Hero Guide

[The Serpent Sin of Envy] Holy Knight Diane or more commonly known as Blue Giant Diane is a hero you can get for free by clearing Chapter 4 of the Main Story. She plays a large role in getting you through roadblocks of the story mode and sub-quests, as well as climb ranks in PVP.

Using her skill’s Rupture effect, Blue Giant Diane specifically counters buff-centered teams, inflicting 2x damage against buffed enemies. This is especially true when fighting against Mono-Red teams with Red Arthur and teams that use Amplify effects.

She provides good damage and utility through attack disable. As the battle progresses further leading to more turns, Blue Giant Diane’s unique ability will gradually increase her attack for up to 30%, making her extremely powerful in longer fights.


Pros

  • High attack stat
  • Strong AoE ultimate with up to 900% of her attack value as damage
  • Strong counter against Mono-Red teams which are very relevant in PVP

Cons

  • Hard to upgrade her Ultimate (rarely available on banners and events) and has to be purchased in the coin shop to quickly increase her ult level
  • Low base Defense and Resistance
  • Diminishing use in PVE as you progress further


Skill Review

Rush Rock - Her attack disabling proves very useful when combatting bosses or when in PvP. This skill also counters heroes who solely rely on attack-type skills (Red Howzer, Red Escanor, etc.).

Ground Gladius - Doubles the damage when used against buffed heroes. At max rank, she can deal 500% of her attack on all enemies. This skill, however, does mediocre damage against an unbuffed hero. The timing and usage of this skill are crucial.

Ultimate: Mother Earth Catastrophe - With the help of her Sacred Treasure “War Hammer Gideon”, she inflicts up to 900% attack on all enemies using brute force. This does not have an additional skill effect like most Ultimates (ex. Rupture, Shatter) but the high damage multiplier is sufficient enough to crush her enemies.

Unique: Giant's Will - This unique ability gradually increases Blue Giant Diane’s attack by up to 30%, achieving the max value on the 5th turn. This perfectly sets up a combo with her Ultimate, adding more damage to an already powerful skill.


Usage

Equipment Set - Onslaught (Attack) or Life (HP) / Iron Wall (Defense).

Substats are as follows:
Bracer/Ring - Attack
Necklace/Earring - Defense
Belt/Rune - HP

PVP - In the early phase of progression, Blue Giant Diane will be a huge help in increasing your PVP ranks from Bronze to Platinum. Moreover, she is a Strong counter to Mono-Red and buff-centered teams which are prevalent in Master Tier and above.

Early Game PVE - As part of the reward for clearing Chapter 4, Blue Giant Diane provides the much-needed support to clear hard stages and major roadblocks of PVE game modes. Until you can build a more efficient PVE team for farming (Red Howzer teams), Blue Giant Diane and Blue King remain to be an effective choice for budget-friendly teams.

Story Mode boss battles - There are storyline battles where you are required to use Diane. Blue Giant Diane does the job extremely well compared to other versions of Diane (Ex. Stage 1 of Ep.72 Hendrickson Boss).

Early Game Red Demon - After unlocking the Red Demon at Chapter 5 and having a limited pool of heroes to select, Blue Giant Diane is one of the most favorable choices for starters alongside Blue King and Green Gustav.

Training Grotto - Blue Giant Diane is a good pick against the Level 3 Red Amber Frenzied Giant Explosive Giant. She is also used to counter Strength-type (Red) Illusion Ambers. Check out Training Grotto Level 3 teams for a full list of recommended heroes on each boss battle.

Story

Many years ago, Diane left the Giant's Clan due to her hatred for fighting. After her departure, she formed two rock-like golems to accompany her, despite either of them being unable to talk. She was always alone playing with them as there were no other living beings who would accept her.

At one time, however; Diane found an injured King lying unconscious on a riverbank and nursed the fairy back to health. King, who had taken a hard blow to his head, had lost all memories of his past and in his gratitude spent the next five hundred years playing with and protecting Diane. Diane later met an old man, a human, who offered Diane and King some food despite them being Fairy and a Giant. King was wary with the old man and told Diane to be careful around humans. Due to unknown reasons, Diane ended up getting a fever, in which King panicked due to Fairies never having fevers and went out to get herbs. However, Diane stopped him, telling him to not ever leave her side since she didn't want to be alone anymore. The old man who gave them food found them, and concocted a herbal medicine for Diane's fever, eventually curing her of her ailment. As soon as Diane got better, King and Diane ended up playing tag with each other, as King told her that if she caught him, he will grant her a wish.

Diane took it seriously and caught King, but ended up getting her clothes ripped off in the fray, leaving her entirely naked, much to King's dismay. King ends up making her new clothes and the two went to visit the old man hunter's place, only to find more houses had sprung up around there, and that the man they believed was the hunter they had met was actually the late hunter's grandson. After leaving the forest, King told Diane about marriage between two humans who love each other. Diane asked if King loves her, which he flushed to, but agreed. Diane thus chose to use King's promise to make him always love her. He agreed wholeheartedly. Later that night, King ended up remembering who he is through various flashbacks in his dreams and found out that the village close by was on fire. King told Diane to stay back as he went to the town, promising to come back. Diane waited in tears, hoping for King to return, only to find King return and strike her with a flower to her spine to erase her memories of him. Diane eventually awoke from her slumber without any memories, but curiously picked up King's flower and walked outside. She rejoins the Giant's Clan afterward.
