You have resistance to fire damage while you hold this staff.

The staff has 10 charges. While holding it, you can use an action to expend 1 or more of its charges to cast one of the following spells from it, using your spell save DC: burning hands (1 charge), fireball (3 charges), or wall of fire (4 charges).

The staff regains 1d6 + 4 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the staff blackens, crumbles into cinders, and is destroyed.

While holding this staff, you can use your reaction to absorb a spell that is targeting only you and not with an area of effect. The absorbed spell's effect is canceled, and the spell's energy -- not the spell itself -- is stored in the staff. The energy has the same level as the spell when it was cast. The staff  can absorb and store up to 50 levels of energy over the course of its existence. Once the staff absorbs 50 levels of energy, it can't absorb more. If you are targeted by a spell that the staff can't store, the staff has no effect on that spell.

When you become attuned to the staff, you know how many levels of energy the staff has absorbed over the course of its existence, and how many levels of spell energy it currently has stored.

If you are a spellcaster holding the staff, you can convert energy stored in it into spell slots to cast spells you have prepared or know. You can create spell slots only of a level equal to or lower than your own spell slots, up to a maximum of 5th level. You use the stored levels in place of your slots, but otherwise cast the spell as normal. For example, you can use 3 levels stored in the staff as a 3rd-level spell slot.

A newly found rod has 1d10 levels of spell energy stored in it already. A staff that can no longer absorb spell energy and has no energy remaining becomes nonmagical.
