wasted a couple of flame rounds and a flash grenade before activating it.
I've tried that a bunch of times, it always seems to get hold of me...Not that you need to kill it anyways as you can just walk past it without it attacking you.
If we're talking about the licker in the STARS hallway, walk into the office, don't run. When you leave and go down the hall toward the Unicorn Medallion room, walk but swing out so that when he comes around the corner on the side of the wall he doesn't touch you, signaling him to your presence. You should be able to make it to the room at the end of the hall without an attack.I've tried that a bunch of times, it always seems to get hold of me...
