Shield Maid

Introduction

Shield Maid is a tracker for the two Warrior abilities Ignore Pain and Shield Block. The addon helps visualize at a glance the amount of damage absorption ignore pain will gain when activated and estimate how effective shield block will be based on recent damage taken. The addon adds an icon for each of the two abilities. These icons change in saturation depending on rage available to cast each ability and, when active, show remaining duration for the buffs. The Ignore Pain icon additionally shows remaining absorb value while the Shield Block icon shows total damage blocked for the duration of the buff. The ignore pain icon can be configured to continue showing the estimated absorb value to be gained by repeated activations of ignore pain (enabled by default)

Mitigation estimates

The addon calculates the estimated value of Ignore Pain by looking at the DPS provided by your weapon, potential talent modifiers, as well as your Strength, Mastery, and Versatility levels. While at lower levels or participating in timewalking with lower values of ignore pain (<1million), it will instead parse the ignore pain tooltip for an accurate absorption amount, capped at a maximum value of 30% max health. 

The addon also keeps track of incoming, blockable, damage and uses this information to estimate how much your Shield Block ability will mitigate if activated.

Learning which spells are blockable

There is no exact way to determine wether or not an incoming attack is blockable before you actually block it. The addon remembers each spell you block and uses the information in future predictions. This approach also means that the addon will not interpret a spell as being unblockable until you have blocked it once.
