Abilities INNATE: Aphelios has access to an arsenal of 5 Moonstone Weapons, created by his sister Alune. He equips two weapons at any one time, one as his main weapon and one as his off-hand. Each weapon has a unique basic attack and passive effect.

Aphelios begins the game with Calibrum as his main weapon and Severum in his off-hand, with Gravitum, Infernum, and Crescendum queued in reserve. The queue order can be rearranged based on weapon usage.

MOONLIGHT: Weapons spawn with 50 Moonlight for ammunition, which is consumed on basic attacks or to cast his Q abilities. Abilities that cause Aphelios to attack do not cost additional Moonlight on top of their ability cost. Once his main weapon is exhausted of Moonlight, it is moved to the end of the queue and Aphelios equips the next available weapon from his reserve.

WEAPON MASTER: Aphelios cannot improve his abilities with skill points. He starts the game with Phase and gains access to Q abilities at level 2. He gains access to Moonlight Vigil Moonlight Vigil at level 6, which improves automatically at levels 11 and 16. Instead, Aphelios may spend his skill points to gain bonus attack damage, bonus attack speed or armor penetration.

Flash
It will be mandatory. It is self-explanatory. It is valuable as a tool to make plays, chase down, kite away, escape, ruin a gank, etc....
Heal
You should be taking heal as it'll be great for 2v2s, movement speed for clutch plays or escaping, as well as being able to save allies.

Doran's blade + 1 Potion
Doran's blade is pretty standard on most botlaners these days and that includes Alphelios! It provides a good balance of AD, health, and lifesteal to help in trading, fighting, and all-ing.

Doran's shield
doran's shield is very good against aggressive match ups like lucian, draven, cait giving you sustain in laning face

Riot really did take the laning phase in consideration with the way his guns are lined up. The first two guns you start with is Calibrum the Sniper Rifle and Severum the Scythe Pistol. The Sniper Rifle will be used to poke the enemy with auto-attacks or laning Q's and marking them. Secondly, you'll have the pistol which provides a lot of healing. So whenever you lose HP due to trading, getting poked, or fighting make sure to use the pistol to heal that lost HP back! The third gun after one of these are gun will be Gravitum the Gravity Cannon and you'll want to use it to snare someone to make a play in the 2v2. Then comes Infernum the Flamethrower which can be used to shove the lane, gain Chakram stacks, or straight up right click the enemy or minions to get bounced off damage. Lastly, you'll have Crescendum the Chakram to setup plays with Q or gain stacks to have high DPS in skirmishes.
