Captain Rikoris — Epic Seven Light Warrior: RTA Build, Counters & Win Rate

Captain Rikoris is a 3-star Light Warrior built as a speedy support-attacker. His basic Quick Pierce is a single-target spear strike that can lower the target's Defense, and its chance to land improves while he himself has a Speed buff. Cheer grants the whole team a Speed boost for two turns, while his Supreme Spear hits all enemies, strips two turns off every ally's debuffs, and can saddle enemies with reduced Hit Chance and a block on Combat Readiness gain. The result is a cheap turn-order manipulator who speeds up his own side, slows and miss-prones the enemy, and chips at Defense, while sustaining himself through attack-based lifesteal.

Counters

Teams that lean on debuffs to win — Supreme Spear shaves two full turns off the duration of every debuff on his allies, so poison, bleed, stripped buffs, or control inflicted on his team is wiped away quickly, neutering enemies that depend on sticking damage-over-time or lockdowns.
Enemy turn-order and gauge manipulators — His AoE has a chance to block Combat Readiness gain, denying enemies the meter pushes they rely on to act, while his team-wide Speed buff from Cheer lets his side outpace and act ahead of fast-turn compositions.
Dodge and evasion-reliant attackers — Supreme Spear can slow all enemies and inflict Restrict, blocking their Combat Readiness gain so dodge-and-snowball or fast-turn attackers lose the tempo their plan relies on.
High-Defense single targets — Quick Pierce can apply Decrease Defense to a chosen enemy, and that chance rises while he holds a Speed buff, letting him soften a tanky priority target for his damage dealers to finish.

Countered by

Debuff immunity and buff removal — His value is debuffs and team buffs; an enemy that opens with immunity shrugs off his Defense Down, Hit Chance Down, and meter block, while buff steal or dispel can yank away the Speed boost he depends on to even improve his own debuff chances.
Cleanse and enemy debuff-shortening — His applied debuffs are only chances and last two turns, so a cleanser removes them outright and an enemy that shortens debuff durations cancels his slows, miss-prones, and Defense break before they matter.
Unhealable pressure and burst before his cooldowns — He has no self-sustain, no passive, and his key tools sit on long cooldowns (Cheer six turns, Supreme Spear five), so simply bursting him down or pressuring the long windows where he has no AoE control works.
Faster, harder-hitting bruisers — He is a slow-band, modestly-statted 3-star whose own basic is single-target; opponents who outspeed him before he can fire Cheer, or who simply hit harder, overwhelm him in straight trades.
