Helga — Epic Seven Earth Warrior: RTA Build, Counters & Win Rate

Helga is a 3-star Earth Warrior built around single-target axe hits that stack Defense Down. Her basic attack can apply Defense Down for 2 turns, and her main skill (2-turn cooldown) slams one enemy with a 75% chance to apply Defense Down, with a critical hit having a 50% chance to extend her own active buffs by 1 turn. Her 5-turn team skill is non-attacking: it grants allies Attack Up for 2 turns and then pushes her own Combat Readiness by 50%, letting her act again sooner. She has no passive and every offensive skill hits one target only, so she is a support-leaning bruiser who softens a single priority enemy while buffing her team's damage.

Counters

Tanky single targets — Her basic attack and her 75% main skill both apply Defense Down for 2 turns to one enemy, so she chews through a high-Defense boss or a beefy front-liner that her allies then focus down.
Damage-reliant allied compositions — Her team skill grants Attack Up to allies for 2 turns and then pushes her own Combat Readiness by 50%, accelerating an aggressive team's burst window while she keeps stacking Defense Down on the target.
Enemies that stall a turn out of her — A critical hit on her main skill has a 50% chance to extend her own buffs by 1 turn, and her self Combat Readiness push lets her cycle back fast, so foes hoping to outlast her buff timers can be denied that window.

Countered by

Cleanse and Immunity — Her offense leans on stacking Defense Down on a single target; allies or enemies with cleanse remove that Defense Down, and Immunity blocks it from landing at all, neutralizing her main contribution.
Buff removal and theft — Her value also comes from the Attack Up she hands her team; heroes that dispel or steal buffs strip that Attack Up and can take her own extended buffs, undercutting the team-damage payoff.
Buff-duration shortening — Her critical-hit buff extension and the 2-turn Attack Up matter on timing, so enemies that reduce buff duration erase the extra turns she works to bank.
Multi-target and spread threats — Every attacking skill she has hits only one enemy, so she cannot answer wide AoE pressure or peel for a whole team — she only ever softens or focuses one target at a time, and her team buff sits on a long 5-turn cooldown.
