  • General Rough Runestone and Quality Rough Runestone can be bought from Rune Seller at prontera168228 or auction_0316541.
  • Some materials can be gotten from Merry Badger Weekly Special.
  • Up to 60 of each kind of rune can be in the inventory at once, except for Turisus, Asir, and Pertz which doesnt have any limit.
  • If a successful creation would leave over 60 runes in the inventory, the creation will not progress. If this happens, a Rough Runestone will still be consumed, but no other ingredients will. For instance, if 3 Hagalas Runestones are created while having 59 Runestones of the same type, the creation will not progress, but a Rough Runestone will still be consumed; if 1 Hagalas Runestone is created while having 59 Runestones of the same type, the creation will proceed as usual.

Skin of Stone

  • Alt: Stonehard Skin
  • Rune: Hagalas.
  • Effect: Hardens the user's skin to increase DEF and MDEF temporarily. Due to user's hardened skin, there is a 30% chance to break the weapon of the attacker, or to reduce its ATK by 25% for 10 seconds if the attacker is a monster.
  • Target: Self.
  • DEF and MDEF Boost: (JobLv × RuneMastery_Lv) ÷ 4

The higher the user's total Equip ASPD% is, the lower the boost. For example: 24% of increased Equip ASPD will make this rune increases ASPD by 3, but if there is a 40% of increased Equip ASPD, this rune will only grant 2 ASPD.
