This pdf is 4 pages long, 1 page front cover, 1 page editorial/SRD, leaving us with 2 pages of content for 5 feats to modify the unseen servant spell, so let's check this out!
the feats are:
-Force Servant: The unseen servant counts as a force effect and thus is immune to damage and can manipulate ethereal objects.
-Greater Servant: This feta modifies your unseen servant so it has an effective str-score of 6, can perform tasks of up to DC 14 and keep up with movements like climbing, flying etc., even if you move more than 15 ft.
-Unseen Actor: Your unseen servant can interact with figments you create, adding minor real effects to your illusion and thus making it harder to see through. The unseen servant can slo be used to enhance your stealth. This one's really creative and cool -bravo!
-Unseen Craftsman: The unseen servant can take the aid another action when an unskilled assistant could do so and gain access to your Craft and profession skills.
-Unseen Squire: Your unseen servant can be assigned to other characters to stow items safely away or produce them, prepare a weapon etc. and enables the character with such a squire to accept or pass items as a free action- the servant could also reload a crossbow or firearm (though it takes long), carry a shield or apply a potion to the character. This feat is AWESOME - not only is it clever and cool, just think about it: With some minor reskinning, you'll have a nice framework for some kind of beneficial haunting/friendly spirit-themed characters - Kudos and two thumbs up!
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 needs none at this length. Every time I think I'm getting finally tired of these spell-feats one-man-feat-factory Owen K.C. Stephens manages to pump out yet another stellar pdf full of great feats with yet another one or two inside that can only be considered innovative and cool. This is another one, and one that ranks among the more creative and interesting spell-feat BPs. My final verdict for this cool, creative little file will be 5 stars seal of approval - the squire feat alone is worth checking this out.
