Effect: - Converts certain objects or creatures into birds in a burst of electric blue light. This is actually an inanimate/animate to animate  transformation, that is a transfiguration spell, but I told you you could think out of the box for duelling.

Spell Type: - Offensive or Defensive(think defense against magical creatures).

Spell Block: -

Incantation- Avifors, pronounced as AH-vih-fors.

Wand Movement- Sidewise figure eight.

Willpower- Medium to High.

Concentration- Medium, focus on the image of the bird, how it should move and what you want it to do for you.

Please note that this spell has an interesting variation, Ducklifors, which turns the target into a duck. The spell type is same. The incantation is Ducklifors, pronounced as DUCK-leh-fors, the wand movement is a downward slash, the willpower required is high, the concentration required is high, focus on both the physical and mental changes that need to occur.

Please note that yet another interesting variation of this spell is Pullus, which turns the target into a chicken. The incantation is Pullus pronounced as PULL- us and the wand movement is to point wand at target. The remaining spell components are the same. A similar spell Vermiculus with the incantation Vermiculus pronounced as Vur-MICK-yoo-luhs and the remaining spell components being the same  turns the target into a worm.

Please note that this spell is not to be confused with Avis, the Bird-Conjuring Charm.
