This blood-red, triangular stone increases the bearer’s Dodge DV by one. (This bonus applies to the final value, not the pool used to calculate it.) Setting this hearthstone in an edged weapon also grants a +1 bonus to all Melee attacks the bearer makes with that weapon.

This flat, crystalline rectangle is normally clear but becomes cloudy when attuned to a spell. By attuning this stone to a specific sorcery spell, the bearer can reduce that spell’s mote cost by (her own Essence x 2). However, this stone cannot reduce a spell’s cost by more than half. Also, no combination of this stone with similar effects (such as the No Moon Caste ability) can reduce a spell’s cost below 1 mote. While the user can possess more than one of these stones, only one can be attuned to a particular spell. Attuning this stone requires the bearer to meditate quietly with the stone for a number of hours equal to the normal Essence cost of this spell.

The bearer of this cloudy, almond-shaped gem can breathe easily in any surroundings, such as at high altitudes, in smoke or toxic gases, or even underwater or buried alive.

This spherical white stone looks like a tiny, solidified cloud. Whenever the bearer of this stone desires, she can walk upon the air instead of the ground. Although she still moves at her normal movement rate, the character can walk safely across water or quicksand by walking on a layer of air lying above the surface. In addition, the character can walk up or down the air as easily as others walk up or down a staircase. With sufficient climbing, the character can walk along miles above the ground. If the character trips or is knocked down, however, she can still fall to her death unless she can get her feet under her; her player must successfully roll (Dexterity + Athletics) at difficulty 3. Also, the stone only allows the character herself to move in this fashion. Any steed she rides must still travel along the ground.

This clear, reddish-orange teardrop enables its bearer to ignite any flammable material simply by touching it with the stone and breathing on it gently. The stone produces a brief magical spark. All fires lit by an ignition gem are completely ordinary from then on and can be extinguished normally.

This hearthstone looks like a smooth nugget of polished iron. Its bearer can vividly recall (and mentally relive) any particularly positive and will-reinforcing memory. This recollection fires her resolve, enabling her to recover one point of temporary Willpower each day. This is in addition to any Willpower recovered through the normal, daily Conviction roll.

This orange-and-red crystal looks like a frozen tongue of flame. It bursts into flames the instant the bearer places it on any solid surface. Regardless of the weather, the stone creates a fire two meters in diameter, which burns without fuel and is hot enough to keep a dozen people warm and dry even in heavy rain or extreme cold. The stone will ignite a flammable surface. The bearer may safely snuff the fire with a thought. Otherwise, it burns until sunlight strikes it on the following dawn.
