Hail protectors, let's take a look at the beast blaster that is Stargirl.
Stargirl is great at poking and her range is incredible. Add to this the ability to slow you down and steal your health, she's a dangerous foe to lane against. It's all about inflicting maximum power damage from a distance. Although Stargirl is a beast at ranged attacks escape can be difficult, bear this in mind.
This guide has been created primarily with Coast City in mind but this build could be applied to Heights and Divided easily.

Stolen Powers:

Flash's Super Speed
Super Speed is a must have for Stargirl just to have an extra boost when escaping. Stargirl is all about range and poking the enemy but if you get ganked escape can be difficult.

Poison Ivy's Healing Wave
This stolen power is also useful when trying to escape, any heal would do the job, I just like this one.

Although these stolen powers seem like simple choices they can be extremely useful when trying to escape, something that Stargirl requires.

Items:

Start off with the Nil Ring and the Energy Lance to provide a nice balance between power damage and health to help the early game. From here continue to build the Energy Lance and move onto the Cosmic Staff. The next items to build are the Starheart, Book Of Eternity and Doctor Destiny's Dreamstone. At this point Stargirl will be doing some nice power damage, if you feel that the enemy is inflicting too much damage then you could consider buying items that give Stargirl a nice health boost whilst still inflicting power damage, such as the Cosmic Belt or the Royal Atlantean Seal. If you feel that Stargirl needs some armour then Ra's Al Ghul's Robe and Neron's Contract are viable choices. I usually concentrate on building Stargirl with as much power damage as possible and only build defensively when required.

Mods and Augments:

It's all about power! The selected mods and augments are used to give Stargirl that extra boost to make her even more dangerous.

Abilities and play style:

Passive - Family Heirlooms
Stargirl's passive provides a nice buff for her Q (her best move) as well as providing increased movement speed when she hasn't taken damage for 10 seconds.

Q - Cosmic Blast
This move is the greatest weapon in Stargirl's arsenal. The range is great and the damage is strong. Unlike other champions ranged abilities, Cosmic Staff inflicts equal damage to all enemies hit. Use this to poke at the enemy and to defeat multiple bots at once. This move should be prioritised when leveling her abilities.

W -Shooting Stars
This move marks the enemy and fires four stars, one every 0.4 seconds,each dealing power damage to the enemy. This is another move that has good range and is useful when trying to push an enemy. This move can be dodged fairly easily, so try to mimic the movement of the marked enemy to ensure as many stars hit as possible

E -Gravity Well
Gravity Well is great when initiating a fight. This ability slows the enemy and increases the amount of power damage inflicted from Stargirl by 10%. As well as initiating a fight, gravity well can be effective when trying to escape.

R -Energy Conversion
Stargirl's ultimate provides a decent amount of power damage whilst generating a shield and resetting the cooldown on her passive. The target is initially crippled (cannot use any abilities) and dealt power damage for 3 seconds. It is important to remember that if the distance between Stargirl and her enemy becomes too great the move will cancel. Try to use this move when you can guarantee that the enemy will be in close range, the generated shield will be active for three seconds after the connection is lost. This move is great at dealing damage whilst providing protection, ideal in a close one on one encounter.

Whilst laning, use Q to poke at the enemy and clear multiple bots. When the enemy is becoming too close for comfort, use W to remind them who's in control of that lane. When Stargirl goes into full best mode on an enemy be sure to drop E first to slow them, use W to get in multiple hits from those stars and while the enemy is crawling away line up that Q and finish them. If you are still close to enemy then deploy her ultimate to ensure you get that kill.

In a teamfight throw down E to slow as many targets as possible. Although W is easy to dodge one on one, in a teamfight the chances are that those stars are going to hit someone. Q is great at damaging multiple targets and R can be deployed to pick out a single enemy and hopefully provide enough of a shield to escape the potential aftermath of a team fight.

Overall, Stargirl is great at dealing large amounts of power damage from a distance. Try to remember that she is vulnerable and doesn't have a lot options when trying to escape. Poke the enemy from a distance and try to stay with the team as much as possible, if you try and be a hero it probably won't end well.

Thanks

Thanks for reading this guide and have fun with Stargirl, she's almost my favourite character (Aquaman is a BEAST!). I would like to thank DMCtheHEDGEHOG for helping me perfect Stargirl by playing approximately three million and one games with me.
