Spires of the Endless Library

Waytravel to the Endless Library...

T
he tips of the spires of the Endless Library stick out among the sands of the Almaghni Desert. Those who know what to search for can find incalculable knowledge within, but be warned, there are many who would pursue this knowledge who are unwilling to share.
Tier II Waypoint | The Iron Coin will allow anyone through. The monsters present flee instinctively should anyone of 10th level or higher arrive.

Prerequisites: Reaching the Dungeon

Dungeon Link The Endless Library is one day's travel south from the waypoint. You must complete the following before attempting the dungeon.

• Complete a combat encounter which includes a hostile Abjurer, Conjurer, Diviner, Enchanter, Evoker, Illusionist, or Transmuter, and complete a Harvest Challenge at the end of the encounter to recover their spellbook intact.
• Successfully complete a difficult social/investigation skill challenge to hear rumor of the library's location
• Successfully complete a moderate tracking skill challenge to know how to get there; each failure adds 12 hours to your journey
• For every 24 hours you are traveling to the Endless Library (minimum of 24 hours), you must make 6d100 rolls (4 during the day, 2 at night)
• For every roll of 25 or below, you have a random wilderness encounter !table wilderness

Desert Conditions

The Almaghni Desert is particularly dry and inhospitable, though the powerful enchantments surrounding the Endless Library hold the worst of its storms at bay. When seeking a site to rest for the night, you must succeed on a DC 14 Survival check. Failure means you benefit only from a short rest.

• Sandstorms plague this region regularly. Roll 1d20. On an 11 or higher, a sandstorm is present; factor in the following:
• If you do not have a tent or some other type of windscreen, make a DC 12 Constitution saving throw; failure means you will benefit from a short rest only.
• On an 19 or higher, even a tent is not sufficient and you will benefit from a short rest only.
• Before making another survival check to find shelter, you must roll 4d100. For every roll of 25 or below, you have a random wilderness encounter. !table wilderness. Once you successfully find a campsite, this character never needs to look for another campsite in this region again. Sandstorms will still be a problem, though.

In addition to affecting your ability to sleep, the following regional affects apply for the next twelve hours. Here is an example: If I rolled a 4d100 and the results were 67, 21, 88, 12, then the first two rolls will incorporate the regional effects. The first 6 hours, nothing happens. The next 6 hours, random wilderness encounter with these effects. The next 6 hours, nothing happens and the storm is gone. The next 6 hours, random wilderness encounter with no sandstorm effects. Combat encounters in these conditions awards a 10% bonus. The reviewing DM may also grant additional cash rewards for utilization of this system.

Sandstorm

Any creature in the sandstorm must make a Constitution saving throw DC 15 or be blinded until the sandstorm ends. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. A creature cannot be blinded by the sandstorm if it’s wearing goggles or something that protects its eyes. Any check that relies on sight is made with disadvantage for the duration of the sandstorm.

Strong Winds

A strong wind imposes disadvantage on ranged weapon attack rolls and Wisdom (Perception) checks that rely on hearing. A strong wind also extinguishes open flames, disperses fog, and makes flying by nonmagical means nearly impossible. A flying creature in a strong wind must land at the end of its turn or fall.

Extreme Heat

A creature exposed to the heat of the desert and without access to drinkable water must succeed on a Constitution saving throw at the end of each hour or gain one level of exhaustion. The DC is 5 for the first hour and increases by 1 for each additional hour. Creatures wearing medium or heavy armor, or who are clad in heavy clothing, have disadvantage on the saving throw. Creatures with resistance or immunity to fire damage automatically succeed on the saving throw, as do creatures naturally adapted to hot climates.
