The 7 Rings of the Dwarf Elders

The 6 dwarf Elders and the King of Citadel Adbar are wearing 7 rings with different powers accentuating their status and roles.

• Ring of the King: Ring of Regeneration - While wearing this ring, you regain 1d6 hit points every 10 minutes, provided that you have at least 1 hit point. If you lose a body part, the ring causes the missing part to regrow and return to full functionality after 1d6 + 1 days if you have at least 1 hit point the whole time.
• Ring of Grag Hamcrusher - The Eldar of Trust: Ring of Mind Shielding - While wearing this ring, you are immune to magic that allows other creatures to read your thoughts, determine whether you are lying, know your alignment, or know your creature type. Creatures can telepathically communicate with you only if you allow it. You can use an action to cause the ring to become invisible until you use another action to make it visible, until you remove the ring, or until you die. If you die while wearing the ring, your soul enters it, unless it already houses a soul. You can remain in the ring or depart for the afterlife. As long as your soul is in the ring, you can telepathically communicate with any creature wearing it. A wearer can't prevent this telepathic communication.
• Ring of Bashful Bashfulsson - The Elder of Arms: Ring of Protection - You gain a +1 bonus to AC and saving throws while wearing this ring.
• Ring of Hurgarn Boulderkind - The Elder of Order: Ring of X-Ray vision - While wearing this ring, you can use an action to speak its command word. When you do so, you can see into and through solid matter for 1 minute. This vision has a radius of 30 feet. To you, solid objects within that radius appear transparent and don't prevent light from passing through them. The vision can penetrate 1 foot of stone, 1 inch of common metal, or up to 3 feet of wood or dirt. Thicker substances block the vision, as does a thin sheet of lead. Whenever you use the ring again before taking a long rest, you must succeed on a DC 15 Constitution saving throw or gain one level of exhaustion.
• Ring of Tysrin Whitbeard - The Elder of Justice: Ring of Truth Telling - While wearing this ring, you have advantage on Wisdom (Insight) checks to determine whether someone is lying to you.
• Ring of Hekheni Leadforge - The Elder of Secrets: Ring of Obscuring - This band of iron resembles a skull and is cold to the touch. It has 3 charges and regains 1d3 expended charges daily at dawn. As an action while wearing the ring, you can expend 1 of its charges to cast the fog cloud spell from it, with the following changes: the cloud is centered on you when it first appears, and the spell lasts for 1 minute (no concentration required).
• Ring of Krassid Ardent - The Elder of Trade: Ring of Free Action - While you wear this ring, difficult terrain doesn't cost you extra movement. In addition, magic can neither reduce your speed nor cause you to be paralyzed or restrained.
