If I had known how useful Air Superiority could be when I soloed Dr. Vhazilok, I probably wouldn't have died at all! (I had one death during the fight)

At this level, just some basic attacks, and fly as a travel power. I use Air Superiority for the prerequisite because of it's great utility for keeping enemies on their butt and keeping you safe in the process. When soloing at low levels or when you have the aggro of a tough enemy, using Air Superiority can save you.

Builds for a fire blaster are fairly simple. They're straight damage so there isn't a lot you have to think about as far as which powers to pick (unless you want to get creative with pool powers). Here's my build up to level 30.

For me personally, I skip travel powers until later due to the various temp powers you can get that make them unnecessary (see my travel-tips guide for details).

The AoE combos you can use with a Fire/Fire/Fire blaster would make a pyromaniac wet his pants with joy.

At this level, you have pretty much everything you need to kick butt. You have a good single target chain and a good AoE chain too. Because you have enough powers at this point, you probably won't use flares much unless you want to keep your distance and aren't close enough for melee attacks or Blaze or if you're stunned.

If you still have Air Superiority, remember to use it to control difficult targets.

Using Build Up and Aim together works really well for single powerful attacks like Blazing Bolt, Inferno, and Rain of Fire. In most other cases, it's better to alternate them (Aim, attack, attack, attack, Build Up, attack, attack).

For AoE combos, target someone in the middle back of a group and press the "follow" key. Use Fire Breath as soon as you're close enough, then use Fireball. As soon as you're in the middle of the group, hit Fire Sword Circle.

If you are still alive at this point and so are they, use Rain of Fire to slow and scatter the rest of the enemies (as well as killing any that are clinging to life).

Your power additions in these levels really just augment your awesomeness:

• Consume helps you keep rocking, but is also necessary for the Nova+blue inspiration+Consume combo.
• Burn not only frees you from immobilize (which immobilization is one of the key reasons I died in lower levels since I couldn't run away), but it also makes a great addition to your AoE combo. After Fire Sword Circle, use Burn since Burn drops right at your feet and you're already in melee range after using Fire Sword Circle.
• Melt Armor is great for weakening tough enemies, just be sure not to waste it on weak targets that it's not necessary for.
