Since the launch of the new items in the Pre-Season 2021, many believe that assassins or fighters dealing physical damage have a distinct advantage over mages in the current meta. However, the truth is that if mages choose the right Mythic items, they can possess power that rivals other roles in League of Legends.
And here are the most suitable Mythic items for each type of mage:
Riftmaker

As the cheapest Mythic item for mages, Riftmaker has an intrinsic effect that boosts allies’ damage to enemies after you control (slow or immobilize) the opponent. Therefore, this item is quite excellent for support mages who want to increase damage and movement speed to chase or escape from enemies, suitable for champions like Xerath, Vel’Koz, Janna, Zilean,… (champions that can activate the passive Synergy with just one skill in the bot lane).
Hextech Rocketbelt

Among the current Mythic items, Hextech Rocketbelt is somewhat less appealing to players. But it remains a convenient item for mages who want to quickly approach their targets to deal damage as quickly and as much as possible. Suitable for champions like Fizz, Ekko, Lissandra, or Ahri,…
Shadowflame

An upgraded version of the Hextech Gunblade, Shadowflame provides many champions with a substantial power spike over other items due to its 15% total omnivamp stat. In the current meta, this Mythic item is most suitable for fighter-mage champions who favor extended engagements like Mordekaiser, Shyvana, Sylas, Swain,… or some special champions that previously needed the Hextech Gunblade like Akali or Katarina,…
Night Harvester

This item is designed for burst damage for assassin mages, but its overpowered passive of dealing an extra 175-250 (+15% AP) magic damage has made it a must-buy item for everyone. For example, champions like Karthus, LeBlanc, Zoe, Lux,… can all purchase and utilize this item well, becoming (almost) exponentially stronger when combined with the Sorcery Keystone Dark Harvest. Due to its overpowering nature, this item will receive a damage reduction in patch 10.24 to balance against other Mythic items.
Liandry’s Anguish

Similar to Liandry’s Torment in dealing damage based on max health percentage, this Mythic item is still suitable for poke mages who deal consistent damage over time, such as Vel’Koz, Morgana, Malzahar, Brand,…
Luden’s Tempest

Like its predecessor Luden’s Echo, Luden’s Tempest also shares the main purpose of providing mana, reducing cooldowns, and having a passive for wave clear (as well as dealing light damage). Basically, this is a fairly basic item that any energy-based mage can purchase.
Everfrost

This is a special Mythic item for mages with the ability to slow or root enemies for 1.5 seconds. And since it provides a lot of stats from ability power, health, mana, and cooldown reduction, it is very suitable for fighter or tank-like mages who like to stick to enemies like Lissandra, Cho’Gath, Sylas. Or if you want, you can also buy it to activate and increase the hit rate of important skills like Ahri’s E, Zoe’s E, Vel’Koz’s E,…
