Target unit becomes radioactive for 30 seconds. All air and ground units within 2 matrices of
affected unit receive up to 250 hit points of damage including the affected unit itself. You can target
any unit but only organic units will receive damage.
You cannot use Irradiate on buildings.
Activating multiple Irradiates on the same unit causes no additional damage. But overlapping
Irradiations will cause more damage to a particular unit if they are near enough to each other.
This ability is particularly effective against grouped ground troops such as Terran Infantry units,
all Zerg units, Zealots and more.
Irradiate is primarily an anti-Zerg weapon but it can work on collections of Marines, Firebats and Zealots.
Use it on tightly packs of Mutalisks and Guardians especially. Players will have an incredibly difficult
time separating the Irradiated unit from the other units before the damage has been done. Irradiate can quickly
make short work of groups of Guardians and Mutalisks in tight packs.
Use Irradiate on units not affected by it such as Siege Tanks, Dropships, Goliaths, then run them
into the enemy. If the enemy uses Melee units like Zealots, Zerglings, and so on to attack the Irradiated
unit they will be damaged when they try to attack that unit. Use Irradiate on a Siege Tank. This
will get Zerglings that are attacking the Siege Tank. This won't cause the enemy significant damage, and
may not even allow the Tank to survive, but it will damage the enemy units somewhat. It's kind of funny
too. You can also just use Irradiate on their units instead of yours. But is that as funny?
Irradiate also does wonders on Ultralisks. It will cause a little over 200 hit points of damage
to the Ultralisk. Use Irradiate on Zerg Overlords to put the Zerg behind in Supply.
Defensive Matrix does not prevent Irradiate but it can slow the process down.
Try using both Irradiate and Defensive Matrix on an Overlord. It looks pretty neat.
Irradiating a Dropship causes no damage to the Dropship or the units inside.
If you Irradiate Terran Infantry units, and place them in a Dropship, that unit will die
and other Infantry units in the Dropship will also receive damage. The same is the
case with Bunkers.
Use The Medic's Restoration ability to remove Irradiate.
The Following units are affected by Irradiate:
Terrans: SCV and Barracks troops (Marine, Firebat, Ghost, Medic)
Protoss: Zealot, Dark Templar, and High Templar
Zerg: All Zerg units.
An interesting strategy is to use Irradiate on units immune to it while moving them near enemy
units to damage them. Try this with flyers then fly over enemy units and mining operations.
Although this may not be very effective it's certainly original and unexpected.
