Amulet of the Fallen Champion

''The power coursing through you is palpable. The attunement completed, you feel nigh unstoppable now, you feel ready to take on the world, your body able to respond with lightning ferocity. And then you see the flood of memories that overwhelm you and bring you to your knees, drawing the life from your lungs and a sharp pain into your skull. Nobody who has ever worn this has died a peaceful death. Their days were numbered.''

Wonderous, Item Requires Attunement.
This onyx and diamond necklace radiates with power. It grants advantage on Strength, Dexterity, and Constitution saving throws, +1 to attack and damage rolls, critcal threat range +1. Your high jump increases by 5ft, and your long jump increases by 10ft. You count as one size larger for the purposes of determining how much you can lift, carry, or drag. You gain a swim speed of 30ft and a climb speed of 15ft. You can read, write, and speak Elvish, Dwarvish, Orcish, Draconic, and Primordial while attuned to the amulet.

The amulet can store up to 5 levels of spells.

The amulet has 4 charges and regains them all at dawn. You can expend a charge to turn a missed attack roll into a hit, or a hit against you into a miss as long as it isn't a critical hit. You can expend two charges to succeed on a saving throw that you have failed.
