 * Click on the name of a physical statistic (such as _STR_, on the _Physical_ tab) to roll a test.
 * Click on a weapon name (on the _Gear_ tab) to roll the skill test associated with it (e.g. _Firearms_).
 * Click on the Damage/Lethality associated with a weapon to roll it.
-    * For Lethality, the d100 test is evaluated, but regardless of the outcome the damage associated with rolling the equivalent 2d10 is also displayed in paretheses as lethality does not affect many creatures.

+## Where are the Specialized Skills Like 'Science' and 'Pilot'?
+Only one 'Typed' skill is shown for an Agent by default, that being Art (Painting), and it is *below* all the other skills.  It can be removed by clicking the trash icon inside the box for the skill.  Likewise, new typed skills can be added by clicking the _+_ button just above the section.
+
+This allows adding any number of skills as needed, without having dead space for unused skills.
+
+## Why Does the Lethality Roll Show Damage?
+For Lethality, the D100 test against the target lethality threshold is evaluated like a normal skill test. But regardless of the outcome, the damage associated with a non-lethal roll (2D10) is also displayed in paretheses as lethality does not affect many creatures.
+
+Note - the Lethality roll does not currently take into account the changes that rolling a critical on the associated attack roll involves.  For example, on a critical _Firearms_ check with a weapon with a lethality of 10%, the threshold doubles to 20%, and if that check fails the resulting damage doubles as well.

+## Where is The Breaking Point Shown?
+It is under the _Mental_ tab, as are the boxes to tick for _Incidents of Sanity Loss Without Going Insane_ and an Agents _Motivations_ and _Disorders_.
