The dragons you killed had limited loot:


2x Draconic Ring of Energy Warping:
Resist 10 all elements
+4 Energy bonus to saves versus breath weapons.
When struck with a breath weapon that deals damage, a third of the damage is dealt initially.
Another third is dealt on the subsequent round, and the round after that. Damage is dealt at the same initative step that the breath weapon was cast on.

3x Draconic Ring of Guile:
Tongues
+6 to Bluff and Sense Motive
Suppress Natural Urge: You can suppress your natural aggressive social urges with an act of willpower.
Alternate Form: You can assume any animal or humanoid form of Medium or smaller as a standard action three times per day. You can remain in the alternate form until you choose to assume a new one or return to your natural form. If you already have this ability, it is instead usable an additional three times per day.

2x Draconic Ring of Forest Hunting:
See Invisibility
Speak with Animals
+4 to Spot, Search, Survival, and Listen
In areas of visibility limited by fog or other obscuring effects, you can see twice as far.
In forested areas, you gain fast healing 5/.


Draconic Ring of Resurrection:
If slain with this ring, you will resurrect at your horde after one week's time.
If you don't have a horde, you'll resurrect in your nest with -2 Con.
If you don't have a nest, you'll resurrect in your lair with -4 Con.
If you don't have a lair, you'll resurrect near where you set when you put this ring on last, with -6 Con.
Con penalties can be removed with a special Remove Curse cast with 2000 gp of materials for each point restored.

(this was on Palsartone, the Great Wyrm Blue Dragon)



Necklace of Attunement:
This allows the use of the Orb of Tiamat. I mean, you know, if you are a dragon.

Necklace of Arcanistry:
This grants constant use of Arcane Sight
While wearing this, you have greater insight into magical patterns, runes, and the area effect of spells themselves.
This manifests as a +6 to Knowledge Arcana and Craft checks related to these objects, as well as certain insights.
