Direct answer: You can use Power Dice 12 when upgrading general equipment (weapons, armor, and some accessories) in Flyff Universe — it covers upgrades from +1 up to +10 and is typically offered at the blacksmith upgrade NPC in Central Flarine (or the game’s equivalent upgrade NPC).

Where and how to use it

  • Upgrade NPC: Take the item you want to upgrade to the game’s blacksmith/upgrade NPC (for example, Boboko in Central Flarine) to start the upgrade process.
  • Valid items: Power Dice 12 is used for general equipment upgrades (weapons and armor) and can be applied across the +1 to +10 range.
  • Success and protection: Dice 12 provides a high success rate across that range, but from certain levels (commonly +4 and up) you’ll often also need or want Scrolls of SProtect (or similar protection scrolls) to prevent breaking on failure.
  • Drop / acquisition: Dice 12 is typically dropped by higher-tier monsters (Giants/Bosses) or obtained through events or content specific to your server/version. Availability may vary by server.

Practical tips (from community sources)

  • Use Dice 12 for initial and high-level upgrades when you want a single die that covers +1 through +10 rather than switching dice at thresholds.
  • For safer upgrading, combine Dice 12 with appropriate protection scrolls (SProtect / Low SProtect depending on level) and use recommended materials (minerals/erons) listed by the upgrade NPC instructions.
  • Players often reserve Dice 12 for expensive items because it covers the full +1–+10 range and has higher success probability than low-tier dice.

Example (quick forum-style note)

I used Dice 12 on a weapon from +0 to +6 with SProtect from the blacksmith NPC — fewer dice swaps and decent success rates compared to using Dice 4 then Dice 6.

If you want, I can:

  1. Give a step-by-step checklist for upgrading a specific item (weapon, armor, or jewelry).
  2. Look up the exact NPC name and coordinates for your game region/server (if you tell me which server or region you play on).
