Why do GoS sigils count against me for spellburst in the Sanctum? It was only after I added them that I popped. See below:

sigil of mending
Your heart begins to beat faster as your entire body becomes awash with a pleasantly warm sensation.
>
sigil of contact
You concentrate on your sigil.
>
sigil of resolve
You experience a momentary flash of insight on how to best overcome nature's obstacles.
>
sigil of defense
>
You suddenly feel the essence surrounding you shift and writhe chaotically!
A dark shadow seems to detach itself from your body, swiftly dissipating into the air.
Some eahnor-washed mail riveted to thick layers of raw silk padding partially deflects the onslaught of the shocking attack.
... 14 points of damage!
Heavy shock sends you to the ground with convulsions!
You are knocked to the ground!
You are stunned for 7 rounds!
You suddenly feel the essence surrounding you shift and writhe chaotically!
You feel your extra magical awareness leave you.
... 3 points of damage!
Chilly blast to the left eye leaves you in tears.
You suddenly feel the essence surrounding you shift and writhe chaotically!
The silvery luminescence fades from around you.
... 12 points of damage!
Good blow to your head leaves you confused!
>
You are still stunned.
>
The moment of enlightenment and magical comprehension fades from your mind.

You inhale deeply upon your pipe, puckering your lips as you send out three rings of smoke before you, then puff out a small vine of smoke that darts right through all three which causes them to disperse in a hazy shroud!

The burst on a pulse is exactly how it happens in SoS as well.

It's not like, say, the Rift, where spells are stripped upon entry.

For the most part very high AS is not a huge worry in SoS. Untik you get your skills up enough maybe not get elemental 1 and 2 so you can wear the four combat sigils
