The Wyrm Master can channel some of Tholaghru's power into the ground for 5 AP and 10 MP. A Twisted Wellspring lasts for twelve hours, providing the cost of 3 MP per AP tick is paid.
Each Wyrm Master may create a single Twisted Wellspring, and having multiple Twisted Wellsprings at one location can be beneficial, as this increases the power of the Wellsprings. Twisted Wellsprings may be placed inside or outside: As long as there is a door connecting the indoor and outdoor tiles, the effect applies both indoors and outdoors. If the Wyrm Master tries to place a Twisted Wellspring in a different location, the old Wellspring is removed.
The first benefit is that ALL Wyrm Masters who are members of the same faction (or allied faction) share the MP cost instead of the cost for their own specific Wellspring, starting from the Wyrm Master in the collective with the highest MP. That means that three Wyrm Masters could maintain their collective Twisted Wellsprings indefinitely. More than three Twisted Wellsprings will increase the MP cost by 1 for each additional Wellspring: four will cost 4 MP, 5 will cost 5, and so on, all drawn from the Wyrm Master in the collective with the highest MP.
One Wellspring: Up to six Wyrm Master pets will not decay for each Wellspring that is placed.
Two Wellsprings: Wyrm Master pets gain +1 damage. Non-faction Pets are no longer immune to auras.
Three Wellsprings: Wellsprings can be maintained indefinitely. Up to four additional demonic pets will not decay for every wellspring that is placed, with a preference for non-Wyrm Master pets. All Demonic Pets gain +1 damage.
Four Wellsprings: Wyrm Master Pets gain +2 damage and ignore auras. All Evil pets gain +1 damage.
Five Wellsprings: Up to two additional Evil pets will not decay for every welling that is placed, with a preference for non-demonic pets. Demonic pets gain +2 damage. Non-faction pets spend an additional AP and MP to attack.
Six Wellsprings: Wyrm Master pets gain +3 damage and no longer respect resistances or immunities (only Soak will reduce damage). Wyrm Masters may summon and rejuvenate pets for 20% less MP.
Additional Wellsprings will only increase the number of pets that resist decay.
How does this work factionally: Wyrm Masters count their wellspring and the wellsprings of their faction and factions specifically Friendly towards that faction to determine the benefit they and their factionmates gain from the wellsprings. This also means that the benefits can only be truly shared if the factions are allies. Pets get the highest bonuses afforded to them and they do not stack.
With six wellsprings:
Wyrm Master pets will have a +3 damage bonus, ignore auras, resistances, and immunities and be 20% cheaper to summon and rejuvenate.
Demonic pets of allies of the Wyrm Master gain +2 damage.
Evil non-Demonic pets of allies of the Wyrm Master gain +1 damage.
Non-faction pets cannot be immune to auras, and must spend an additional AP and MP to attack.
36 Wyrm Master pets will not decay, 24 additional Demonic or Wyrm Master pets will not decay, and 12 additional evil pets (which may be Wyrm Master pets or Demonic) will not decay for a total of 72 pets.
A Wellspring needs the active presence of their Wyrm Master to continue to exist. If the Wyrm Master leaves the tile, then their Wellspring will go "dormant" upon the next AP tick, no longer contributing to the collective. Their Wellspring will end if it is dormant longer than 66 minutes. Note that a Wyrm Master also does not NEED to place or even HAVE Twisted Wellspring to benefit from one, the skill only allows the Wyrm Master to place one and contribute to the collective Wellspring of the tile. However, a Wyrm Master must contribute to the Wellspring to derive full benefit: by not being an active part of the wellspring, they only get the benefits that Demonic pets in general get instead of receiving Wyrm Master-specific benefits.
