In "Underground Castle 4: Knight and the Shattered Chronicles," there are many outstanding characters, especially how is Helena in Underground Castle 4? Helena is an all-around support character with healing, buffing, and crowd control abilities, playing a core role in the team to maintain health and break enemy defenses. If you have her, you can easily form a powerful lineup, capable of overcoming challenges against any type of boss.

1. Skill Introduction
Her core skill is called Sacred Prayer, which, when used, restores 15% of the team's health and applies a 20% damage reduction shield for 5 turns. It is suitable for pre-shielding before boss fights or dealing with enemy AOE skills. Her offensive skill is called Holy Judgment, which deals 200% magic damage to a single target and reduces its defense by 15% for 3 turns, making it a powerful output skill.

2. Team Composition
Given that Helena is positioned as a semi-support and semi-DPS, she can be paired with Fiona (Tank) + Helena (Support) + Fire Mage/Nightingale Assassin (DPS). At the start, Fiona can taunt and absorb damage, while Helena provides shields and armor reduction, and the Fire Mage/Assassin delivers burst damage. This composition is generally adaptable to most combat situations, with the option to switch out one character based on specific needs.

If you encounter very challenging dungeons, you can switch the lineup to Swift Arrow (Trap DPS) + Mora (Crit DPS) + Helena (Crowd Control + Armor Reduction) + Fiona (Tank). After the battle starts, use Helena's chance to stun to interrupt the boss's skills, working in tandem with Swift Arrow's traps and Fiona's control to create a loop.

3. Combat Tips
When fighting bosses, try using Sacred Prayer one turn before the boss releases an AOE to reduce team damage. Use Holy Judgment to deal extra damage when there are 3-4 small monsters left, to avoid wasting it. In terms of positioning, place Helena in the back row (3rd row) to avoid being targeted by the boss's charge or AOE attacks.

For equipment selection, prioritize attack speed gear (such as triple attack speed setup) to improve skill cycle efficiency. At level 30, it is recommended to invest talent points in damage resistance to enhance survivability; at level 90, you can choose probability sniping to increase crowd control ability; and at level 150, select the right-side talents to strengthen support effects.

4. Usage Scenarios
This character can be used in high-difficulty dungeons such as Tomb 270 and 300 layers, relying on her armor-breaking and crowd control abilities to deal higher burst damage. In PvP arenas, she can effectively coordinate with high-burst teammates to quickly eliminate the enemy core. In the Forgotten Tomb, the continuous healing and damage reduction she provides significantly increases the team's fault tolerance.

If you plan to tackle more varied combat scenarios, it's worth knowing how Helena performs in Underground Castle 4. Helena is an all-rounder support, capable of both protecting teammates and assisting in dealing damage, excelling in various types of battles. Mastering her skill timing and team composition can greatly improve your clearing efficiency, making your gameplay much more enjoyable!
