Dyescape allows client modifications that have no impact on your gameplay or the experience of others. Modifications that serve to benefit your experience of the game, such as OptiFine or Labymod, are allowed. Things like ESP, X-Ray, MobAura, or any modifications that give you an unfair advantage, are not allowed.
If a player is found to have an unfair advantage, their access to Dyescape’s game servers will be revoked for an appropriate period of time. If a player believes they were unfairly punished, they can appeal here.
