Eldritch Armory

Dedicating your life to the blade, your patron has granted you a unique benefit, allowing you to hold more weapons that would qualify for Pact of the Blade.

You can store a number of weapons in the same extradimensional space as your pact weapon equal to half your proficiency bonus (Rounding Up). In addition, if a pact weapon would require attunement, it counts as attuned as long as you are wielding it.

As a bonus action you may switch between another bonded pact weapon, when doing so the previously wielded pact weapon returns to the extradimensional space and the effects from being attuned to that weapon end.
