[dariuzsdk]

1. Current Behavior

Anti Magic Shell https://www.wowhead.com/wotlk/spell=48707/anti-magic-shell is being reduced by Improved Concentration Aura https://www.wowhead.com/wotlk/spell=20256/
{Describe how that mechanic/spell/npc is currently working, in detail}

1.2. How to Reproduce

Step 1. Group up with a paladin with 3/3 Improved Conc aura https://www.wowhead.com/wotlk/spell=20256/
Step 2. Use AMS
Step 3. Notice AMS is only 5s or 3s duration depending on whether or not you have the glyph

1.3 Source Material

(https://clips.twitch.tv/DarkTolerantThymeTTours-m3udrOsASD-x3Q8X) 2 AMS in this clip, 1 without 1 with and the different durations.

2. Expected Behavior

AMS should not be affected by IMP conc aura as it is not an interrupt.

This was a bug back in the day: https://youtu.be/BYK6OkFwbv8?t=357

not only 5s, any bracket, just had ams multiple times for 5 seconds instead of 7 with the glyph.

Can confirm the glyph is just randomly not functioning in a variety of scenarios/brackets

In this clip; first AMS is 7 seconds, 45s later its 5 seconds
