By 11th level, characters are shining examples of courage and determination—true paragons in the world, set well apart from the masses.
Paragon tier adventurers are a lot more versatile than they were at lower levels, and they can find just the right tool for a given challenge. They can spend action points to gain additional effects, are able to use magic rings, and can sometimes regain limited powers they’ve expended. In combat, they exploit short-range flight and teleportation, making difficult terrain less important, and might be able to turn invisible or resist specific damage types. They also have ways to regain hit points beyond healing surges, including regeneration, so they can complete more encounters between extended rests. On the other hand, monsters at the paragon tier have more ways to thwart these new capabilities, including their own flight, damage resistance, and blindsight.
Rituals at the paragon tier begin to give characters magical ways to gather information and overcome obstacles. Divination rituals such as Consult Oracle grant access to knowledge they might otherwise not have, while View Object can make some kinds of mysteries obsolete. Exploration rituals such as Passwall and Shadow Walk let a party bypass solid barriers and quickly travel long distances.
Adventures: The fate of a nation or even the world might depend on momentous quests that such characters undertake. Paragon-level adventurers explore uncharted regions and delve long-forgotten dungeons, where they confront savage giants, ferocious hydras, fearless golems, evil yuan-ti, bloodthirsty vampires, crafty mind flayers, and drow assassins. They might face a powerful adult dragon that has established a lair and a role in the world.
