Functionality
Deciphering a soultech device is a mix of insight and interrogation, experimentation and negotiation. To reflect this, the person attempting the analysis may choose one of his three mental abilities — Intelligence, Wisdom, or Charisma — to use as his skill bonus. The DC of the analysis task check is usually 20, plus any bonus the soultech item has to the same attribute
Getting all the functionality out of a soultech item is akin to peeling an onion. It has one layer per point of its highest mental ability modifier, plus one for every two
modifier points (rounded up) in the other two mental abilities. Removing each layer requires a separate check. The item is fully under the character’s control when all
layers have been removed. Removal of the outermost layers will unlock the simplest functions of the device; each successive layer opens more and more functionality.
Alternatively, if there aren’t that many functions, unlocking layers can make the device less recalcitrant or contrary.
Example:
Janus of Three Hills Village has spent some time
dealing with his greatest treasure, a self-aware plasma pistol,
class MX-QR3, which he has learned to call simply “Max.”
Max talks to him through a dermal telepathic link when he
holds it in his hands, and their conversations are both
enlightening and confusing. Janus often thinks Max is laughing
at him. Max has Int 12, Wis 14, and Cha 10, for a total of 3
analysis layers. (Two from the Wisdom of 14, +1/2 from the
Int of 12, rounded up to 3.) Janus has managed to open one
such layer, enough to allow the gun to let him fire it.
One day, a pack of baddar bandits attacks Janus. He draws
Max and begins firing. Max’s recalcitrance bonus is +2,
for the two unanalyzed layers. The GM rolls a 19 + 2 =
21, and Max balks. The GM explains that the fragments
of military uniforms the baddars are wearing are in Max’s
“Allied Forces” database, and Max won’t fire on them until
he (Max) is more comfortable with Janus’ authority (i.e.,
until more analysis layers have been removed). Janus uses
some curses Max taught him, and draws his sword. At
least the sword never talks back.
