Spear of Mohan

In a moment of profound connection, Sarthak recognized the purity of Mohan's heart and bestowed upon him a gift of great power – a magical bronze spear. Crafted by the dragon's own breath and infused with the essence of ancient magic, the spear gleamed with an ethereal light, its surface adorned with intricate runes that pulsed with otherworldly energy.

The quarter staff can absorb wealth and magical items by meditating while holding both for a minute, granting the user special benefits depending on the amount of gold or the rarity of the magic item:   100 gold or Common: The wielder gains 5 temporary hit points.   500 gold or Uncommon: The wielder gains 10 temporary hit points.   5000 gold or Rare: The wielder's maximum hit points permanently increase by 2. They also gain advantage on ability checks and attacks rolls until the next long rest.   50,000 gold or Very rare: The wielder's maximum hit points permanently increase by 5. They also gain advantage on ability checks, saving throws, and attacks rolls until the next long rest.   250,000 gold or Legendary: One of the wielder's ability scores increases by 2, as well as their maximum score. Particularly powerful items can bestow additional benefits.   Artifact: This weapon cannot absorb Artifacts.
After this process, the wealth/item is absorbed by magical means into the quarter staff.   A creature can't benefit from this item a second time until the next long rest. Moreover, if the quarter staff is used again in the next 24 hours there is a cumulative 20% chance that it will break.   If the benefit conferred by the quarterstaff is a spell with a saving throw, the DC is either the user's normal spell DC, or if they are not normally a spellcaster, 8 + proficiency bonus + bonus for the highest of their Charisma, Wisdom, or Intelligence skills.
