Mask of Madness

The Mask of Madness is an Item purchasable at the Main Shop, under Artifacts.

Tips

 * Mask of Madness is the most cost-effective Attack Speed item in the game, costing only 18 gold per point of Attack speed.
 * Works well with Bash effects. The movement speed allows you to chase and the bash prevents your prey from hitting you back effectively.
 * Some heroes with very high right-click damage output such as Sven and Tiny can easily offset the 25% damage vulnerability with the 20% lifesteal.
 * The 25% damage vulnerability works reasonably well with Blademail; yes you take 25% more damage, but you also thereby reflect 25% more damage than normal.
 * The active is extremely useful while farming. Taking 25% more damage is negligible when simply running between lanes or hitting lane or jungle creeps.
 * The MoM user should always be wary of heroes with high burst such as Nyx Assassin or Lina that can really punish the 25% damage vulnerability, especially if the enemy has vision while the active is on.
 * Purging off the Berserk buff also removes the +25% damage vulnerability, and not just the attack speed and movement speed bonuses.
 * One of the best ways to counter a MoM user in a fight is to focus them down with nukes and disables while they are taking the 25% bonus damage.
 * It is possible to work around this vulnerability by buying to avoid being nuked or disabled by spells, items, etc.
