Other than the similar caster trinket 『喚日者』貝羅洛斯, this one cannot be used, unless you are in range.
In your action bar, the trinket gets a red point in the upper right-hand corner indicating that you're out of range.
The max range seems to be 6y (measured with the addon RangeDisplay).
It doesn't trigger a GCD, so you can macro it to just anything, run in range while shooting stuff and back out. (This might not be the most professional way to use it. Thank you for pointing it out! I am aware ;) )
