Call to Arms Runeword: Stats, Best Bases & Builds
Call to Arms is the swap weapon every endgame character carries. This guide covers its stats, rune formula, best bases, and what different rolls trade for.
Call to Arms Runeword: The Swap Weapon That Defines Endgame
Call to Arms is not a main-hand weapon — it is a swap weapon that every single endgame character carries in their inventory, switches to when fighting a boss, hits once or twice to trigger Battle Orders, then swaps back to their real weapons. The runeword's stat package is so efficient that skipping it leaves damage, life, and attack speed on the table. This guide breaks down the runes, bases, and returns at every budget tier.
Rune requirements and stat breakdown
Formula: Amn + Ral + Mal + Ist + Ohm (5 sockets, only weapons, all bases).
This is the first 5-rune word most endgame characters assemble. The payoff is immense:
- +2-6 to Battle Command, +1-6 to Battle Orders, +1-4 to Battle Cry — all three Barbarian shouts, usable by any class through the item, with Battle Orders' life/mana buff being the reason everyone carries it.
- +1 to all skills — a flat +1 to every build skill stack.
- +40% increased attack speed and +250-290% enhanced damage — the swing itself hits hard enough to actually proc Battle Orders in one or two hits.
- 7% life stolen per hit and Replenish Life +12 — helps melee survivability during the swap.
- Prevent Monster Heal and 30% Better Chance of Getting Magic Items — minor but free utility riding along on the swap weapon.
The reason Call to Arms defines the economy: every class wants one for swap. A Sorceress swaps to Call to Arms, hits, Battle Orders stacks, then swaps back to Infinity staff. A Smiter juggles Call to Arms and Grief every other swing. A Summoner Necro uses Call to Arms + Concentration aura on a merc, then swaps back to Beast for summon skill levels.
Best bases for Call to Arms
Ideals: Phase Blades and Great Polearms have the lowest rune requirements (5 sockets easy to guarantee via Larzuk), fastest swings, and solid base damage. Phase Blade is the meta swap: 0 base damage means the runeword damage is pure, and attack speed cap aligns perfectly with Call to Arms' IAS.
Budget: Cryptic Axes and Winged Helmets (yes, as a 1H weapon) are 5-socket drops early ladder and carry the runeword just as well. They look different, cost slightly less in trade, and perform identically.
Ethereal: Ethereal bases add 25% damage and zero repair cost (if you Zod-socket them later). Eth Phase Blade is the rarest early-ladder find but the ideal endgame swap. Eth Great Polearm is a mercenary Call to Arms if you have a character with spare 5 runes and want a summon merc with maxed Battle Orders.
Socketing: Never use Larzuk on a weapon for Call to Arms — the quest always guarantees the minimum. Farm Hell Countess, Hell Andariel, or LK for natural 5-socket bases and save Larzuk for shields and armor where it matters more.
Variable rolls and what to look for
Call to Arms rolls variable shout levels — Battle Command, Battle Orders and Battle Cry each land somewhere in their range (2-6, 1-6 and 1-4 respectively). A copy that rolls high Battle Orders is marginally better since that skill level drives the life/mana/stamina buff, but the difference between a low roll and a high roll is small change in trade value — maybe 1/10 of a high rune. For most ladder phases, any Call to Arms is "good enough" until loot luck throws you a max-roll copy.
Enhanced damage also rolls in a 250-290% range, but it barely matters for a swap weapon you hit with once or twice per fight.
Who uses Call to Arms and why
Every. Single. Class. Sorceress swaps for Battle Orders duration and skill boost. Paladins swap mid-fight to refresh auras and Blessed Hammer levels. Barbs swap for the IAS + damage before WW. Necros swap to boost summon levels. Amazons swap for missile skill boost. Druids swap for elemental or melee skill prep. Assassins swap for martial arts or trap boost. The swap is so efficient it is literally free DPS.
Build one Call to Arms by day four of ladder. Use it to farm bosses and high-density zones faster. Watch your clear times drop by 20-30%.
Budget alternatives and upgrade paths
Early ladder (pre-high runes): Stealth armor, Lore helm, Insight merc staff, and one Spirit sword carry you to Nightmare endgame. Call to Arms rune cost is modest (Amn is farmable in minutes) so build it by Hell Countess if possible. There is no cheaper alternative — you do not skip this one.
Mid-ladder: Once you have Call to Arms, you have the flexibility to farm bosses and high-level zones with less gear pressure. Pair it with Grief on a melee, or stack it on a merc polearm (merc Call to Arms grants your whole party Concentration aura if the merc has the skill).
Endgame: You own 2-4 Call to Arms by endgame. One on each class's swap weapon, maybe one on a merc if Concentration + Battle Orders stacking matters. Store them in your stash for easy access across characters.
Cost and trade value
Amn, Ral, Mal, Ist, and Ohm are mid-to-high runed gems. Ist rune is the price gate (worth ~1 High Rune or ~5 Lem). Total Call to Arms cost is roughly 1.5-2.5 high runes depending on ladder phase. By week two, high-rune farming makes this budget trivial. Do not delay the build waiting for perfect shout rolls — a low-roll Call to Arms farms just as well as a max-roll one, and you will replace it for better bases later anyway.
Eth Phase Blade Call to Arms trades for premium in-season but older seasons see the bases drop 50% as ladder maturity accelerates rune availability. Grab a phase blade natural drop, socket it via Larzuk if you trust that quest, and move on.
