ATKT Siege Solo FC Gun(Slap)lance - Area 4

I'm not a Gunlance main in world so I used the most beginner friendly and super strong Slaplance build! I got a too excited during the 2nd topple since I knew I was close and my pacing was good that I pressed triangle too much and it did the wyrmstake lol. It worked out and I got a cool finisher from it!
