These incenses will enhance all divination, great or small.
Whether the operation be one of sortilege (such as casting runes) or a grand operation, two easily accessible divination incense ingredients are extremely useful to have on hand at all times: namely, gum mastic and cinnamon (the latter preferably in oil or essence form).
Gum mastic may be obtained at any good art materials suppliers as it is used in picture varnish. Cinnamon can be obtained from many grocery stores or markets.
These two ingredients may be fumed on top of charcoal by themselves as divination incense or mixed with the following traditional recipes to form a more powerful blend.
Any or all of these may be mixed to advantage with Solomon's Seal and/or holy thistle herb to enhance effect. Experiment to see which type suits you best.
Dittany of Crete is mixed with any incense where materialization is required in the operation. Most if not all of the herbs aforementioned may be obtained by any shop that handles the sale of botanicals.
