The Monster attack speed of a monster determines the rate of which a monster can attack. This is a factor which balances the attacking power of a monster.

The speeds of monsters are represented by a bar on which there are several possible values ranging from 9 (fastest) to 1 (slowest). The bar is separated into ten squares of lightening shades of blue. The value represents the number of squares shown, with 10 displaying a full bar and 0 displaying an empty bar. The delay time in seconds between each attack is equal to 6 - 0.6*(Speed Value). The 0.6 seconds is the basic unit of time that RuneScape runs on; all monster attack speeds are an integer multiple of this tick time.
