Medal
A Medal (メダル Medaru) is a character-based object holding skills and Special Attacks you can utilize in Kingdom Hearts Unchained χ / Union χ.
Attack Medals are equipped to your Keyblade deck, allowing you to perform more powerful attacks than your Keyblade alone can inflict. Players can equip a maximum of 5 Medals depending on the strength of their Keyblade, plus one Friend Medal.
Support Medals are used to improve your Attack Medals, either by leveling up, evolving, or adding skills.
Buff Medals are used to greatly increase your damage output; Debuff Medals are used to reduce your enemies' defense. The buffs and debuffs can be stacked up to 3 times each.
- Strength can be raised by up to 3 tiers.
- Defense can be lowered by up to 3 tiers.
There are separate strength and defense parameters for individual attributes as well. So you can also raise/lower attribute-based strength/defense by up to 3 tiers in addition to the regular strength/defense buffs and debuffs listed above.
Special Attacks
A Special Attack (アビリティ Abiriti, lit. "Ability") is an attack attached to each Medal that requires a certain number of gauges to use. When the player has enough gauges, these Special Attacks can be unleashed by swiping the Medal toward the center of the screen. Special Attacks can be single target, all target, or random target, referring to the number of enemies struck by the attack. Some rare Medals might have an all-target Special Attack which is normally single target; these Special Attacks will have a higher gauge cost to activate.
- For Medals that are rarity 3★ or higher, if you combine two of the same Medal of the same rarity, you can increase the power of its Special Attack. Each time you do this, a dot ○ will become filled in ●.
- The number of dots that you can fill in depends on the Medal's rarity. A 3★ Medal can be strengthened to 1 dot ●, a 4★ Medal 2 dots ●●, a 5★ Medal 3 dots ●●●, and a 6★ Medal can be strengthened to a total of 5 dots ●●●●●.
Special Attack Bonus
_KHUX.png)
The Special Attack Bonus (ギルト Giruto, lit. "Guilt") is a trait found on 6★ Medals which have been strengthened with the Power Bangle, which is obtained in Quest 200 (English version) or Quest 350 (Japanese version). A 6★ Medal's Special Attack Bonus can be unlocked by strengthening it one more time after the 5 dots have been filled in. The Special Attack Bonus is a damage bonus added on top of the damage multipliers the player earns by strengthening their Medal.
Different Medals have different Special Attack Bonus Tiers, which determine the range of the bonus received. When a Special Attack Bonus is applied, a value in that range is randomly chosen. By strengthening the medal with Mickey and Broom Servants or an additional copy of that 6★ Medal, the Special Attack Bonus will be recalculated. If the new value is higher than the previous value, it will be kept, otherwise the previous value will be retained. Common Medals will have Level 1 Bonus, Normal Medals will have Level 2, Rare Medals will have Level 3, and Super Rare Medals will have either Level 3, 4 or 5.

Nova
Nova (バースト Bāsuto, lit. "Burst") is a type of attack that deals massive damage with no attributes to all targets but can only be used once per quest or Raid Boss battle. Nova can be used once the player has unlocked the Special Attack Bonus of at least one Medal. It can be activated by pressing the button on the top right of the screen at any point during the player's turn before the last Medal is played. The higher the Nova level, the more damage it deals.
Skills
A Skill (スキル Sukiru) is a special passive ability that rarely appears on Medals drawn from the Shop deals, or which are added to Medals by fusing with a Scrooge Medal. Scrooge Medals can be found in Coliseum Boards, Premium Boards, or rarely as quest objectives (usually for Event Quests).
Skills can be transferred from one Medal to another through fusing. The Medal in the first slot has a chance of passing its skill on to the base Medal, starting at 20% at skill level 1 and increasing as the skill levels up to 100% at max level; Scrooge Medals will always have their skill level at maximum, barring a bug. Pressing the "Overwrite Skill" button in the fusing process turns this feature off (it is on by default).
To level up a skill, simply use the Medal as you fight enemies. Skills have a chance of activating when a Medal is used, or when a special condition is met. As a skill levels up, it has a higher chance of being triggered.
