Rune Arm

Rune Arm concept art

Overview

Rune Arm (or Arm Cannon) is new kind of equipment implemented with Update 11 and the Artificer class. It goes into secondary weapon/off hand slot and requires Artificer Rune Arm Use feat (Artificer level 2 class feat) to use.

Rune Arms can be used in the offhand (with crossbow). The Rune arm has unique magical properties such as: Imbuing magical weapon damage to the main hand weapon attacks (and glancing blows with proficient Dwarven War Axe or Bastard Sword use), magical enhancements, and being modifiable via the Cannith Crafting system.

The Rune Arm also functions as a weapon as a free action (not restricting the users ability to cast or attack). The weapon uses Charges with five tiers, and these charges increase in damage the higher the tier (Rune Arms have a max tier level). Charges can be added standing still or while moving limited by the "Stable Charge Tier".

Rune Arms are currently only acquired by finishing certain quest chains, or in certain chests already known for dropping named and/or rare loot, such as the three dragon chests in Gianthold Tor; there are currently no randomly generated Rune Arms. The complete list of known Rune Arms, as well as their location, are below.

Interaction with other classes

• Rune arms uncenter Monks
• Rune arms break Druidic Oath

Crafting

Some Rune Arms can be enchanted further by applying Cannith crafted Shards. These Rune Arms will have the Craftable Rune Arm (+X) property which defines the maximum enchantment level it would permit.

On a Rune Arm crafting shards are applied as if it was a trinket, and adding crafting enchantments raises the minimum level requirement accordingly (2 levels per 1 enchantment level of shard applied; the minimum level will equal (the total enchantment level *2) -1). Currently the Minimum Level for crafted Rune Arms will not increase above 20, i.e. adding a +1 shard to ML 19 one makes it ML 20, not 21. The Bound Shard of Masterful Craftsmanship I works on Rune Arms to offset the Minimum Level increase and can actually lower the Minimum Level by 2 on a Rune Arm that has no other Shards applied.

The Disjunction Station in the crafting hall cannot reset a Rune Arm however, a Crafted Rune Arm can be reset in a Device Workstation using a Dust of Disjunction.

How it works

• Can be worn together with one-handed weapons and crossbows (not bows)
• Tapping the Alt button will start charging it up,
  tapping it again fires it. You can keymap a different button if you wish.
• You can Toggle the Rune Arm Use feat on while on an actionbar to make it keep autocharging.
• Damage will be affected by Artificer level and charge tier.
• Rune Arms will give a bonus elemental damage to the weapon in your main hand.
• Blocking with a charge reduces the charge to its maximum stable tier.

Quote: Originally Posted by Eladrin Each rune arm has a maximum tier - Thought Spike, for instance, can only charge up to Tier 2. That information will be added to their tooltips shortly.

Quote: Originally Posted by Eladrin Yes. (Technically it's the other way around - Max Tier sets the Imbue power. ) Rune arms are non-ki items. Spinning, loud, distracting, magical vortex generators damage my calm. They can only be used with one handed items (as well as crossbows).

Quote: Originally Posted by Eladrin The caster's spell damage amplification effects and enhancements modify the rune arm's damage. Metamagics do not affect any of the rune arm spells at this time. They use your Artificer level as their caster level and your Intelligence modifier - it's more or less as if you were casting a spell through the relic. The spells count as having a level equal to their charge tier plus one.

• This doesn't seem to match the in-game DC, see this thread.

Increasing Rune Arm damage

• Items and enhancements that increase spell damage or create spell criticals also affect rune arm damage.
• Runearms don't benefit from items with a bonus to caster level on Evocation (Infused Chaosrobe, Might of the Abishai).
• Runearms don't benefit from Prestige Bonuses to caster level (Radiant Servant will not boost Candlelight/Coronach/Tira's Splendor, for instance).
• Runearms do benefit from the Spellsinger's Song of Arcane Might.
• The DC of Rune Arm blasts is:

10 + (Charge Tier + 1) + (INT modifier) + (Max Charge Tier - 1) + (Evocation Feat Bonuses)

• Items that increase Evocation DC do not seem to modify Rune Arm DC.
• Different Rune Arms can be resisted with different saves (Fortitude/Reflex/Will).

Table of named Rune Arms

As of Update 14, a total of 25 named Rune Arms have been added to the game. They most commonly appear in the end-reward lists in most chains or quests (Sharn Syndicate being the exception, which doesn't seem to award one). They may also be found in some other named loot/raid chests. Additional rune arms are available from the DDO Store (ML5 and ML13 variants, e.g. Greater Force Rune Arm).
