Redangry Rift - Hero Combos (Assume you have a Tank/Vanguard)

HeroesRedRift0.5.2 Redangry30 ranked
S
Author's note: An early Rip B w/ Rush trigger HP gain alongside Nyx ends up causing him to be one of the best tanks in the game. You can always sideline him later and still get most of the benefit of your previous work if a high ranked Vanguard shows in the shop too.
Author's note: Irini's Active skill scales with the number of Rush/Stall triggers, and Nyx provides way more than anyone else in the game as a single character. Enough that Irini B can carry the entire RR if your Nyx was online early.
A
Author's note: These are the most consistent characters for Shard Generation builds. If you get the option for Shard Generation = shields/damage very early and you have one of these characters you can usually force this build. A+ Assassin with Shard Collector = win, too.
B
Author's note: Kai - The Unstoppable with mystics is a solid build that can clear with only a B rank Kai. Depending on what you have seen you may want to run a tank with this build and buy a 4th character slot. Grace makes the list simply for The Radiant.
Author's note: Sal's The Breezy combined with duelists that can apply debuffs is very potent. Karsu is a decent character with her The Frostbite spec, as she now begins to gain attack speed fairly quickly. Nyx The Spark again. Irini and Tilly need items that apply debuff
C
Author's note: Funke - The Stoked. Similar plan to Kai + Mystics which is to scale out of control during the battle. Grace The Radiant is great here too with Pollen/Aria. Requires ranks on Funke to be strong, and The Detonator is also really good so this is not common.
D
Author's note: Funke - The Detonator (greed edition). With enough Rush triggers (thus Nyx's inclusion) Ming - The Searing puts up insane amounts of Burn. Then Funke kills everything that is stacked up. A strong transition if you had Nyx+Rip early and found a Funke+Ming.
Author's note: Despicable build where you have enough shields that Fiona's The Lustrous actually procs a lot, and Funke detonates them.
F
Author's note: Warrior Rush. If you get all of these characters high rank quickly and get Rush extension relics/items this can be good. F because it's really hard to pull off in RR and you will likely die trying.
