The Saradomin sword is a two-handed sword which can be obtained in the God Wars Dungeon. The sword is a possible drop from Commander Zilyana and her bodyguards in the Saradomin area. It requires 70 Attack to wield. Its special attack, Saradomin's Lightning, adds 50-160 extra magic-based melee damage to the standard melee attack and raises the maximum inflicted damage by 10% for the melee hit. Players receive magic experience for using this special, but only for the magical hit. Essentially, the special deals two attacks: the melee attack that the player would normally have hit (with its maximum inflicted damage raised by 10% however) without the special, and an extra magical attack that can deal 50-160 (or 90-200 with ferocious ring) damage. The bonus from a hexcrest or full slayer helm on a slayer task is applied to this magical attack. The special attack drains 100% of the special attack bar. The Saradomin sword's overall stats are the 6th best for a two-handed sword, surpassed by all four godswords and the dragon 2h sword, although the Saradomin sword is notably faster than all of them.

Saradomin swords are very popular for training strength among players because they are faster than godswords, at a cost of strength, and hit as high as an abyssal whip. Even though the Saradomin sword and the abyssal whip have almost identical stats, the Saradomin sword can do a combined damage of up to 790 with the special attack while the Abyssal Whip with a Strength level of 99, an Overload/Extreme strength potion, the Turmoil prayer with a +32% strength bonus, a Slayer helmet on a Slayer task, a Ferocious ring worn inside Kuradal's dungeon, with Bandos armour and a fire cape can only do about 618 damage. However, the whip is one-handed and therefore players can benefit from the use of many types of shields, books, and defenders, as well, so the player needs to determine whether the extra damage is worth the reduced defensive capability. For the regular training grind, the answer is likely yes, because of the extra damage, but for other parts of the game, quests, boss-hunting, PvP, the answer might be different depending on your stats and other equipment.
