The table of stats is in the upper-left section of the tab. The pool
text field in the upper-right indicates how many points you have to spend. By
default you can trade points on a point-for-point basis by lowering stats to
raise the pool and then raise stats to lower the pool. By clicking on the Roll
button you can re-randomize your stats. You can pick the randomization
method by using the Options->Stat Roll Methods menu item. You can
also purchase stats by clicking on the Purchase Mode checkbox. You can
change the cost of stats by selecting the Options->Purchase Mode...
menu item. When in Purchase Mode if you click on the Roll button
all your stats will be set to 8. In Purchase or Roll Mode, if you click on the Zero
button it will zero your pool. Typically for converting high-level
characters you can click on the Unlimited Stats Pool button so you can
change your stats at will, and once your stats are at your desired levels you
can click on the Zero button. Characters who do not have a class yet are
restricted to have stats no lower than the Stats Min field and no
greater than the Stat Max field.
The middle section lists all your known Languages - either by means
of race, class or skill. Some races and classes gain optional languages. These
languages can be selected by clicking on the Choose button.
The bottom section lists all your special abilities. Currently it isn't
possible to edit them directly, though this is in the plans.
