Towers of Certain Doom

$G Sir : Ma'am;, as we move through Skorn, we have to bring down those towers!$B$BIf you have a look at them, you'll notice that their tops are lined with casters. Getting too close to them would mean certain doom for us!$B$BHowever, we do have it within our means to call in cannon volleys from Westguard Keep. To do so, we need to get close enough so that you can lob a smoke flare atop of them.$B$BJust don't get too close!
