The wand of pyrotechnics is a typical magic merchandise in Dragon of Icespire Peak. The textual content reads as observe:

This wand has 7 costs. Whereas holding it, you need to use an motion to expend 1 of its costs and create a innocent burst of multicolored gentle at a degree you may see as much as 60 ft away. The burst of sunshine is accompanied by a crackling noise that may be heard as much as 300 ft away. The sunshine is as shiny as a torch flame however lasts solely a second.

The wand regains 1d6 + 1 expended costs every day at daybreak. Should you expend the wand’s final cost, roll a d20. On a 1, the wand erupts in a innocent pyrotechnic show and is destroyed.

If an individual underneath the consequences of an invisibility spell makes use of the wand, would it not trigger the invisibility spell to finish?
My assumption isn’t any as a result of it does not rely as a spell or an assault.

My follow-up questions is that this:
Can an invisible individual use different magic wands or objects with out ending the invisibility spell, as long as the merchandise doesn’t say it counts as casting spell or the merchandise is not used to make an assault?
