The Sorceress is the final boss of Spyro: Year of the Dragon. She is not a very challenging opponent, however, the controls and the mechanics of the fight may cause some issues.
During the fight, you will have to use siege machines that Agent 9 will summon for you. After they drop to the ground, something in the shape of a shadow will appear. Only when you perform a jump will the weapon materialize. The first of them is a standard cannon. In this case, you will only have to adjust the elevation.
The second siege engine is a tank. It moves very slowly, which will make it difficult to dodge incoming attacks. Therefore, it will often be destroyed by the ranged attacks of the Sorceress. Unfortunately, in most cases, you will not be able to avoid this.
The last machine that you will have the opportunity to use will be a flying saucer. It has the ability to fly. You must be extremely careful with it. It reacts quite violently to altitude adjustments. This also means that it moves forwards and backwards very quickly, however, when it comes to turning, it is nowhere near as nimble. Although the Sorceress will not be able to hit it, it is very easy to accidentally fly into the lava and suffer damage from burning.
