Idle Upgrades are used to improve your output damage from your Auto Attacks. These upgrades can be bought with Gold or AP. Auto Speed yields the best Gold/AP in the upgrade menu.
Contrary to the description, this upgrade does not actually increase your auto attack rate by +x%. Rather, it reduces the delay between auto attacks (from the base value of 2 seconds) by x%. E.g. tier 3, +8% speed, reduces the attack delay to 92% of base. This reduction stacks additively with that provided by the ascension point speed upgrade.
The maximum level of Auto Speed is 200. Auto attack speed caps at a minimum of 500ms, and any speed beyond this is converted into damage.
Gold cost of Auto Speed is given by the formula
Level
Cost to Upgrade (Gold)
Cost to Upgrade (AP)
Effect (% Speed)
