This spell makes 1 to 4 creatures or objects flammable. For the duration of the spell, they are as flammable as wood. If they catch fire they burn entirely and turn to ash in the time it takes wood of their size to burn. This fire is normal fire and may be extinguished by the usual means. It does not matter what materials the objects or creatures are made of. They can be inflamed by natural or magical fire or extreme heat, but the spell itself does not inflame them. Once they have caught fire they get damage from heat, but also turn to ash within the time specified. After that, the duration of the spell does not matter. Each creature or object gets a saving throw: if only one is the subject of the spell it has a penalty of -2 to its roll; if two are subject, each receives a penalty of -1; if three are subject, each receives a bonus of +1; if four are subject, each receives a bonus of +2. The material components are a chip of wood and the caster's holy symbol.
