This pdf is 3 pages long, 1 page introduction/front cover, 1 page SRD, leaving 1 page of content, so let's check this out!
This pdf expands the options of spellcasters to make use of the spiritual weapon spell via feats:
-Large Spiritual weapon lets you summon a large spiritual weapon at one slot higher. D'uh.
-Spiritual Arcana lets you trade in bonuses received from your wisdom-modifier to make the weapon e.g. anarchic, flaming, keen etc.
-Spiritual Arsenal lets you determine the kind of weapon you get, no longer limiting you to your deity's favorite weapon.
-Spiritual Sheath is perhaps one of the coolest feats herein: It lets you sheathe your spiritual weapon, essentially suspending the spell until you "draw" the weapon again. Makes for a great way to e.g. escape from capture or dire situations and offers a lot of planning and roleplaying potential.
-Spiritual Specialization lets you add your highest non-wisdom attribute-modifier to damage with your spiritual weapon.
-Two-Spirit fighting replaces your spiritual weapon with two, each dealing a base of 1d4 damage and opens up a whole slew of new cleric fighting styles. Neat!
Editing and formatting are top-notch, I didn't notice any glitches. Layout adheres to SGG'S 3-column standard and the pdf has no bookmarks, but at this length needs none. I really like how this pdf takes a venerable spell and expands its options, essentially taking a piece of magic and fusing it with feat-mechanics to develop signature abilities and moves without being unbalancing. Especially spiritual sheath is a plain genius and at the low price point, I can definitely recommend this pdf - in fact, I hope to see more pdfs that take different components from magic and marry them with e.g. feat and(or skill-mechanics. Thus, my final verdict will be 5 stars.
