Advice to face Malphite
Malphite counter champions
These are the champions I highly recommend when it comes to finishing off Malphite. These champions possess great skills that become immune to Malphite.
Trundle has good resistance against this and good ice skills. As we know Malphite is slow in his mobility, against Trundle this will be slower than a turtle, causing it to spend its utimate unnecessarily to escape.
Rumble is pretty good also against Malphite, as Malphite is melee and slow is a plus point for Rumble, as he has a large R that causes magic damage that is +30 of ability power, causing much more damage as he spends time 130/185/240 damage to the one in his R zone, it also decreases mobility to the one in his zone. This utimate ends all League of Legends melee without mobility.
This bone shredder is very strong against Malphite, as Illaoi pharmacies fast and resists in line causing no body to body to finish with her very easily. Illaoi waits for Malphite to throw his E and R and finish him in a few simple blows of utimate. If you use this champion arm yourself properly, so as to get a lot of advantage to Malphite.
This champion has good skills to face Malphite, Yorick with his Q causes damage and healing as well as when it hits, being this that the little damage that Malphite does to the champions that damages quarpo to body is nothing against this. Yorick with his W can throw it when Malphite throws his R. This is a waste of time for Malphite to keep moving forward.
Malphite counter items
Rylai crystal scepter
This item is quite good against Malphite, as it neutralizes the mobility of those who are reached by some skill of a magician. This helps a lot when Malphite is in a situation without R it will be quite easy to end up with Malphite being slower.
Filo de la noche
If this item is used very well it can immunize from the R of Malphite to the one who possesses it. This item is highly recommended for adc or murderous roles.
