The Zamorak godsword is one of the Godswords that was fought over during the God Wars. It is created by adding the Zamorak hilt to a completed Godsword blade.

Like all Godswords, it requires 75 attack to wield. It has a special attack called Ice Cleave, which freezes the opponent for 20 seconds, similar to Ice Barrage, and appears to boost accuracy. This drains the special attack bar by 60%, preventing consecutive uses. It is the only melee weapon that has a "Freeze" effect, making it useful for players who do not train Magic or do not have a high enough Magic level to cast any advanced ice spells. Also, it's less expensive over time than using Ancient Magicks.

This weapon is very popular in Castle Wars, mainly for its ability to freeze flag holders wearing Dragonhide armour or Armadyl armour (to decrease the accuracy of spells cast by Ancient Magicks users) because those armours are not very effective against the melee-based Godsword.

It is also a very popular method in the God Wars Dungeon when battling Commander Zilyana.

Of all the Godsword types, the Zamorak godsword is the rarest. Due to having the least demand, the Zamorak godsword is the second cheapest Godsword in the game after the Bandos godsword. The main reason why the Bandos godsword is cheaper than the Zamorak godsword is because there is a greater supply of Bandos hilts in the game.

Despite its reputation as being the "worst" Godsword, it has a few perks that are often overlooked. Most of these are helpful in PvP situations.

Its special attack can freeze a mage in place to prevent farcasting, leaving the mage defenseless (effective on PvP).
Like all "freeze" effects, the special attack interrupts combat, forcing the victim to click "Attack" to resume fighting. This often gives the wielder a moment to inflict damage without being attacked back if the victim is not aware of this effect. (only effective on PvP)
One tactic that a Zamorak godsword wielder can use is to stand under the opponent after using the special attack. This prevents counter-attacks. The wielder can step back out to attack and then retreat back under the opponent. While the wielder can still be hit back, even fast weapons like whips will not get any more hits than the Godsword user, temporarily removing the disadvantage of the weapons's slow speed and making it in a sense the "fastest" Godsword for the duration of the special attack.
Unlike the other Godswords, the Zamorak version always has an effective attack if it hits. If it hits a 10 (or sometimes even a 0) the freeze effect has its full duration, while the other versions would have nearly no effect at all.
It's very handy for using at the Barrows minigame. Players will use the freezing special on Verac like people do with Barrage, then pelt him with slayer dart or use Black Salamanders. It's also handy for freezing any tunnel monster in the penultimate room to the chest room as the special attack will freeze the monster in place allowing one to complete the puzzle required for the chest room.

Unique to the Zamorak Godsword is that while the other Godswords have a dark tint near the hilt and the tip of the sword, the Zamorak Godsword lacks this tint, being a full bright silver colour from base to tip.
