Celestial Conqueror - Spirit armor

Name: Celestial Conqueror
Rank: Legendary
Type: Celestial Armor
Description:

While the images armor is white, Nakiya's is a very deep purple, almost black with golden patterns decorating the armor. Two pauldrons sit on her hips held together by leather strappings. These strappings also hold a dark loin cloth that carries the same design as her armor. The chest plate has a neck guard that comes up just under Nakiya's chin. The chest plate is then connected to two shoulder bells, and each arm is covered by gauntlets. All of this armor is held together over-top a deep crimson leather coat that hugs Nakiya's features.

This armor has the ability to absorb her dark keys through a rectangular box on the chest plate. When a key has been summoned, she herself is then counted as whatever Celestial Spirit is within the armor. This means that she herself counts towards the amount of Celestial Spirits she can have on the field at a time. She respects all of the spirits strengths, weaknesses, cooldown and abilities. However, when a spirit is absorbed into the armor, their spells DO cost her MP, unlike if she simply summoned the spirit, then their spells would not cost her anything.
Strengths:

• This armour absorbs the power of any dark or corrupted key into a piece in the chest plate. Once absorbed, this armour takes on all of the abilities of the key and allows Nakiya to use them as if they were her own.
  
• Nakiya is granted a higher endurance when wearing the armour
  
• When a spirit is absorbed by the armour, it cannot be dismissed by anyone but the wearer or if the duration is finished.
  

Weaknesses:

• Can only absorb dark or corrupted keys, cannot absorb light keys
  
• When a key is absorbed, that spirit cannot be summoned. Nakiya takes on the Spirits duration and cooldown as if they were her own. This means, once the duration is up, the Celestial Spirit goes on cooldown.
  
• Once a spirit is absorbed, the armor is treated as a ‘summon’, meaning that she is limiting how many spirits she can have by her side while taking advantage of the armor.
  
• Gains all of the weaknesses of the absorbed spirit.
  

Abilities:

• The armour absorbs one of Nakiya’s dark Celestial Keys, drawing the power from the key and allowing Nakiya to harness their powers for themselves. For example, if Nakiya were to absorb Vulpeca’s key, she would gain the ability to use Fire magic, while if she were to absorb Wrath’s key, the would gain shadow magic. While the key is absorbed by the armour, the Celestial spirit cannot be summoned. The armor and the key that has been absorbed share the same durations and cooldowns, as well as the same strengths and weaknesses.
  
• This armour can not only resist B rank damage, it also allows Nakiya to take an additional 2 hits of Rank damage before breaking.
  

Seems simple enough; equip the spirit rather than summon it. No issues here.
