Attack Interval

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. Items, pets, or effects that affect attack interval is described below.

Objects that reduce your attack interval:

Elder Crown - Drop from Elder Vampire.
Sand Treaders - Drop from Turkul Riders.
Surge I / Surge II / Surge III - Spells.
Otto - Pet from Dark Waters.
Knight's Defender - Thieving from Knight, Melee only.
Ring of Barrage - Level 90 ring.

Objects that increase your attack interval:

Guardian Amulet and Spiked Shell Ring - Negatively impacts attack speed.
- Guardian Amulet - Drops from Earth Chests upgraded from Earth Shards, Earth God Dungeon.
- Spiked Shell Ring - Upgrade from 10 Guardian Rings and 500 Stinging Essence
Slow and Frostburn Debuffs

For Ranged, a common strategy is to use the best Throwing Knives available, using the Rapid attack style for another -0.4s attack interval.
