Immobulus to stop him in his tracks!
Stupefy to stun him!
Exspelliarmus to disarm him!
That was wrong of me to chose Stupefy/Exspelliarmus. Time to strike with a Confundo!
I'm going for Depulso!
With him immobilized right there, time to step back and hit him with Confringo!
I have him confused, no worries here! "What am I doing here?" says Fenrir Greyback!
Better safe than sorry! I had better put on a Shield Charm to ward the Exspellliarmus blast away!
Depulso had no luck, time for Petrificus Totalus!
He's Body-Bound and I have to recover my wand, the snake never came for me!
He's confused so I have no worries until it wears off!
The Counter-Spell is Arania Exumai!
The Counter-Spell is Vipera Evanesca!
AHHHH THE SNAKE IS BITING MY HEAD!!
That stupid serpent is still there, so I'm going to use a Knockback Jinx on it and quickly attack Fenrir Greyback by using Sectumsempra on him!
"Time to die, serpent!" I shove my wand through his mouth!
Confringo? I can hide behind this barrel!
Confringo, huh? I could use Agua Eructo to put out the blast in midair! Then I could shoot him down with a rapid blast of Stupefy!
WOOHOO! GREYBACK IS SEVERELY STUNNED FROM MY BLAST OF STUPEFY! HHOORRAAYY!!
OH MY GOSH!! MY WAND!! MY ARM!! NOOOOOOOOOOOO!!!!!!!!!!!!!
HA! TAKE THAT SNAKE! KNOCKED RIGHT BACK! HA! OH, AND GREYBACK! YOU ARE CUT UP! HAHAHAHAHA! EAT INVISIBLE SWORD!
