This is my protection paladin weak aura set up. From top to bottom, it does as follows:
First row:
-Text appears when hammer of justice, blinding light, and rebuke are off cooldown.
-The circle above skill slot 7 appears when divine shield is off cooldown.
-When a defensive skill is used, its active duration appears above skill slot 7. If multiple defensives are used, the WA will prioritize showing the remaining duration on the first active defensive ability.
-When word of glory is free to use, three gold symbols appear above skill slot 5.
-When your health potion is off cooldown, a red texture appears above skill slot 8.
Second row:
-Shows key paladin abilities across eight skill slots.
-Consecration (Skill Slot 3) desaturates until you exit its area of effect or there is 2 seconds or less left on its duration.
-Skill slot 7 shows Sentinel when it is off cooldown. When Sentinel is on cooldown, the icon changes to Eye of Tyr. If both of those skills are on cooldown, the icon changes to Ardent Defender. If all three of those skills are on cooldown, the icon changes Guardian of Ancient kings. If all four skills are on cooldown, the icon changes back to Sentinel, desaturates, and fades out.
Third Row: Health Bar
Fourth Row:
-Shows remaining duration of Shield of the Righteous buff (blue)
-Shows remaining duration of Divine Shield (purple)
-Blue shield to the left of the bars shows when Blessing of Dusk is active.
-Red shield to the right of the bars shows when Blessing of Dawn is active.
Fifth Row:
-Holy power bar. The bar is red when the player has one or two holy power, green when the player has three or four, and purple when the player has five.
-Holy power bar also functions as the cast bar (blue).
Sixth Row:
-The lightning bolt shows when the trinket I am using is off cooldown. Change to your trinket.
-If you have a second on use trinket, you can duplicate the lightning bolt, change its color, and move it down some.
