Crystal clover
Shimmering crystal clover was a temporary artefact gifted to adventurers during a Garden promotion. Shimmering with an air of fragility, its long crystal stem branched out into broad leaves, each formed of delicate green glass. The artefact granted a magical green aura each time the owner plucked one of its four leaves. A lucky boon to the hunter, the aura granted a month-long critical hit bonus. When all the leaves are plucked, the remnants of the clover vanish in a verdant flash.
