Predecessor Builds > Riktor > Riktor Support [Tank] (still works great in v13!)
Very standard build for Riktor as Tank-Support. Crest can be Rift Walkers for engaging or Sanctification for sustain
Get the early mana and powerspike from Fire Blossom (also effective for gaining support income without actively hitting lane minions), apply pressure to enemy ADC whenever he hits you with Tainted Guard.
Got ganked by enemy mid? Get Flux Matrix for the magical sustain and little magical power amplification, from there you can follow up with Dynamo (phys armor + debuff), Stonewall (phys armor + stun), Crystalline Cuirass (mag armor), Void Helm and so on... Depending on the team combination of both teams, I like to finish with Stonewall or Dynamo and World Breaker/Spellbreaker
smol tipps - RMB: Dont directly aim for the enemy, let the enemy walk into your crosshair! If u try to engage and miss, instantly fall back to prevent bad trades. Also setting the ability cast to instant can help increasing the skill. Take advantage of your passive for engagements especially in early game!
And guys, Riktor is a very big boy - becoming a meatshield (blocking enemy projectiles while simple standing in front of your carry) is a necessity that every support player should do if required! ❤️
