Purple Pears. Each tree has 3d6 ripe pears hanging from its branches, most of them within reach. Any creature that eats more than half of a purple pear gains the benefit of a special charm (see “Supernatural Gifts” in the Dungeon Master’s Guide). Determine the charm randomly by rolling a d20 and consulting the Purple Pear Charms table. This charm must vanish from a creature before it can gain any more charms by eating purple pears. A creature that eats three or more purple pears within 1 hour is poisoned for 24 hours thereafter and suffers painful cramps until the condition ends.

Mantle of Spell Resistance
Wondrous item, rare (requires attunement)
You have advantage on saving throws against spells while you wear this cloak.
Chardalyn Staff of Charming
Staff, rare (requires attunement by a bard, cleric, druid, sorcerer, warlock, or wizard)
While holding this staff, you can use an action to expend 1 of its 10 charges to cast charm person, command, or comprehend languages from it using your spell save DC. The staff can also be used as a magic quarterstaff.
If you are holding the staff and fail a saving throw against an enchantment spell that targets only you, you can turn your failed save into a successful one. You can’t use this property of the staff again until the next dawn. If you succeed on a save against an enchantment spell that targets only you, with or without the staff’s intervention, you can use your reaction to expend 1 charge from the staff and turn the spell back on its caster as if you had cast the spell.
The staff regains 1d8 + 2 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the staff becomes a nonmagical quarterstaff.
