The Wand of Fireballs (as well as several other magic items that have charges1) has a chance of the item being lost forever when the last charge is expended:
If you expend the wand's last charge, roll a d20. On a 1, the wand crumbles into ashes and is destroyed.
I am looking for ways to influence this roll to lower (or remove completely) the chance that the wand will be destroyed. Unfortunately, so far I have been unsuccessful (barring the usual "Wish can do anything").
Things like Inspiration, the Divination Wizard's Portent and the Lucky feat all specificy which rolls they apply to so can't help with this particular d20 roll.
Are there any class features/abilities/spells/anything at all that are able to influence this d20 roll to avoid the destruction of the wand of fireballs?
Any official source will do, including UA as well.
