Ornn's Forge Menu is a special menu in the HUD which has 5 slots. The player can quickly forge one of the recommended items by clicking on its portrait or via the Champion Specific Interaction hotkeys (default: Shift+F1–F5).
The item that Ornn upgrades for the ally is decided at the start of the forge channel.
If the ally moves the item into a different slot during the channel, it will still be the item that gets upgraded.
Masterwork items inherit all properties of their pre-upgrade version, including the cooldowns of their effects. Internally, they are handled through an item modifier. An upgraded item gains the (Masterwork) descriptor next to its name in tooltips as well as a special Masterwork frame overlay on the item's icon itself, both indicating the application of Living Forge's modifier.
Statistics' gold value and eligible stats to be increased for Masterwork items:
31.25 gold per 1 point of ability haste.
20 gold per 1 point of ability power.
35 gold per 1 point of attack damage.
30 gold per 1% of attack speed.
20 gold per 1 point of armor.
18 gold per 1 point of magic resistance.
1 point of health has a variable gold value gold, based on the number of upgradeable stats that exist on the item:
If health is the item's only upgradeable stat, it receives +375 health and health is valued at 2.{{recurring|6}} gold per point.
If the item has health and only one other upgradeable stat, it receives +185 health and health is valued at 2.{{recurring|702}} gold per point.
If the item has health and two other upgradeable stats, it receives +125 health and health is valued at 2.{{recurring|6}} gold per point.
If the item has health and three other upgradeable stats, it receives +90 health and health is valued at 2.{{recurring|7}} gold per point.
While not currently possible, if an item has no upgradeable stats, 1000 gold worth of health (valued at 2.{{recurring|6}} gold per point) is added to the item.
The Masterwork stat increases are rounded down (any decimal values are lost).
Living Forge's bonus armor and magic resist increase stacks additively with Voidborn Resilience and multiplicatively with Mountainous Vigor.
Health and mana items built on the field will retain Ornn's previous health and mana percentage. Returning to base still brings health and mana back to full.
Ornn's basic attacks against Brittle enemies will end the duration of the debuff on-hit prematurely even if the knock back was not applied. This does not trigger the consumed effect that deals the bonus damage, unless the target was an epic monster.
Brittle's Tenacity reduction will benefit all applicable types of crowd control, not just immobilizes and silences. The following do not consume Brittle but benefit from the reduction: blinds, cripples, disarms, grounds, and slows.
Spell shield will block both the knock back and the bonus damage from Ornn's empowered brittle attack.
The bonus magic damage inflicted by Brittle is credited to Ornn, and benefits from his magic penetration.
The Masterwork item upgrade on an ally will fail if the ally was channeling the Rift Herald Rodeo at the time of the forge's completion.
The following table refers for interactions while Ornn is channeling:
All of Ornn's actions are disabled during the first 0.5 seconds of the channel.
