Tri-Stat dX Combat Modifiers rules revision
By Zegon Destructacon

Listed below are modifications to Attack Situation Modifiers (Table 8-3) and
the Defense Situation Modifiers (Table 8-4) as presented in the Tri-Stat dX
book.  These are designed to, like most modifications, scale with the dice size
so as to not be impossable at lower dice sizes and pointlessly insignificant at
higher sizes.  Most of these can be countered with the Steady Hand combat
technique for attackers.

Called shots have their own section.

Trick Shots will have their own section.  Until then, use the system in the
book.

Bonuses are listed as negative values, while penalties are listed as positive
values.  Unless noted, round down bonuses and penalties.  All bonuses and
penalties, unless otherwise noted, have a minimum of 1 adjustment.  'None'
listings have no base adjustment.

Attack situation modifiers are applied to the attacker's attack roll.  Defense
situation modifiers are applied to the defender's defense roll.

Attack Situation Modifiers:

Attacker is:                                        Modifier

Taking an action to aim (Melee or ranged)             -X/4

Attacking multiple targets with one attack       +0, +2, or +4 per extra target
Attack with two weapons (same or different targets)...-(X+1, max of +9)
Attempting a Combined Attack                           +2 per extra attacker
Attempting to touch the target........................-3X/5
Making a Total Attack                                  -2 per def. sacrificed

  * A successful swim check only imposes an X/4 penalty.  An unsuccessful swim
  check imposes an X/2 penalty.  Creatures that are naturally waterborne do not
  recieve this penalty.  These include those with the water speed attribute,
  those with Adapatation (Underwater), and those who breathe water instead of
  air.  If a creature is naturally waterborn and cannot survive on land
  normally, impose these penalties to attack rolls, with a lowering check
  according to the character's body stat modified by physical conditioning.
