Assessment

Strengths & weaknesses

Fredrinn boasts exceptional durability, allowing him to withstand significant incoming damage and remain a persistent threat in teamfights. His unique passive, Crystalline Armor, allows him to convert damage taken into HP, providing incredible sustain as long as he continues to deal damage. This makes him very hard to take down in prolonged engagements. Furthermore, his kit provides a balanced mix of physical and magical offense, ensuring he contributes meaningful damage regardless of enemy defenses, while also offering crowd control through slows, airborne effects, and taunts.

However, Fredrinn's effectiveness is tied to his Combo Points, which require him to consistently land skills on non-minion enemies. If he misses his abilities or is unable to engage, his damage output and survivability suffer significantly. His moderate difficulty means that proper management of his passive and skill rotations is crucial, requiring players to be mindful of their positioning and timing. He can also be vulnerable to being kited if his dash (Brave Assault) is on cooldown, making it difficult for him to stick to high-priority targets.

Kit

Skills

Passive

Crystalline Armor

Fredrinn gains 1 Combo Point that lasts 5s each time his skill hits a non-minion enemy, up to 4 Combo Points. His Ultimates cost different numbers of Combo Points.
Fredrinn stores 100% of the damage he receives as Crystal Energy, which decays after 5s at a rate of 10% Max HP per second.
Fredrinn can convert the stored Crystal Energy into HP by 20% of his damage dealt (10% for damage dealt to minions). Gaining a Combo Point resets the decaying timer.

He can also restore HP by his damage dealt.

Skill 1

Piercing Strike

Fredrinn thrusts his sword in the target direction, dealing 125+7% Total HP (+120% Extra Physical Attack) Physical Damage to enemies hit and slowing them by 30% for 2s. His next Basic Attack gains extra attack range and deals 85 (+100% Total Physical Attack) Physical Damage.
This skill deals 150% damage to non-hero enemies.

  • 125 + 7% Max HP Physical
  • 120% Extra Physical Attack Physical
  • 85 + 100% Total Physical Attack Physical

Use this skill to deal damage and clear lanes, while gaining combo points!

Skill 2

Brave Assault

Fredrinn dashes in the target direction, dealing 140 (+80% Extra Physical Attack) Physical Damage to the first non-minion enemy hit. His next Basic Attack knocks the target airborne for 0.3s.

  • 140 + 80% Extra Physical Attack Physical

Use this skill to approach enemies or start combos. Cast it followed by enhanced Basic Attacks to control enemies.

Ultimate

Energy Eruption

Fredrinn deals 210 (+100% Extra Physical Attack) Physical Damage to nearby enemies and taunts them for 1s. Hitting a non-minion enemy grants Fredrinn 15 Physical & Magic Defense for 3s and reduces the cooldowns of Piercing Strike and Brave Assault by 75%.
This skill costs 1 Combo Point.

  • 210 + 100% Extra Physical Attack Physical

As the primary damage source, this skill can deal massive damage to enemies in teamfights.

Crystalline Armor (Passive)

Fredrinn's passive is the core of his sustained fighting style. Each time his skill hits a non-minion enemy, he gains 1 Combo Point, up to 4. These Combo Points are essential for his Ultimate. More importantly, he stores 100% of the damage he receives as Crystal Energy, which he can then convert into HP by 20% of his damage dealt (10% for minions). This means Fredrinn heals by dealing damage, making offensive items also contribute to his survivability. The key is to keep dealing damage after taking hits to maximize his healing.

Piercing Strike (Skill 1)

Fredrinn thrusts his sword, dealing damage and slowing enemies. This skill deals 125 flat + 7% scaling (Max HP, Physical) and 120% scaling (Extra Physical Attack, Physical) to enemies hit. This means the damage scales with both his maximum HP, making tanky builds effective, and his extra physical attack. After casting, his next Basic Attack gains extra range and deals 85 flat + 100% scaling (Total Physical Attack, Physical). Use Piercing Strike to poke enemies, slow their advance, clear minion waves efficiently (it deals 150% damage to non-hero enemies), and generate Combo Points. The enhanced Basic Attack provides additional burst and reach.

Brave Assault (Skill 2)

This is Fredrinn's primary engagement and mobility tool. He dashes in the target direction, dealing 140 flat + 80% scaling (Extra Physical Attack, Physical) to the first non-minion enemy hit. The damage scales well with extra physical attack, making it a decent source of burst. His next Basic Attack after this skill will knock the target airborne for 0.3s. Use Brave Assault to close gaps, initiate fights, or reposition. The airborne effect from the enhanced Basic Attack is crucial for setting up further crowd control or allowing allies to follow up.

Energy Eruption (Ultimate)

Fredrinn's Ultimate is a powerful area-of-effect ability that costs 1 Combo Point. He deals 210 flat + 100% scaling (Extra Physical Attack, Physical) to nearby enemies and taunts them for 1s. This scaling ensures it hits hard with physical attack items. Hitting a non-minion enemy also grants Fredrinn 15 Physical & Magic Defense for 3s and, critically, reduces the cooldowns of Piercing Strike and Brave Assault by 75%. This makes Energy Eruption a central part of his damage rotation and survivability. Cast it in the middle of enemy formations to maximize damage, taunt key targets, and reset your other abilities to continue your assault.

