This imperfect, rose-tinted gemstone resembles a teardrop or a broken heart depending on its orientation. Its pale facets are typically marred by a single crack or chip near the gem's middle.
Once per day, the bearer may spend a standard action to transfer 3d6 hit points from himself into the gem. This deepens the gem's color, with a stronger color indicating more life energy stored in it. The gem can store a maximum of 18 hit points. If any hit points are stored in the gem, the bearer may touch it himself or another creature as a standard action, transferring all the stored life energy from the gem to the target creature, healing it a number of hit points equal to the amount stored in the gem. This returns the gem to its normal color.
Maybe too expensive for low levels, but at high levels it is a must have for non-magic characters. 18 HP of healing that anyone can use on anyone can save lives.
