Hi,
just a little question :
when is the right timing to use Spear card ?
must I use it BEFORE the use of the ablility i want to reduce CD, or can i use it even if the ability has just been used to apply its effect ?
Is the cooldown reduction dependant on the "when" the ability is used or can i throw it whenever i want ?
For instance, if i want to help my fellow MCH, must i throw it before he uses wildfire (to reduce its cooldown once triggered), or can I throw it after he uses wildfire, and apply CD reduction afterwards ?

I am not sure to be quite clear... sorry (i'm french )
thanks for your answers, anyway ;-)
