• Inscription is the main skill; it gates both rune crafting and rune application.
• Magery 120.0 base is required to use the Rune Chisel. Without it, the gump reports “You don't have the required skill.”
• A Rune Chisel must be on the crafter's person. It wears down with use like any standard crafting tool.
• NPC scribes sell the Rune Chisel for 18,200 gp, stock of 20.

The crafting menu is the standard Inscription gump.

A stackable item (weight 1.0). One Rough Stone is consumed per Blank Rune. Players also receive one Rough Stone every 4 hours from the Obelisk of the Rune Crafter (240-minute interval, 100 charges).

Crafted from a Rough Stone in the Rune Crafting gump. Non-stackable (weight 0.0, hue 998). Recipe: 45.0 - 80.0 Inscription, 1 Rough Stone per Blank Rune.

Every enchanting rune recipe consumes 1 Blank Rune plus a quantity of Magery reagent(s). The full list:

Double-click a crafted rune in your backpack, then target the item you want to enhance. The rune and target item must both be in your pack (or on the ground within range 1); the target cannot be currently equipped. The system checks Inscription, rolls the break formula below, and on success applies the property and consumes the rune. On failure the targeted item is destroyed along with the rune.

Every rune requires 70.0 base Inscription on double-click. Below that, the rune reports “You are not skilled enough to attempt this enhancement.”

A skill check is then rolled between 70.0 and 110.0 Inscription. On failure the rune shatters and is consumed with the message “The rune shatters, releasing the magic energy.” The targeted item is not affected by this stage.

Once the skill check passes and a target is selected, the application roll works as follows:

1. Roll a base destroy chance in [0.0, 1.0).
2. If your Inscription is 105.0 or higher, add Inscription * 0.001 (e.g. 120 Inscription adds 0.120).
3. If the Better Rune Crafting perk is active, add 0.1.
4. Success requires the destroy chance to be greater than 0.40 AND a second independent roll greater than 0.02 (a flat 2% catastrophic floor that breaks the item regardless of skill).
5. If the Next Rune Crafting Application Won't Break Item perk flag is set, success is forced and the flag is consumed. The game reports: “Your perk gives your gear total protection during application, and expires.”

On success: the property is added to the item, a success sound plays, and the rune is consumed.
On failure: the targeted item is destroyed, the rune is consumed, and a failure sound plays.

Each rune checks targets in order: weapon (or ranged weapon for bala and vel), then optionally armor, shield, clothing, quiver, spellbook, or jewelry, according to the “Valid Targets” column above. A target that doesn't match any allowed type yields “You cannot enhance that.” and the rune is not consumed.

The Bag of Runes is a blessed container holding one of each rune type (excluding bala and vel). It is a staff/admin convenience item, not a standard player drop.
