The Wizard essentially has a single ability, but it is extremely versatile. He or she can project his memories of past lives into the minds of others, essentially making them think they are being attacked by strange creatures. These imagined creatures have very real effects on those who are imagining them.
Knee is the one skill the Wizard can use that physically does anything. It is just a basic melee attack. All of the Wizard's other skills either grant him a new form, or give him new abilities to use in that form. The Wizard does not really change into these forms, but just makes enemies think he is, very convincingly.
Mind Projection is the prerequisite for all of the Wizard's forms. He or she cannot have more forms than ranks in Mind Projection, and the maximum number of ranks in Mind Projection is three. Therefore, the Wizard can only ever have access to three of the six forms.
The first of these forms is called a Tik-Chat'chtka. It is a large, red, fly-like insect that lives inside of an asteroid. Their entire lives take about thirty seconds, so they reproduce very quickly. It is capable of flight and hovering, and has the best aerial maneuverability of any playable character. The Tik-Chat'chtka's skills include Sting, which allows it to charge into enemies and damage them, and Latch On, which lets it grab onto an enemy and continuously do damage until it gets knocked off. While Latched On, it can use Lay Eggs and Rake. Rake does an extra burst of damage on top of the continuous damage of Latch On. Lay Eggs allows the Tik-Chat'chtka to lay eggs inside of an enemy. The Tik-Chat'chtka operates on a 30-second timer. When this timer expires, the player dies, unless there are eggs laid inside an enemy. This causes a new Tik-Chat'chtka to hatch, replacing the old one and doing damage to the host. When the new animal is born, if the Wizard took damage as the Tik-Chat'chtka without switching to another form, some or all of that damage will be healed.
Another form is the Crizzle, an armoured slug-like creature with a lance. It originates from a lush, forested world where they have reached medieval-level technology (or had when the Wizard was one of them). Its two attacking skills are Lance, which can only be used while moving and has quite a long range, and Execute, which does extra damage and can only be used when the enemy is at low health. It also has Battle Horn, which briefly increases the damage done by its attacks, and Squishy, a passive ability that gives the Crizzle a chance to take less damage from attacks.
The Thorb is the Wizard's next form. It is a massive organism the size of a small planet. There are many other species living inside the Thorb, including the Narwalrus, which (not surprisingly) is like a Narwhal combined with a Walrus. When the Wizard takes on the form of the Thorb, he or she surrounds the enemies, which end up inside the Thorb. The player then takes control of a resident Narwalrus. This Narwalrus has one attack, called Incapacitate, a melee attack that does a small amount of damage and stuns the target. The rest of the attacks in this form come directly from the Thorb, and affect all enemies on the screen (barring certain circumstances, like enemies that are immune to damage for some reason). These attacks are Stomach Acid, Deadly Moss, and Bodily Purge. Stomach Acid coats all enemies in a strong acid, doing damage to them over a long period of time. Deadly Moss appears underneath every enemy when used, and slows anything that tries to move through it down substantially. Bodily Purge does a fairly large amount of damage to all enemies, and throws them all around in random directions.
Next is the Riordan form, which is a small, boney, almost rodent-like humanoid. It has a very large head and empty-looking eyes, giving it a nearly skeletal appearance. Its most commonly-used ability is Deadly Aura. This creates a dark circle around the Riordan, protecting it and damaging enemies. Any enemy that comes in contact with the Aura takes damage and is knocked back. It only lasts for a short time, however, and it will break under sustained pressure. It both destroys and is destroyed by projectiles. Bone Density is a passive ability that increases the Riordan's knockback resistance. Head Smash is a melee attack that does damage and stuns the target. Parry allows the Riordan to block an enemy attack and counter it.
The fifth Wizard form is the Aixodue. It is a large green creature that looks like a cross between a lizard and a large feline. It lives and hunts in a shadowy jungle under perpetual gloom. Fade allows it to blend into the scenery, so that enemies cannot see it. This gives the Aixodue the opportunity to make a single, powerful strike from the shadows. Pounce causes it to jump onto the nearest enemy, dealing a significant amount of damage. Maul is an unbelievably fast attack that can be used several times per second, but does a tiny amount of damage. Agility is a passive ability that increases the Aixodue's base movement speed.
Finally, there's the Incorporeal Blob of Nothing Stuff, or IBNS. The INBS comes from somewhere in our world, but from a place that's so strange that it can barely even be comprehended by the Wizard, who lived there as an IBNS. Basically, the IBNS is a large collection of floating balls. Snipity Snipe is its only direct attack, and involves shooting one of the balls that make up its body at the opponent. Envelop is a passive ability that does damage to any enemy that is directly touching the IBNS. Vacuum sucks enemies closer towards it, and Materialize causes it to reappear somewhere else on the screen.
