Effectively the opposite of an Amplify Shield, a Maylay Shield has no special effects as long as it is charged, but as long as it is depleted it will grant the user a set amount of bonus roid damage to all of their melee attacks. To utilize this, the user must keep taking damage to reset recharge delay, as well as using other means to regenerate health lost from the damage.
As rarity increases, roid damage as well as shield recharge delay increases. This is the only shield that has a potentially negative bonus with rarity.
Roid Damage also enhances the damage of Maya's Phaselock.
Three missions in the game offer a guaranteed Maylay shield reward.
