The animal companion archetype Totem Guide gives the following ability:
"Spiritual Guidance (Sp): At 3rd level, a totem guide can use guidance as a spell-like ability at will as a full-round action, targeting itself or its master. In addition, a totem guide’s master can spontaneously cast the following spells while adjacent to the totem guide by sacrificing a spell slot of equal or higher level: detect animals or plants (1st), augury (2nd), helping hand (3rd), divination (4th), commune with nature (5th), and find the path (6th). The totem guide serves as a divine focus for these spells, but costly material components must still be provided. This ability replaces evasion.
"
Does this allow me to "lose" a prepared spell for one on the list, similar to how a cleric and spontaneously cast cure/inflict spells and how a druid can spontaneously cast Summon Nature's Ally? Can I use up a prepared slot that I've left empty for the day?
