The different weapon combinations available to you make you a very versatile ADC who can adapt to nearly any given situation (provided you don't fall back massively in the game).
The AoE damage on your Infernum UltimateRas well as the potential to CC an entire enemy team with your Gravitum Ultimate Rmakes you really good during team fights (especially in closed and clumped fights).
You excel in extended trades with slight variations depending on your weapon combination. Combined with the sustenance from items and your Severum, you can easily turn the tide of a fight if you manage to survive the enemy's attempt to kill you at the start of a fight.
You're quite immobile which can make you a prime target for chain CC and assassins. You rely on extended trades, so taking you out quickly will give the enemy team a huge advantage (especially if you have your Infernum W up when you die).
Some weapon combinations are really bad on you and don't synergize well. This can lead to periods where you can't retaliate as effectively as your counterpart. Avoid fighting until you get a favorable weapon combination.
You are item reliant during the mid-game. If you are camped constantly early on, you won't be able to farm freely and will have a hard time as the game goes on. Also, the enemy team will look to fight you when your Ultimate R is down, so be very careful about initiating a fight during this time.
0 - 15 min
Focus on farming early on so that you can get your first item as soon as possible. Save your Severum ammo if you can as the Q will be useful for trading in the lane if your Support initiates a fight.
You may play around your Support/Jungler and set plays for them with your Gravitum Q. At no point, should you get too close to the enemy (even if they are CC'd).
When equipped with the Infernum, you will become a gank target as you will automatically push the wave. Do your best to not let that happen and ask you Support to thin out the wave evenly so that you can farm properly.
15 - 25 min
Now you can start saving up on your Infernum ammo as the Ultimate R will come in really handy during an objective fight.
Although you have hit one of your power spikes, you will still have to maintain your distance from enemy champions who have hard CC in their kit. You may also need to be reactive (Flashing when someone uses Flash to try and CC you) and build appropriately (Grievous Wounds for example).
Don't mess up the lane assignments and try to stay mid when possible. The lane is shorter and will allow you to escape assassination attempts with ease while being able to farm easily. You will also be able to get mid priority which can be translated to objectives.
You should get at least one defensive item depending on the enemy team comp and fed carry as you will be a prime target. Always keep an eye out on your flanks and prioritize saving yourself.
Don't get caught out trying to farm a side lane at this point. Neutral objectives are important at this point so always try to stay near the lane where the objective is about to spawn in the next few minutes.
If you manage to find a pick on someone, don't hesitate to use your Ultimate R to finish them off. Your Ultimate R cooldown should be quite low at this point but do your best to save some Infernum rounds for a major fight.
After Aphelios’s first back, he would have picked up his first damaging item. He can look for more favourable trades with the enemy once he has purchased his first component item.
When Aphelios has hit level 6, he gets his first major level power spike. Unlocking his Ultimate R offers him a lot of trading and kill pressure.
After Aphelios has completed his Mythic item, he’ll be comfortable winning trades with the enemy. This is especially true if he gets his Mythic item before the enemy ADC.
Aphelios is good in mid-game team fights thanks to the potential of his Ultimate R and the mix of his weapons. As long as he didn’t fall behind in the early game, his mid-game will be where he truly shines.
During the mid-game, Aphelios should’ve completed multiple items. He will start to dish out a lot of damage, and he will find it much easier to take down the enemy frontline.
Aphelios is a good mid-game champion, especially when paired with a utility Support or a team that can empower him. Healing and shielding, or hard engage Supports will definitely help him shine in the mid-game.
Aphelios’s late game is also strong. Although while you’re good in the late game, it is important that you do not over aggres as Aphelios is very squishy.
In the late game, Aphelios will be full build or nearing completion of his build. He will be able to dish out a lot of damage in late game team fights.
Aphelios is a strong team fighting champion. He should group with his team and play as 5. He will be able to melt tanks at this stage of the game, as long as he watches his positioning and doesn’t get caught out.
