Invictus means "undefeated" in latin, and that might very well refer to the challenge of making this disc turn.
Invictus is a disc that is designed to resist both head winds and big arms, and it can very well be described as a faster Firebird.
It is a disc that will fade, even in the headwind.
The Invictus probably shouldn't be the first disc you pick up as a new player, but when the form and the power starts to be in place, you will love the reliability of it in both forhand and backhand throws.
