Great when taking out creep waves, first burrow strike the ranged creep in the back of the group, this should stun all the enemy creeps and they should all be low heath then this passive should kill them all at once. Basically a safety spell, you can Burrowstrike out of the sand storm. Good for escaping spells and heros, good for pushing early game, good for spooking the other team.
When you use this spell, any thing that is in the path of your target gets stunned too, if you can get a good angle on the enemy team then you could technically stun them all. Once you get use this on enemy creep waves to stun them then just kill and get your easy earned money. Did I mention 11 sec cooldown? For early game use this to initiate lane fights. This move is your bread and butter, used to stun and deal damage.
