But I assume I cannot just add monster_regeneration to the SAs of Gordon, or can I?
You could add it but it would not accomplish anything.
The name of the SA you want to add is "monster_Regeneration".
Not a big difference....but a very important difference.
You should be able to add that SA to any monster if you
want it to enjoy the benefits of the SA. When you add
this particular Special Ability, you will want to specify the
parameter.....the parameter appears to define the number
of hitpoints regained per round of combat.
The hook is documented here:http://dianneandpaul.net/UAF/Help/SAStartCombatRound.html
And you can see that it must be attached to a combatant
in order to accomplish anything. Manikus will have to explain
how the SA gets attached to a combatant. It must be that
there is a "regeneration" SA that causes the 'monster_Regeneration"
to get get attached to the combatant at start of combat. You
did not mention finding that in the database.
