I would like to specify that this guide is NOT for completely new Aphelios players. I advise that you play Aphelios first to understand the core basics of his kit, as I will not fully go through his abilities here, If you're first timing Aphelios after reading this guide, you may find this difficult. Once you feel you understand his basics, please come back to this guide.

In the Laning Phase, you're going to want to work on getting Severum + Crescendum in most scenarios.

You should probably know that Aphelios's Gun Order is Calibrum (Long-Ranged Tool), Severum (Healing + Chakram Stack Tool), Gravitum (CC Tool), Infernum (Wave Clear + Quick CC Tool) and Crescendum (Destroying The Enemy Tool).

If you're playing against something you'll need a lot of poke for, I'd generally start using severum for CS'ing, and saving Calibrum for some poke when needed. Anorher useful tip is that having Calibrum + Gravitum can make a long ranged CC tool, by Calibrum Q'ing and then switching to Gravitum to Q and perform the root.

If you're playing against a normal matchup, try to rush Severum + Crescendum. CS with Cailbrum, Gravitum and Infernum and save your Severum exclusively for the Q ability when you get Crescendum. Play safe until this point, and if you feel ready to go in, or a gank is performed, quickly Severum Q to gain many chakram stacks, then switch immediately afterwards to Crescendum to use the chakram stacks to gain a ridiculous amount of attack speed and damage for a few seconds. Hopefully this will let you end your enemy.

Gravitum + Infernum is a fantastic team fight weapon combo that is a must use for team fighting. Infernum Q will put the effect of your Gravitum auto attack orbs on any enemies in the cone area, and switching to Gravitum and pressing Q will root all the enemies, allowing for a quick team fight victory. Also, don't forget you are a marksman, and should not be front lining.

Calibrum + Severum
Synergy: 1/3
This is the base combo guns you will start out with at the beginning of the game. These two guns synergise pretty poorly, and you should generally try to get rid of this combo frequently.

Calibrum + Gravitum
Synergy: 2/3
As explained in the Laning Phase section, this gun Combo is a great long ranged CC tool that can be used in many situations to save you or another's life, or to secure a kill that otherwise might not be possible.

Calibrum + Infernum
Synergy: 1/3
Sometimes the marks with Infernum Q and be useful but generally this isn't the best combo you should be going for.

Calibrum + Crescendum
Synergy: 1/3
Also pretty situational, but generally not all too useful.

Severum + Gravitum
Synergy: 2/3
Applies quick CC that's quite useful.

Severum + Infernum
Synergy: 0/3
You get practically nothing out of this.

Severum + Crescendum
Synergy: 3/3
Aphelios's most disgusting damage tools. Severum Q into so many chakram stacks is absolutely ridiculous and insanely good if you can utilise it properly.

Gravitum + Infernum
Synergy: 3/3
Very good team fighting gun Combo for quick cc on many different targets.

Gravitum + Crescendum
Synergy: 0/3
This combo sucks. You can't get any chakram stacks out of Gravitum so it's essentially pointless. Get rid Of Crescendum ASAP to get Infernum for that teamfight CC beauty.

Crescendum + Infernum
Synergy: 1/3
Has situational use whet its pretty good but other than that it's not really all that good.
