Embed Spell Focus

You are so attuned to the magic that flows through all things that you can fuse a spellcasting focus to yourself, among other things.  Once per hour, you can use powerful enchantment magic to cast a spellcasting focus of any kind or a magic item into your hide, granting you the following benefits. 

• You can concentrate on two spells at once, though while you do so and if both spells are 6th level or higher, you have disadvantage on saving throws against losing concentration on them.
• You are considered attuned to all of the magic items casted to you. While you cannot use them as standard weapons (a magical quarterstaff can't be used as a weapon, for example), you can use all of their charged abilities and when those magic items recharge their charges, roll a 1d4 - 1 and add the result to the amount of regained charges. 
• Once per day, if you have 8 or more spellcasting focuses or magic items infused with your being, you can make yourself automatically succeed on saving throws against spells of 2nd level or lower and have advantage on saving throws against all other spells and magical effects for 1 hour.

You can have no more than 5 + your Constitution modifier spellcasting focuses or magic items infused with your being, though that number varies based on the overall size of the magic items you wish to fuse.
