How to Play Solar — TFT Set 18: Enchanted Wilds

Everyone loves a good reroll trait, and this set we have Solar! 

Once you have 3 Solar activated, your champions gain a max Health Shield and will also do bonus magic damage. But here's where the fun comes in: you will gain additional bonuses for each unique 3-star champion on your board, so the more the merrier. 

Some of the effects are crazy, to name a few, you can increase the shielding and magic damage for each 3-star, Convert the bonus magic damage to true damage which can be insanely strong against tanky frontlines, Lastly your 3-star champions ascend to 4-star during combat, yeah you heard that right, you can have a bunch of 4-star champions on your board at once, sign me up!

So let's get into the champions and learn more about the Solar Trait.

Solar Champions and Synergy

  • Kayle - Rapidfire
  • Sejuani - Juggernaut
  • Lux - Avatar

TFT Solar Champions

Leona Defender Shieldbash Solar 1g

Leona’s ability Shield Bash has both an active and a passive. The Passive is pretty strong and makes Leona start combat with bonus resistances that decay over time. This is perfect and will be great with the solo frontline strategy, as Leona will be at her strongest at the start of combat, so you’ll want as many units as possible focusing her. 

The Shield Bash active makes it so Leona bashes her current target, dealing magic damage and also stunning them for a short period of time.

Kayle Rapidfire Solar 2g

Set 11 Kayle was everyone's favourite, along with set 15, with certain power-ups, as the unit can become a damage-dealing machine. In set 18, it's no different, as Kayle can ascend based on her star level, granting her stacking bonuses. Let's get into them. 

Her 1st Ascension makes it so her attacks deal bonus damage, not bad for a 1-star. Once 2-star Kaye’s attacks shred enemies, making it so you don’t need to build Void Staff or Ionic Spark. 3-star Kayle attacks fire waves, dealing magic damage to all other units hit, which will significantly increase her damage input. Lastly, her 4th Ascension makes it so Kayle gains infinite range, and every 3rd wave is much larger, which will make her easily one of the strongest 2-costs of this set.

Sejuani Juggernaut Solar 2g

Seijuani’s ability, Sun’s Wrath, grants her a shield which will decay over a period of time. Then, cleave in a cone, dealing magic damage and strike in a line, dealing magic damage to all enemies hit. With 3 items and potentially 4-star with the Solar trait, that will be one tough boar to take down.

Lux Avatar Solar 5g

Lastly, we have our 5-cost Solar, Lux. Similar to Set 2 Lux, Lux can fit into almost any comp as she can be bought, sharing the same trait with most origin traits. For this comp, we want Solar. 

We want Solar so bad, as her passive makes it so whenever Lux casts her Final Spark ability, all allies that share a trait with Lux gain mana, making all your over Solar units even stronger in team fights. 

Lux’s Final Spark spell fires a massive laser towards the largest group of enemies, dealing loads of magic damage. The Solar Bonus weakens enemies hit by the laser as well, which reduces the damage dealt, making the enemy have an even harder time getting through your frontline.
