Attack Interval

This page was last updated for (v1.2).

Attack Speed is determined primarily by the default Attack Interval on weapons and affects how long it takes between attacks. It is given as seconds per attack, so a lower number is better. A variety of things, such as Equipment, Pets, Spells, and Prayers can provide a reduction to the player's attack interval.

The base attack interval for all weapons can be seen on the Equipment page.

Attack Interval Reduction

In addition to the sources listed in the table below, the following things can reduce the player's attack interval:

• Using the Rapid attack style while using any Ranged weapon.
• Surge I, Surge II, Surge III, and Surge IV Spells
• Knight's Defender - Melee only. Reduces the player's attack interval by 0.1s
• Ring of Barrage - Ranged only. Reduces the player's attack interval by 0.15s for each successful hit in a row, stacking up to 5 times
• Gauntlets of Rage - Reduces the player's attack interval by 2% each time they are hit, stacking up to 10 times, which resets between monster kills
• Royal Toxins Spear - While the monster is afflicted by both Bleed and Poison, reduces the player's attack interval by 40%
• Frostspark Boots, FrostSpark 1H Sword, and FrostSpark Amulet synergy - When the player has each of these items equipped at the same time, reduces their attack interval by 0.2s
