Items granting spells

[NunoM]

When you have an item that grants the use of spells, like...

GOGGLES OF THE GOLDEN SUN
[...]
In addition, three times per day you can activate these goggles and sacrifice a prepared spell or spell slot of 3rd level or higher to use fireball (as the spell; Reflex DC 14 half), using your own caster level or that of the goggles, whichever is higher.

... can you use it to activate another item, like...

BRACERS OF THE ENTANGLING BLAST
[...]
When you activate these bracers, the next spell you cast or spell-like ability you use deals only half its normal damage; however, any creature damaged by the spell becomes entangled for 1d3 rounds,
[...]

...?

As long as activating both items is possible action-wise (no more than one requires a swift or standard or the like), yes.  You are casting that Fireball, for instance, not the Goggles.

Yeah, i forgot to mention that... The goggles are activated as "standard (mental)" (i assume it takes over the time of casting the spell it grants) and the bracers are activated as a swift action. So it's ok...

To better clarify this, the sequence would be: activate bracers and activate the goggles to cast fireball, entangling all caught in the fireball's area.

Thanks for the input!
