Requires Attunement

While wearing these bracers, you gain a +2 bonus to AC if you are wearing no armor and using no shield.

This item has been meticulously trimmed and tended to in such a way that it appears to be a smaller version of one of the immense jungle trees in Chult. The staff’s creator even went so far as to create a small diorama of what looks like a tiny village in the upper reaches of the staff’s branches—complete with tiny, string bridges connecting tiny, straw houses.

This staff can be wielded as a magic quarterstaff that grants a +2 bonus to attack and damage rolls made with it. While holding it, you have a +2 bonus to spell attack rolls.
The staff has 10 charges for the following properties. It regains 1d6+4 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the staff loses its properties and becomes a nonmagical quarterstaff.

Spells.
You can use an action to expend 1 or more of the staff's charges to cast one of the following spells from it, using your spell save DC: animal friendship (1 charge), awaken (5 charges), barkskin (2 charges), locate animals or plants (2 charges), speak with animals (1 charge), speak with plants (3 charges), or wall of thorns (6 charges).

You can also use an action to cast the pass without trace spell from the staff without using any charges.

Tree Form.
You can use an action to plant one end of the staff in fertile earth and expend 1 charge to transform the staff into a healthy tree. The tree is 60 feet tall and has a 5-foot-diameter trunk, and its branches at the top spread out in a 20-foot radius. The tree appears ordinary but radiates a faint aura of transmutation magic if targeted by detect magic. While touching the tree and using another action to speak its command word, you return the staff to its normal form. Any creature in the tree falls when it reverts to a staff.

Crafted from the black, chitinous hide of a giant spider with goldleaf etchings of centaur warriors, the quiver gives you advantage on social interaction checks to improve the attitude of centaurs. This item functions as a quiver of Ehlonna

The emerald is an emerald of the war mage (functions as a ruby of the war mage)
The altar is inlaid with ten additional ordinary emeralds—each worth 50 gp.

Wondrous item, common (requires attunement by a spellcaster)

Etched with eldritch runes, this 1-inch-diameter ruby allows you to use a simple or martial weapon as a spellcasting focus for your spells. For this property to work, you must attach the ruby to the weapon by pressing the ruby against it for at least 10 minutes. Thereafter, the ruby can't be removed unless you detach it as an action or the weapon is destroyed. Not even an Antimagic Field causes it to fall off. The ruby does fall off the weapon if your attunement to the ruby ends.

Constructed of flat, smooth, and overlapping river stones, this set of scale mail is surprisingly light and mobile. While wearing the armor, you need half the water normally required to stave off exhaustion. This item functions as mariner’s armor (scale mail)

The jewels in the insignia of the Cult of the Dragon flare with purple light when you enter combat, empowering your natural fists or natural weapons.

While wearing the insignia you gain a +1 bonus to the attack rolls and the damage rolls you make with unarmed strikes and natural weapons. Such attacks are considered to be magical.
