Space Groove Riven Emblem: Trait Value and Late-Game Cap

Play this only with a Space Groove Emblem, ideally found before 3-6. Do not force it without the emblem, because the comp relies heavily on Riven keeping the Space Groove buff active.

At level 8, use Pantheon, Gwen, Ornn, Riven, Tahm Kench, Nunu, Nami, and Blitzcrank for 5 Space Groove with the supporting frontline and backline traits. If you have not found Blitzcrank yet, use Nasus temporarily.

At level 9, add Shen to cap the board. 7 Space Groove is usually not worth prioritizing unless your expensive units are still missing or low quality.

The key emblem is Space Groove Emblem on Riven. Extra Timebreaker Emblem can go on Blitzcrank, while extra Vanguard Emblem can go on Tahm Kench.

Backline carry Nami wants Jeweled Gauntlet, Nashor or Spear of Shojin, then any AP item. Space Groove already gives attack speed, so prioritize one strong starter item; Nashor pairs especially well with Jeweled Gauntlet.

Melee carry Riven must hold Space Groove Emblem, then Bloodthirster plus Edge of Night or Titan. The emblem supplies enough damage, so survival is the priority. Avoid Sterak if possible because it shifts her damage profile toward physical and lowers the value of AP shred.

Nunu or Tahm Kench can be the main tank. Build normal frontline items and prioritize Nunu when both are the same star level.

The comp works because Space Groove Emblem gives its holder a 3-second Space Groove buff after every cast, while 5 Space Groove keeps stacking offensive stats. Riven has only 20 mana, so she can chain casts and keep scaling through the whole fight.

If Graves appears early, he can use a similar idea with the right divinity setup, especially Power Frame plus Cooling Medium, and can even beat a 3-star Corki board when the setup lands.

Place Blitzcrank in the corner so he can trigger early, or move him to mark the enemy main tank. Gwen has 2-hex range, so this setup keeps her from getting body blocked. Nami sits in the back corner while Nunu and Tahm Kench absorb the first wave.

Prioritize augments that can create a Space Groove Emblem. After that, look for one item augment plus one combat or economy augment. Electrocharge is especially strong because the board uses many melee units.

Ekko is the first choice, followed by Evelynn, Aurelion Sol, and Thresh because they can offer Space Groove Emblem around 2-4. Avoid Ahri: 5 Space Groove already gives offensive stats, so her blessing adds less and can make outside level-9 boards come online more easily.

In the early game, let Teemo or Milio hold Nami items while Talon holds Riven items. Add traits as you go, then level based on board quality: 4 on 2-1, 5 on 2-5, and 6 on 3-2.

Go level 8 around 4-2 and roll hard for the recommended board. Depending on HP, roll again around 4-5 or 5-1 until you have two upgraded 4-costs plus one extra 4-cost pair, then save economy because Tahm Kench can feed more copies.

At level 9, add Shen and look for 2-star Blitzcrank to finish the board. If other level-9 boards have already capped, you can stay level 8 and chase 3-star Nami or Riven.
