Esoteric Warp Resonator

As each of the thirteen dials on this sealed orb are
rotated, the stored warp energy inside causes it to
quiver and glow.
At the start of each battle round you receive 1
extra warpstone spark if the bearer is on the
battlefield. That warpstone spark can only be
used to perform a warpstone spark ability with
the bearer in that battle round. If it is not used
before the end of the battle round on which it
was received, it is lost.
