Vis wax

Vis wax is a sticky goo made from runes, available from the Rune Goldberg Machine distraction and diversion. It has a variety of uses, including extending the durations of certain auras, increasing divine location gathering limits, or increasing the duration and reward of or rerolling daily challenges.

Up to 100 vis wax can be obtained each day. It cannot be used to extend Jack of Trades or Wisdom auras, but it can instead be used to reset them once per day, allowing for a second use in a 24 hour period.

Uses

 * Reroll Daily Challenge - Allows a player to change a daily challenge they don't wish to do for one in a different skill. Each daily challenge can only be rerolled once. If this is selected, the player is shown the potential new challenge, which they can accept or reject. Vis wax is consumed with either choice. If the window is closed for any reason, the daily challenge will not be changed.
 * Extend Daily Challenge - Players can choose to double the duration of a daily challenge (e.g. from one Complexity 6 Floor to two Complexity 6 floors) in order to receive double the experience reward upon completion. This will also double the value of the items contained in a Challenge Mystery Bag, if one is awarded for that particular challenge, as number of materials required will also be doubled.
 * Reset Aura - Players can reset certain auras once within each 24 hour reset period, allowing them to be used again immediately.
 * Extend Aura - Players may increase the duration of an aura's activation time, by either 50% or 100% of its timer. This effect will be applied on the aura's next activation and is temporary. Therefore it will prevent you from extending the duration while the aura is worn and active, so you must do the extension before activating the aura. For example, passive skill-boosting auras such as Greenfingers cannot be extended once worn and activated.
 * Reset Harmony Pillar - Players that have already planted a harmony moss seed in a harmony pillar and wish to change the skill can do so using 10 vis wax. This can only be done once a day.
 * Increase Divine Location limit - Players can increase the amount of items they can gather from Divine locations during that reset period. Players can choose to increase their limit by either 50% or 100% for a single reset period; only one choice may selected per period (meaning, for instance, it is not possible to increase one's limit by 150%).

Trivia

 * The word vis is Latin for "force" or "power." This is in line with the (subtly) stated purpose of the machine itself, which is to find out exactly what makes up the physical rune stones. It can be reasonably implied that the wax is a physical manifestation of the raw power of rune stones, hence its ability to effectively alter certain gameplay mechanics, albeit temporarily.
 * Prior to 3 November 2014, the cost to re-roll daily challenges was 10 wax, while extending a challenge cost 20. This was changed in the interest of "re-balancing" the costs, likely because of widespread sentiment that the low costs had made the challenge system "too easy."
