It seems not working. It should return ms but so if i check:

if (ObjectManager.Me.BuffTimeLeft("Thorns") <= 10000)
{
	Thorns.Lounch();
}
                                                    

it always true and it rebuff thorns nonstop. Same for:
ObjectManager.Me.BuffTimeLeft(new List<uint> { 9910 }) <= 1000
and same for:
ObjectManager.Me.BuffTimeLeft(new List<uint> { 9910 }) <= 1
 

this code also always return true

<QuestsSorted Action="While" NameClass="ObjectManager.GetObjectWoWUnit().Where(u =&gt; u.IsDead &amp;&amp; u.IsLootable &amp;&amp; u.GetDistance2D &lt;= 40) != null" />

Hello, can you share result of "Player/Target Buff/Debuff" (you can found this button in "dev... tools" (tab "tools")) (when you have this buff)

Sure.

Seems like It always returns "TimeLeft" == 0, for all buffs. Have not noticed this at first time

 

Ah, i see, sorry for disturbance then.
