Decaaut
Main Article: Actions
One decaAut (deca-aut, sometimes referred as a turn) is equal to 10 aut, or 10 arbitrary units of time. It is the time it takes for an untransformed, unstatused human to wait (with s or .) for one turn. It is also just the 'standard' time for an action, and thus useful as a general measurement (such as turns until the Zot clock runs out).
Most species and monsters take 1 decaAut to move, and it is the time it takes for all species in their natural form and condition to do many actions (like reading scrolls, quaffing potions, or casting spells). A primary exception is attack speed, which is often measured by delay; weapons can take from 0.7 to 3 decaAut to swing, before modifiers like shields and skill.
