Annie - The Dark Child
"This is a standard RoA + Mejai's Soulstealer build, basically how to play Annie"
Your Job as a caster all about nuking & CC'ing with an energized Summon: Tibbers. for you to be a successful caster you will need to do well early and mid game, in other words get some kills early on for gold and experience. You are also a suitable ganker hero with your AoE stun and insane nuking abilities. You can also go mid, but it's only good if you can stack Mejai's Soulstealer.
1. Nuker - Can do a lot of damage over a short period of time
2. Stunner - has an AoE stun that can become a gamebreaker in most teamfights
3. Mana Efficient - Can farm up with Disintegrate all day long if you are skilled
1. Golem Dependant - During Late-game you will have issues with mana.
2. First Target - Focused down easily by high DPS mostly physical champions.
3. Little Girl - People tend to be really scared of little girls, I'm just saying.
There is a possibility that going all Magic Penetration can be very useful for Annie, so going up that branch may not be so stupid after all. But for the core item build I have to say Rod of Ages, Sorcerer's Shoes, and Mejai's Soulstealer. Then we have the main item, Rylai's Crystal Scepter, which is the very soul in this build. The rest is pretty much standard as well, I mean Void Staff and Zhonya's Ring. Well that's just what this build is, standard.
Take one point in Incinerate and start casting it 4x times, also buy some Boots of speed for mobility and 3x health Potions. When your Pyromania has reached 4x charges you can go down your lane and cast a last Incinerate on your ally and /Joke. Now that you are energized you can strike fear into your opponents while you are farming, don't be afraid to harass your opponents as your attack range is very large. If you're going mid I recommend taking Disintegrate for last hitting, if you get all the last hits you'll level up by the time you get energized. When you reach level 2-3 you can use Disintegrate to last hit minions, don't worry about the stun, you're better of using Disintegrate to farm up! Remember that the mana is refunded if you kill a minion with it, this will make you last long enough to build Sorcerer's Shoes and Mejai's Soulstealer. Getting First blood is very beneficial for Annie, it will allow you to get the book faster.
1. Disintegrate - Last hit
2. Pyromania - Get Energized
3. Flash - Only if necessary
4. Disintegrate - Stun with it
5. Incinerate - Make sure you hit
6. Ignite - Just to ensure the kill
Now here's a little trick for you all, get 4x charges by farming with Disintegrate and use Molten Shield for the final charge when you are about too attack someone, it's cheesy but it works most of the time and they never knew what hit them. After that you should use Disintegrate or Incinerate for AoE Stun and then use Ignite and auto attack them down. Don't forget to use Flash if necessary and cast Disintegrate and Incinerate whenever they are up. Pedobear can also be used as an AoE stun and is by far the best spell to cast when you are energized! Remember to control your PedoBear with "Alt + click" he dies very fast around towers so micro manage him good, you should keep him as long as you can for the "Immolate + Incinerate" combo on the minions. At this stage you should try to gank with flash -> Summon: Tibbers Stun -> Incinirate -> Ignite while casting -> Disintegrate! Make sure to target the squishes first, or that you backup for stronger opponents.
1. Disintegrate - Charge Pyromania
2. Flash - Only if necessary
3. Molten Shield - Become Energized
4. Summon: Tibbers - AoE stun
5. Incinerate - AoE focus
6. Disintegrate - Single focus
7. Ignite - Just to ensure a kill
By late-game you will either be ignored which is a huge mistake or get focused down easily, remember to use Molten Shield for protection and keep casting Spells for that stun to work! Just nuke everyone out, preferably the DPS'ers first and then the tank, watch your position as it is one of the few defenses you have against gankers. With Rylai's Scepter you will be able to slow with all your spells, like Disintegrate for 35% slow against fleeing enemies, Summon: Tibbers immolate to slow the whole team 15%, Molten Shield to slow melee champions attacking you 35%, and Incinerate for another AoE slow 15%. Don't forget that you will need an Energized Summon: Tibbers every teamfight you are on so grab as many golem buffs and never initiate clashes. You should never walk alone and always be aware of what your opponents are capable of, such as Veigar, Shaco, and Blitzcrank.
Things to watch out for:
Ambushers - They are very annoying as they can just 2v1 and kill you.
Black Shield, Spell Shield - it's really annoying when you're Energized.
Slowers, Stunners, CC'ers etc - Get Mercury's Treads if it's too much for you.
Fed Casters - It's like western gun fight, who gets the stun/ immobilize first?
Have fun with Annie, she's definitely one of the best casters out there
