Overview

Kroa, the Dark Harg in Summoners War, is a 3★ Support monster known for her high base Speed and utility in turn-cycling compositions. Summoners War Kroa Dark Harg boasts a base Speed of 120 when awakened, making her one of the fastest natural 3★ monsters in the game. This speed makes her especially valuable in early turn control and buffing roles. Her skills focus on manipulating the Attack Bar (ATB), applying speed-related debuffs, and providing supportive utility to her allies.

Her first skill, Breeze, is a basic attack that also boosts the ATB of the ally with the lowest bar by 15%, allowing smoother rotation in fast-paced teams. Her second skill, Wood Vine, offers crowd control through an ATB reduction and Speed debuff on a single target, with damage scaling off both ATK and DEF. Her third skill, Owl’s Hoot, grants the entire team a Speed buff and a heal-over-time effect for three turns, followed by an immediate turn for herself—making it perfect for turn-chaining and prolonging team uptime.

Despite her 3★ rating, Kroa shines in specific PvP situations, particularly in Arena and Siege where turn one speed is crucial. She has seen niche usage in RTA (Real-Time Arena) for players who build around speed leads and denial strategies. Some players pair her with nukers like Lushen in siege offenses to ensure they outspeed and clean up quickly. However, her usability is limited in PvE or prolonged fights due to a lack of strong survivability or offensive power.

How to Obtain

Temple of Wishes

Light and Darkness Scroll

Kroa (Dark Harg) can be obtained exclusively through non-guaranteed summon methods in Summoners War—specifically from Light & Darkness Scrolls or the Temple of Wishes. She is a natural 3★ Support monster, and these are her only legitimate summoning sources.

This means she is not farmable—she cannot be acquired in a Secret Dungeon (e.g., Hall of Darkness), nor is she obtainable via guaranteed fusion or in-game events. If you’ve pulled Kroa, she most likely appeared from an LD scroll or from the random pull in the Temple of Wishes.

Strategy

Kroa (Dark Harg) excels as a fast support unit focused on controlling the flow of battle through speed manipulation and team sustain. Her high base speed allows her to act early in the turn order, enabling her to quickly boost allies’ Attack Bars and apply speed debuffs to enemies, which can disrupt opponent strategies and give your team a crucial advantage. Her third skill provides a multi-turn speed buff and healing over time, helping to keep your team alive while maintaining momentum.

Kroa is particularly effective in PvP modes like Arena, Siege, and RTA, where turn order and speed control are vital. She pairs well with high-damage nukers that benefit from the increased speed and turn cycling she facilitates. However, due to her relatively low durability and lack of cleanse or crowd control beyond speed debuffs, she requires good rune optimization focused on speed and survivability. Overall, Kroa is best used in fast-paced, aggressive comps that rely on quick bursts of offense and sustained team buffs.

Strength and Weakness

Strength: Kroa’s main strength lies in her exceptionally high base Speed, which is among the fastest for natural 3★ monsters, allowing her to consistently take the first turns in battle. This speed advantage enables her to effectively manipulate the turn order by filling allies’ Attack Bars and reducing enemies’ bars with her skills.

Weakness: Kroa’s primary weakness is her relatively low durability—she has moderate HP and defense stats, making her somewhat squishy and vulnerable to burst damage, especially in tougher PvP or PvE content. She also lacks strong crowd control beyond her speed and ATB reduction debuffs, meaning she can’t cleanse harmful effects or provide stuns or freezes like other support monsters.

Synergy

Kroa (Dark Harg) synergizes best with high-damage nukers and speed-dependent teams that benefit from her Attack Bar boosts, Speed buffs, and healing. She pairs particularly well with units like Lushen, Galleon, or Theomars, who can capitalize on the extra turns and increased Speed to unleash powerful combos quickly. Speed leaders like Leo or Bernard complement her by further increasing the team’s turn advantage, allowing Kroa to cycle her buffs and heals more frequently.

In siege or RTA, she works effectively alongside units that rely on controlling turn order, helping to disrupt enemy plays while enhancing your team’s offense and survivability. However, because Kroa doesn’t provide cleanse or hard crowd control, pairing her with monsters who can fill those roles—such as Fran or Praha—can balance the team’s utility and increase overall effectiveness.