Thunder Belt

Unique Passive - Thunderbolt: After casting a skill, the next Basic Attack within 3s deals 50 plus 5% of the hero's extra HP as extra True Damage to the target and enemies around them and slows them by 40%-80% (scales with the hero's extra HP) for 1s (1.5s cooldown).

Unique Passive - Recovery: Regenerates 2.5% Max HP per second (reduced to 0.5% Max HP per second over 5s after taking damage).

Fredrinn's recommended build focuses on enhancing his durability and sustained damage, synergizing with his unique healing mechanics.

  • Warrior Boots: These provide essential movement speed and physical defense. The unique passive, Valor, grants additional physical defense when taking physical damage, further boosting Fredrinn's tankiness in skirmishes.
  • Bloodlust Axe: This item is crucial for Fredrinn. While it doesn't have a unique passive listed, its core stats provide Spell Vamp, which directly contributes to Fredrinn's healing from his Crystalline Armor passive. The more damage he deals with skills, the more he heals, making this a cornerstone for his sustain.
  • Cursed Helmet: This item significantly boosts Fredrinn's HP and provides a unique passive, Burning Soul. This passive deals Magic Damage equal to 0.6% of his Max HP per second to nearby enemies, which is increased against creeps and minions. This synergizes perfectly with Fredrinn's high HP pool and helps him clear waves and jungle camps faster, while also adding consistent damage in fights.
  • Thunder Belt: This item provides a good mix of HP, physical defense, and cooldown reduction. Its unique passive, Thunderbolt, enhances Fredrinn's next Basic Attack after using a skill, dealing True Damage based on his extra HP and slowing enemies. This is perfect for Fredrinn, who frequently weaves Basic Attacks between skills, adding burst and crowd control to his kit, especially given his high HP.
  • Oracle: This item is a defensive powerhouse for Fredrinn. It provides magic defense, HP, and cooldown reduction. Its unique passive, Bless, increases received Shield and HP Regen effects by 30%. This directly amplifies the healing from his Crystalline Armor and any other HP regeneration, making him even harder to kill.
  • Guardian Helmet: As a late-game defensive item, Guardian Helmet offers a massive boost to HP and provides strong HP regeneration. Its unique passive, Recovery, regenerates 2.5% Max HP per second when out of combat, and even 0.5% when taking damage. Combined with Oracle, this provides incredible sustain, allowing Fredrinn to quickly recover between engagements without needing to recall.

Coaching

Playstyle tips

Fredrinn's playstyle revolves around aggressive engagements and sustained fighting. In the early game, use Piercing Strike to clear minion waves and poke enemies, generating Combo Points. Look for opportunities to engage with Brave Assault, using its enhanced Basic Attack to knock up targets, followed by Piercing Strike for additional damage and slow. Always be mindful of your Crystalline Armor passive; try to deal damage after taking hits to convert Crystal Energy into HP and stay healthy.

During teamfights, position yourself to absorb damage for your team while dishing out your own. Initiate with Brave Assault to dive into the enemy backline or catch out a priority target. Follow up with your enhanced Basic Attack for the airborne effect. Use Piercing Strike to keep enemies slowed and generate more Combo Points. Once you have a Combo Point, unleash Energy Eruption in the thick of the enemy team to deal significant damage, taunt key threats, gain extra defenses, and most importantly, reset the cooldowns of your other skills. This allows you to chain abilities together, maintaining pressure and crowd control. Continuously weave Basic Attacks between skills to maximize damage and trigger item passives like Thunder Belt.

Matchups

Counters

Understanding matchups helps Fredrinn excel in various team compositions.

  • Karina: The grounding indicates that Karina can be a good ally for Fredrinn. Her burst damage can complement Fredrinn's sustained fighting, helping to secure kills on targets he has engaged and locked down.
  • Khaleed: Fredrinn can be an effective counter against Khaleed. Fredrinn's crowd control and sustained damage can interrupt Khaleed's channeled abilities and out-trade him in extended fights.
  • Karrie: Fredrinn can be countered by Karrie. Her true damage output can bypass Fredrinn's high defenses, making her a significant threat that can quickly whittle down his HP despite his sustain.

In practice

A practical scenario

Imagine you're in a teamfight and spot an enemy marksman slightly out of position. You can initiate by using Brave Assault to dash onto them, immediately following up with your enhanced Basic Attack to knock them airborne. As they land, cast Piercing Strike to deal damage and apply a slow, then follow with another enhanced Basic Attack. By now, you should have at least one Combo Point. Activate your Ultimate, Energy Eruption, to deal area damage, taunt the marksman (and any nearby enemies), gain bonus defenses, and crucially, reset the cooldowns of Brave Assault and Piercing Strike. This allows you to immediately cast Brave Assault again to reposition or chase, and then Piercing Strike for continued damage and slow, keeping the enemy locked down and taking sustained damage.

Summary

Key takeaways

  1. Manage your Crystalline Armor passive by consistently dealing damage after taking hits to convert Crystal Energy into vital HP.
  2. Prioritize Bloodlust Axe early in your build to significantly enhance your skill-based healing and sustain in prolonged engagements.
  3. Initiate fights strategically with Brave Assault, using its dash and enhanced Basic Attack for crucial crowd control and engagement.
  4. Time Energy Eruption to hit multiple enemies, gaining maximum value from its damage, taunt, defensive buff, and essential cooldown resets for your other skills.
