The sacred keepsakes detailed below give halflings new options when casting a particular 1st-level divine spell (sacred keepsakes have no effect on arcane spells). When used as an additional divine focus for the spell, a keepsake gives the caster the option to make that spell more effective or simply different. Each keepsake earned at the end of a halfling’s coming of age task is unique and usually irreplaceable. However, a halfling who loses his keepsake might, if especially devoted, gain a nearly identical copy as a reward for completing a particularly important quest or assignment that directly benefits his faith.
Many halflings who are divine spellcasters attach their keepsakes to their holy symbols to prevent loss and to keep the keepsakes handy for casting spells. If the keepsake is too large or unsuitable for attaching to a holy symbol (such as the half-deck or game piece), it is worn on a strap around the neck or wherever the holy symbol is worn. If the keepsake is near the holy symbol, a halfling can grab them both at the same time with one hand and cast the spell as normal. If the keepsake is hidden away, the halfling must spend a move action to retrieve it before casting the spell. Only the halfling who earned the keepsake can use it for the following purposes. These keepsakes are not magic items and do not radiate magic.
Since they only offer the chance to cast a variation of one specific 1st-level spell, these keepsakes have little real impact upon a particular character. GMs who wish to make a keepsake more powerful, perhaps by offering up variant spells for each spell level, should probably require that the character spend a feat to balance out the advantage gained.
