Call To Arms became famous in Diablo 2 Resurrected for its powerful Battle Order and Battle Order skill bonuses. It's a runeword, abbreviated "CTA", and works great for non-Barbarian characters. But making this runeword is difficult, not only requires a 5-socket weapon, but also collects five runes, and you can't get it before Hell difficulty.

Diablo 2 Resurrected Items craft a 5-socket weapon from Normal or Larzuk in Nightmare, but the weapon must be dropped on Hell difficulty so that Larzuk can add up to 5 sockets to it.
The Call To Arms runeword is made up of an Amn rune, a Ral rune, a Mal rune, an Ist rune, and an Ohm rune, and you need to put them in the weapons in exactly the order stated. You can farm the first four runes in The Countess in the Forgotten Tower, for example you can farm Ral in Normal and above, Amn in Nightmare and above, and Mal and Ist in Hell.
