Attack value is different than number of attacks. Attack value of a weapon increases the to-hit chance. Number of attacks is a separate stat, and e.g. Sword of Quickness has that ability.

You can see all the commander's weapons, and their respective attack values, by right-clicking on his attack (Att) value. Weapons with multiple attacks are listed only once in there, but all the unit's weapons are listed. So some of the Foul Spawns could have four tentacle attacks listed, while another might have two Claws attacks both attacking twice.

Besides that, Quickness always gives you whole round. So if you had four weapons (i.e. you are a Nataraja), you'd have 8 attacks instead of 5, twice with every weapon.
