To become Firestorm, you have to craft the "F.I.R.E.S.T.O.R.M. Matrix". To do this, you simply drop one piece of iron and one piece of redstone next to each other. This will give you a compass which is really the Matrix. Drop the compass to "toggle" your powers. When you turn your powers on, you get a black smoke effect and a ghast/piston extend noise combo. When you turn your powers off, you get a white smoke effect and a piston/saddle noise combo.

First notably, you will probably notice the flame particles. Your head and feet gain fire particles. Now for the abilities.

Flight - To fly simply look straight up into the air, you will be shot up extremely quickly. You will also gain an elytra, so you can glide towards your goal.

Fireball - The fireball is even simpler, just throw your snowball, or "Fireball", at a target and the target will explode. The snowball gains a fire trail

Transmutation - This power is really just experimental. When you walk over iron ore, it changes into diamond ore.

EFFECTS: Strength II, Resistance II, Fire Resistance II
