Hi,

i want do a spreadsheet for calculating the shield boost with different crystal implants and have a problem with the math behind.

All what i can find is this:

For the Crystal and Slave sets:
Alpha = 1% x multi = +3.01703578125% = 1.0301703578125x
Beta = 2% x multi = +6.03407156250% = 1.0603407156250x
Delta = 3% x multi = +9.05110734375% = 1.0905110734375x
Gamma = 4% x multi = +12.06814312500% = 1.1206814312500x
Epsilon = 5% x multi = +15.08517890625% = 1.1508517890625x

but i need for my spreadsheet the different numbers without one or more of each implants, so a excample for this is a mix of this implants:

Crystal
High Grade Alpha
Low Grade Beta
High Grade Gamma
Low Grade Delta
Low Grade Epsilon
High Grade Omega

or this:

Ocular Filter - Standard
Low Grade Beta
Neural Boost - Standard
Low Grade Delta
Low Grade Epsilon
High Grade Omega

i dont know how long i didnt need higher math but maybe anybody can help me with this ?
Or can tell me the math behind?

I know, many guys say this is not a good thing, but i want do this for my sheet to have some options what i need or not and how much boost i have with the different percents.

Step 1: Calculate the total set bonus.

For each implant that is fitted (doesn't matter whether it's high grade or low grade), multiply together the set bonuses for each implant. The set bonus can be found in the Show Info of the implant in-game. For a full high grade set of crystals it would be 1.15 x 1.15 x 1.15 x 1.15 x 1.15 x 1.5 = 3.01703578125x. For your example of:

High Grade Alpha
Low Grade Beta
High Grade Gamma
Low Grade Delta
Low Grade Epsilon
High Grade Omega

it would be 1.15 x 1.1 x 1.15 x 1.1 x 1.1 x 1.5 = 2.64037125x


Step 2: Multiply the implant boost bonus by the set bonus to calculate the effect of each implant.

This doesn't really matter whether the implants are HG or LG as the boost bonus is the same for each in crystal implants. Example:

Alpha = 1% x 3.01703578125 = 1.0301703578125x
Beta = 2% x 3.01703578125 = 1.0603407156250x
Gamma = 3% x 3.01703578125 = 1.0905110734375x
Delta = 4% x 3.01703578125 = 1.1206814312500x
Epsilon = 5% x 3.01703578125 = 1.1508517890625x


Step 3: Multiply the separate implant multipliers together to create an overall multiplier.

1.0301703578125 x 1.0603407156250 x 1.0905110734375 x 1.1206814312500 x 1.1508517890625 = 1.53633576412893

This multiplier is basically the % increase in the shield boost amount you will get from the crystal implants you've chosen.


That's the basic maths behind it and from that, it should be simple enough to put together a spreadsheet that calculates the total multiplier from any combination of implants. Whether the implant is HG or LG should only affect step 1 of the calculation above. If you decide to leave out a particular implant altogether (e.g. the Gamma), then that affects all 3 steps.
