A question related to this:
After an intro chapter to my game, I am allowing slight character changes for the PCs and introducing Deeds. Now, the Techmarine specific Deed in Rites of Battle doesn't seem to make much sense to me.
Here it is for those who don't have RoB.
Omnissiah's Calling - Speciality: Techmarine
Cost: 500 xp
Due to ancient pacts between the Adeptus Mechanicus
and Adeptus Astartes, Space Marines with the talents for
technology are allowed to train on Mars with the Priesthood
of the Omnissiah. It is a long journey and upon returning to
their Chapter after years of training, a Techmarine is never
viewed the same again by his peers.
While on Mars, the Battle-Brother is taught how to work
with the Machine Spirits and commune with the Omnissiah.
This shift from his primary role as a warrior from his Chapter
to a priest of the Machine God places the Techmarine in a
strange place between two worlds, not truly belonging to
either. The Techmarine is, however, the sole mechanism by
which the Space Marines are able to wage war. Without their
knowledge, they would be unable to manufacture their power
armour they wear, the Rhinos they ride to battle, or the bolt
shells they fi re. Without the presence of the Techmarines, a
Chapter ceases to be able to fi ght.
Apply all of the following changes to your character:
Talents: You gain the Electro-Graft Use Talent.
Bionics: You gain ONE common craftsmanship bionic of your choice.
To me, this sounds like you are paying 500xp for a talent you get upon character creation as a TM. The only benefit I see is an extra bionic of your choice.
What am I missing? Why is this good? What makes this stand out as something I or my players that are TMs would want to pick?
