Incremental Improvements: You can increase (or decrease) your mech’s Strength, Dexterity, Fortitude Saving Throw, Will Saving Throw, Speed and Hit Dice. If you
increase (or decrease) them all, the mech’s size goes up accordingly but if you only increase some areas, the size remains the same.

**For the purposes of incremental increases, the City-Mech E and City-Mech F start with a -2 Dexterity score.
Size: Mech are divided by size. When you customize your mech’s stats, they become the stats of a larger size or smaller size mech.
Increment Cost: There are six stats that make up the base cost of a mech; Strength, Dexterity, Fort Save, Ref Save, Speed and Hit Dice. To upgrade one of these stats, by
one Size category, find the difference between the cost of your size and the next size up. Divide that cost by 6 (the six factors). That is the increment cost and it has been calculated
for you in the first column; Increment Cost (Gold/Man Hours).
Increasing a Stat: When you improve a Stat, choose one stat (Str, Dex, Fort, Ref, Speed or HD), find your current Size (or the size that stat is now associated with) and
pay the cost. The stat is improved by it’s increment for that size and becomes the next size up.
For example, if you want to improved your City-mech A’s Fort save (Base -2), you pay 12800gp and 20480 man hours and it would improve by +0. (Not much of an
improvement.) You would have to buy the next 6 levels just to get a +1 bonus. Add the cost of all 6 levels together to get the total cost.
Decreasing a Stat: You can decrease a stat the same way. The cost of the mech is reduced by the increment cost and goes to the next smaller level.
Increment: This is the amount the stat improves when you purchase one increment. If you want to buy more than one increment and the cost of EACH increment
together. This is also the amount of stat is reduced if you decrease the stat one increment.
Base: A normally mech of this size starts with this base value. It’s just a reminder.
Strength: Strength increases by +4 each size.
Dexterity: Dexterity increases by+2 when you buy 2 sizes.
Fort: Fort requires a lot of sizes purchased to get an increase.
Ref: Ref requires a very large number of sizes purchased to get an increase.
Speed: Speed increases by +1, +2 or +3 miles per hour per size purchased/
Hit Dice: Hit dice increase by +6, then +12, then +24, +48 and finally +96 as you purchase larger sizes.
Strength (Cost per +1 Str (Range)): Strength is normally allotted at +4 per increment. This is the cost in gold and extra man hours to increase the mech’s Strength by +1.
You start purchasing Strength at your size category. Once you buy 4 points of Strength, your mech has the Strength score of a mech one size category higher. To buy more Strength
you must purchase it from the next size category. The Strength ranges are shown in brackets. (See Chapter 2 in DragonMech or table 18: Mech Ability Scores by Size and Type).
A Colossal Steam Powered mech has a Strength of 30. Once you buy 4 points of Strength it has a 34 Strength. It now buys Strength as a Colossal II mech. If you buy
another 4 points of Strength it has a 38 Strength. It now buys Strength as a Colossal III mech.
For example, if your Steam Powered Mech is Colossal it normally has a 30 strength. If you wish to increase this Strength by +1 to 31, it costs 100gp and 160 man hours.
Let’s say you took the same mech and wanted to increase its strength from 30 to 40. Strength 31 to 34 it costs 100gp and 160 man hours per point. All four points of
Strength are purchased at this cost. Strength 35 to 38 it costs 200gp and 360 man hours per point. Four points are purchased at this cost. Strength 39 and 40 cost 400gp and 620
man hours per point. Two points are purchased at this cost. The total cost is an additional 2000gp and 3200 man hours. (See Table X: Example Costs of Improving Strength)
Table X: Example Costs of Improving Strength
31-34 (100gp and 160 man hours x4) 400gp and 640 man hours
35-38 (200gp and 360 man hours x4) 800gp and 1280 man hours
39-40 (400gp and 620 man hours x2) 800gp and 1280 man hours
Total: 2000gp and 3200 man hours
Decreasing Strength: If you lower your mechs Strength, for each -1 Strength you reduce the gold piece and man hour cost by the cost for the next smaller mech size.
Each time you remove 4 points of Strength, use the cost for the next smaller mech size. Each time you lower your mech’s Strength by 4, reduce the number of Payload Units (PU)
to the next smaller mech size (see Table 1: Payload Units by Size).
Cost per +1 Dexterity: Mech Dexterity effectively drops by 1 each level. To improve your mechs Dexterity you start by purchasing +1 Dexterity at your mech’s size.
Each time you purchase one point of Dexterity you must buy your next point as a mech one size larger.
For example, it costs a colossal steam powered mech 400gp and 640 man hours to increase its Dexterity by +1. It now purchases Dexterity as a Colossal II mech. For
another +1 Dexterity, it costs 800gp and 1280 man hours. The third point costs 1600gp and 2560 man hours, and so forth.
Dexterity is more expensive that Strength. It is much harder to make faster mechs than it is to make stronger mechs. You can buy 4 points of Strength for the same cost as
1 point of Dexterity.
Decreasing Dexterity: If you lower your mechs Dexterity, for each -1 Dexterity you reduce the gold piece and man hour cost by the cost for the next smaller mech size.
Each time you remove a point of Dexterity, use the cost for the next smaller mech size.
Table X: Example Costs of Improving Dexterity
9 400gp and 640 man hours
10 800gp and 1280 man hours
11 1600gp and 2560 man hours
12 3200gp and 5120 man hours
Total: 6000gp and 9600 man hours
For example, if your Steam Powered Mech is Colossal, it normally has an 8 Dexterity. If you wish to increase the Dexterity by +1 to 9, it costs 400gp and 650 man hours.
Let’s say you took the same mech and wanted to increase its Dexterity from 8 to 12 (a +4 total improvement). You take the cost for Size Colossal (its starting size) for the
first +1, the Colossal II for the second +1, Colossal III for the third +1 and Colossal IV for the 4th +1 and add them together to get the total cost from 8 to 12.
Math Notes: Be aware that because the Dexterity decreases with size, the cost to increase or decrease this score will be different depending on what size you start with.
You can not determine how much it costs to increase Dexterity from 9 to 10 and apply it to all mechs. It will be different for each size of mech.
