Jena

Jena is a 3-star Ice Mage built around crowd control and tempo denial rather than raw damage. Her basic staff attack has a 35% chance to stun for a turn, her second skill is a non-attacking spell that shortens every enemy's buff durations by one turn and freezes the whole team for two turns, and her third skill hits all enemies with frost magic that can cut their Defense and then knock back their turn meter by 20%. She is a slow disruptor with no passive, leaning on her freeze and turn-meter push to stall fast or buff-stacking teams.

Counters

• Teams that rely on stacking buffs before they strike — Her second skill is non-attacking and trims one turn off the duration of every buff on the enemy side while freezing them, so opponents who pile on attack, crit, or speed buffs to set up a big turn lose that setup before they can cash it in.
• Fast enemies racing for the first move — Her third skill hits all enemies and can push their turn meter back by 20% on top of freezing them with her second skill, letting her steal tempo from teams that depend on going first.
• High-Defense frontliners and bruisers — Cold Snap can decrease the Defense of every enemy for two turns, softening tanky targets so her own team's follow-up damage lands harder.
• Single dangerous threats she can lock down — Her staff attack has a 35% chance to stun for a turn and her freeze adds another layer of hard crowd control, so a key enemy can be repeatedly denied its turn.

Countered by

• Cleansers — Her whole value is the freeze, Defense break, and turn-meter pressure she applies as debuffs, and a teammate or skill that clears those debuffs wipes her contribution in one move.
• Effect immunity and resistance — Her stun, freeze, Defense break, and turn-meter push are all chance-based debuffs, so enemies protected by immunity buffs or high Effect Resistance simply shrug them off and she is left doing little.
• Fast, hard-hitting attackers — She is slow and has no passive or self-protection, so opponents who outspeed her can burst her down before she ever lands her control.
• Pure damage-race teams that ignore debuffs — Her kit applies disruption rather than meaningful damage, so an enemy team that simply out-damages hers can win before her stalling matters, especially if her stun and freeze rolls miss.
