Guild Wars 2

On the TA up path, at the spiders before malrona. I noticed my skills were recharging faster, an effect like alacrity (seconds left were shown green instead of white). I checked the boons bar and i had a boon called Queen’s Frenzy (Skills attack faster and recharge faster). It wasnt a boon really it was like the boons Captain Ashym gets in ascalon fractal. Anyone know how this effect is applied ?

When you reflect the projectiles from one of the spiders, you get this buff.

Good to know, was on mesmer, so that makes sense.
