Yes, it's a Doctor Who reference.
The Tooth vs. Nail Coliseum Challenge immediately ends when one faction's adult dragons have all been eliminated (resulting in their faction losing) or a dragon from one of the factions reaches level 25 (resulting in their faction winning).

optional rules wrote:
Eye Adjustments: Eye types are no longer always cosmetic! Mutant eyes (Faceted, Multi-Gaze, and Primal) now affect dragons by granting them a special "asset" to aid them on their challenge journey. Click HERE to learn more about their acquisition and effects!
Fateful Motivation: Every time an "interesting" Coliseum drop happens, another battle must be fought by the active faction before their quota is considered complete.
Keep it Simple: The tallying system is removed. Instead, a familiar's effect only occurs if the dropped familiar has no element (neutral), and an elemental battle stone's effect only occurs if the advanced mage stone is dropped (aka: Enfeeble, Fossilize, etc.).
Poisoned Potions: Every time a potion drops, someone in the party who found it suffers a life point penalty.
Priority Party: The dragon guaranteed to fight in the Coliseum for the faction who fights first on a given day earns an additional ½ of a life point.
Unlimited Potions: Instead of having a restriction to the number and type of potions used for or by a faction, you may use them as often as you want for any members of either faction.
A War of Extremes: Changes to elemental battle stone effects are made to immediately incur the most extreme possible result. The following is a list of all applicable changes. If an element isn't listed here, then no change takes place. In order:

Poisoned Potions: Every time a potion drops, someone in the party who found it suffers a life point penalty.
The penalty is ½ of a life point for a minor health potion; 1 life point for a health potion; 1½ life points for a major health potion; and 2 life points for a cleansing tonic.
On a result of 1 or 2, the dragon with the most experience in the party suffers the penalty.
On a result of 3 or 4, the dragon with the intermediate experience in the party suffers the penalty.
On a result of 5 or 6, the dragon with the least experience in the party suffers the penalty.
If there is a tie in experience for any reason, all qualifying dragons suffer the penalty.

A War of Extremes: Changes to elemental battle stone effects are made to immediately incur the most extreme possible result. The following is a list of all applicable changes. If an element isn't listed here, then no change takes place. In order:
Icy Congealment: The randomized dragon from the active faction immediately pledges their allegiance to the opposing faction.
Light Enamorment: The randomized dragons immediately form a nest, if applicable. Otherwise, the randomized dragon from the active faction functions as a member of the opposing faction for the rest of the week.
Lightning Shock: The randomized dragon from the opposing faction immediately pledges their allegiance to the active faction.
Natural Venom: Multiply the number of days remaining until Saturday (including the day this takes effect) by ½. The result is the immediate life point penalty suffered by the randomized dragon of the opposing faction.
Plague Contamination: Multiply the number of days remaining until Saturday (including the day it takes effect) by ½. The result is the immediate life point penalty suffered by the randomized dragon of the active faction.
Shadow Shroud: All "interesting" Coliseum drops are applied to the double agent's faction.
Watery Drowning: Generate a random list of the dragons of the opposing faction and count how many days remain until Saturday (including the day it takes effect). Every dragon in those slots suffers an immediate 2½ life point penalty.
Windy Disorientation: Flip a coin. If it lands on heads, nothing happens. If it lands on tails, the randomized dragon of the active faction immediately pledges their allegiance to the opposing faction.
