This metal mask is a vestment of an entity known as a Reaper of Challenge. There is little known about what these "reapers" are, but it is certain that they are always involved in historical events of high weight and importance. The mask was once of a different shape and material, found in the ruins of an ancient temple, but after some event that is known only to a select few, it changed into its current form.

While wearing this mask, you are filled with fortitude and determination that seems only natural to those who pursue their goals. You gain a +1 bonus to your AC and saving throws.

The Challenger. The mask has 6 charges. While wearing it, you can expend 1 or more of its charges to cast one of the following spells from it, using Wisdom as your spellcasting ability: command (1 charge), compelled duel (1 charge), heroism (1 charges), or geas (6 charges).

The mask regains 1d4+2 expended charges daily at dawn. The mask doesn't regain charges while the geas spell is active, but you can end it early, severing the compelled challenge instilled on a creature as an action.

The Leader.

The Seeker. Wearing this mask means embarking on a journey to find ways to challange yourself, seeking hurdles and obstacles to overcome and become victorious. The challenges may vary, but only you may see the opportunities before you. To invoke the magic of this mask, you must see the opportunity that falls under one of the three categories listed below. If you manage to prevail in conquering the taken opportunity, you are rewarded with a mystical boon, examples of which are shown in the table below, but may vary depending on the nature of your achievement.

Challenge. An opportunity that will prove an easy task for you (obstacles with DCs of 14 or lower) or take short time to accomplish (less than an hour) are considered to be challenges. Examples of such challenges can be winning a drinking game, climbing a small cliff or dealing a killing blow on a weaker opponent. Accomplishing the challenge rewards you with a challenge boon, which you can use once.

Goal. An opportunity that will prove to be a task of moderate or hard challenge (obstacles with DCs of between 15 and 20) or take some time to finish (several days or a week) are considered to be goals. Examples of such goals can be unveiling a location of a secret organization, surviving in a collapsing ruins or defeating a formidable foe. Accomplishing the goal rewards you with a goal boon, which is available for you for 1 week.

Achievement. An opportunity that will prove a very hard or near impossible task for you (obstacles with DCs of 21 or higher) or take very extended periods of time to accomplish (more than several weeks) are considered to be achievements. Examples of such achievements can be fulfilling a life-time dream, reaching mastery in a craft, finding a mythical relic or defeating a foe well-above your own powers. Accomplishing the achievement rewards you with an achievement boon, which is available for you for 1 year.
