weapons from +0 to +5, increasing physical damage and Strength and Dexterity scaling while reducing durability.
How it works
The source says the crystal path gives more physical damage than regular weapons and mainly increases Strength and Dexterity scaling while reducing durability. It describes this as suitable for short-term use: at +5 the weapon breaks and cannot be repaired. The stated maximum is +5.
