Blue Crystal
The Blue Crystal is a foe in Epic Battle Fantasy 4 and 5. In EBF4, it is primarily summoned as a helper for Light Godcat/The Creator and Dark Natalie; in EBF5, it appears in the Data Bunker as one of the Classic foes.
Appearance
The Blue Crystal is - as the name suggests - a large blue crystal implied to be made of condensed Ice magic. It is vaguely rhombus-shaped, with an elaborate white sigil on its front that resembles an eight-limbed snowflake. Four small crystals surround the main crystal.
Overview
The Blue Crystal isn't especially threatening on its own, but it's an effective offensive support unit for more dangerous enemies. It mainly uses single-target Ice attacks, either physical moves with a low elemental degree or pure elemental magic attacks with a chance to Freeze their targets. It can also buff the defenses of itself and its allies or cast Cloudburst to make everyone Wet; this allows it to hit the players harder and with a higher Freeze chance.
Syphon and Berserk are both effective at preventing the Blue Crystal from supporting its allies. The former limits it to a relatively unimpressive physical attack, while the latter forces it to spam a pure Ice spell that can be dampened with the appropriate resistances.
The Blue Crystal always absorbs Ice and Water while being severely weak to Fire. It's also immune to Freeze and Poison.
Epic Battle Fantasy 4
The Blue Crystal has four Ice-based attacks to choose from, two physical and two magical. The latter are the main threat, since they have significant Freeze chances; Blizzard has better Accuracy and infliction chance, but Energy Shot can potentially immobilize the target for two turns instead of one. In contrast, the Crystal's physical attacks have no special attributes; however, their low elemental degree gives it an option to damage players with strong Ice resistance.
The Blue Crystal also has some support abilities to work with. It can give the entire enemy wave a decent buff to their Defence and Magic Defence; on higher difficulty levels, the buff becomes even stronger. Additionally, it can cast Cloudburst to Wet everyone on the battlefield, allowing its Ice attacks to hit harder while boosting the Freeze chance on its spells. Becoming Wet itself also dampens its worst elemental weakness while amplifying its Thunder weakness.
The Blue Crystal's resistances are relatively limited; it absorbs Ice and Water, has an immunity to Freeze and Poison, and resists Burn. On the other hand, it's weak to Bomb, Earth, Thunder, and especially Fire. "More Foe Resistance" gives it Wind and Holy absorptions along with resistances to Stun, Syphon, and Stagger.
Epic Battle Fantasy 5
The Blue Crystal has two part-Ice physical attacks that can inflict Syphon, but its main offensive threat comes from its spells. Their decent Base Power is supplemented by a high Magic Attack, and they have fair chances to Freeze their targets; Deep Freeze is stronger and has a better infliction chance, but Energy Shot applies more Freeze stacks. The Crystal can further enhance its threat level by using Cloudburst to Wet the players; this can also Wet itself, reducing one of its elemental weaknesses. Additionally, it can buff the defenses of itself and its allies; unlike most buffs, this will stack with any stat changes instead of replacing them. As a Classic foe, it ignores Lovable and can't be afflicted with Invisible or Enchanted.
On higher difficulty levels, the Blue Crystal's buff is slightly stronger and its status infliction skyrockets; notably, Deep Freeze has a 200% Freeze chance. As such, Freeze immunity is paramount if you can't disable or kill the Crystal immediately.
The Blue Crystal absorbs Ice and Water and is immune to Holy, but has severe weaknesses to Fire and Dark. Its status resistances include immunity to Chill, Freeze, Poison, and Virus, a strong resistance to Stun, and a moderate resistance to all debuffs except HP. With "More Foe Resistance" enabled, its Fire weakness is lessened and it becomes immune to Stagger, Weaken, Tired, Doom, Instant Death, and Magic Attack debuffs.

Battle Logic
The following describes general logic of the enemy and attack patterns, with chances of each attack to be used. Conditions are listed from highest to lowest priority unless specified otherwise.
Epic Battle Fantasy 4
- Berserked → Energy Shot;
- Syphoned → Grind;
- Otherwise → Quad Prick (1/6), Grind (1/6), Blizzard (1/6), Energy Shot (1/6), Cloudburst (1/6), Buff (1/6).
Epic Battle Fantasy 5
Action
- If Syphoned → Grind;
- If Berserked → Energy Shot;
- Otherwise → Quad Prick (1/6), Grind (1/6), Deep Freeze (1/6), Energy Shot (1/6), Cloudburst (1/6), Buff (1/6).
Counter (only if Counter-Attacking Foes is enabled)
- 25% and not Syphoned → Deep Freeze.
*Unlike most other foes, the Blue Crystal's counter targets randomly, instead of always targeting its last attacker.
Additionally, like all the Classic foes, the Blue Crystal ignores the Lovable status on players.
Summon
Epic Battle Fantasy 5
In EBF5, the Blue Crystal can be captured and used as a summon; it can also be called between turns by the Alt Cold Steel. It uses Quad Prick on a single target, dealing minor physical Ice damage with an enormous chance to Freeze them for five turns.
