Weapon Modification Rules

Some people want to modify their weapons to do greater damage, have a greater payload, or have a better range. These rules are made especially for that purpose. The character must make a successful Weapons Engineer skill roll two out of three times per weapon. Sometimes the character wishes to modify another of the exact same type of a weapon, performing the exact same modification. To do this he must roll again two out of three times with a bonus of 10% added every time they have successfully modify that same model in the same way.
A weapon's damage, range, and payload can only be increased once.

The weapons have been broken down into Light, Medium, and Heavy depending on the MAXIMUM damage per shot. The breakdown is as follows:

(L) Light Weapons = 1-12 Mega Damage
(M) Medium Weapons = 13-39 Mega Damage
(H) Heavy Weapons = 40+ Mega Damage

Possible Damage/Range/Payload Increase
Light	Medium	Heavy	Difficulty	Skill Modifier	Cost for Parts
+10%	+5%	+4%	Easy	-10%	15% of original
+20%	+10%	+9%	Moderate	-15%	25% of original
+30%	+15%	+12%	Difficult	-20%	30% of original
+40%	+20%	+15%	Very Difficult	-25%	35% of original
+50%	+25%	+18%	Heroic	-30%	50% of original

Note: If a weapon is to have it's damage increased, the percentages are multiplied by the maximum possible damage that the weapon can do. Add the extra percentage to that total and round to the nearest whole number to find the new damage ability.
Otherwise, the payload and range are increased by the percentage amount.

Example #1: A weapon that inflicted 1D6x10 damage that had a "difficult" upgrade by adding 12% would now do 1D6x10+7. (Formula: 60 x 12%=7). The character would roll to see how long it took.

Example #2: A weapon that inflicted 3D6 had a payload of 20 shots per E-clip. A "moderate" upgrade would provide an extra 2 shots per E-clip (Formula: 20 x 10%=2). The new payload is 22 A roll on the time chart would determine how long the upgrade took.

For each attempted (3 rolls) upgrade, the player must roll once on the time chart below. This determines, according to the difficulty level, how long the character spent on this single attempt. If the player fails the two out of three rolls, then they wasted that amount of time trying the upgrade.

61-70	7 days	4 weeks	8 weeks	12 weeks	18 weeks
71-79	8 days	5 weeks	10 weeks	14 weeks	20 weeks
80-88	9 days	6 weeks	12 weeks	16 weeks	24 weeks
89-93	10 days	7 weeks	14 weeks	20 weeks	24 weeks
94-97	11 days	8 weeks	16 weeks	24 weeks	24 weeks
98-99	2 weeks	10 weeks	20 weeks	24 weeks	28 weeks
100	3 weeks	12 weeks	24 weeks	24 weeks	32 weeks

There are, of course, different environments that a player will be when attempting a modification. The following modifiers have been created to compensate for basic situations. All modifiers are accumulative.

Situation Modifier Chart

Environment	Skill Penalty	Time difference
Rush job	-15%	-25% to time
Improper tools	-20%	+25% to time
Field job	-10%	+15% to time
Distracting conditions	-8%	+10% to time

If all three rolls are failed, then the weapon becomes completely ruined and unusable. If only one of the three rolls was successful, the GM should determine whether there were any consequences (i.e. meltdowns or side effects) that occur while the weapon is being tested.
