The shield formula is pretty simple. Take the base strength, look at the difference between hull mass and optimal mass and create a modifier to the base strength based on the linear interpolation between the shields best and worst modifier depending on whether you're over or under weight.

Shield Optimised Masses:

1 13t 25t 63t
2 28t 55t 138t
3 83t 165t 413t
4 143t 285t 713t
5 203t 405t 1013t
6 270t 540t 1350t
7 530t 1060t 2650t
8 900t 1800t 4500t

The difference of 40t is not enough to create a -25% difference in it's base shield strength. It's more like -2.5% with an average shield generator.

The exponent is set too high after investigation. I assumed as did some other designers that didn't set this up that it was linear. Evidently it wasn't and we've been discussing the reasons for it and whether it should be changed. The conclusion is to lower the exponent to make it more linear than it is now so there is some meaningful difference between all pips. The side effect of this would be that the default damage reduction at 2 pips will be higher than it currently is making all ships feel a bit tougher in general. But on the flip side lowering your pips will make you feel weaker too where as before it didn't really change anything.

The shield strength doesn't change at 0 pips or 4 pips. What has changed is how strong the shield is at the pip levels between them. I.e. 1, 2 and 3 pips will reduce damage slightly more (around 10-20%) than they currently do so as to flatten that curve above.

Shield mass rating is based on the Hull Mass. The anaconda is indeed 400t of hull before any modules are fitted and that is what the generator uses to determine shield strength. If that number could be lowered the strength would go up given the same generator but you can't do that. In future it might be possible to fit modules that can decrease the hull mass for the purposes of shield strength calculation (think shield boosters or something).

The ship itself defines the base shield strength however so typically as ships get bigger there base strength goes up. Also a larger ship might end up with a lower total shield strength than a smaller ship but when receiving damage the larger ship will nullify a lot of the damage from smaller weapons where as the smaller ship wouldn't.

The shields just modify the base shield strength defined by the ship itself. A Python has a base strength nearly 3 times as high as an Asp's. The difference in optimised mass and actual hull mass will alter the modifier that is applied to this base strength. If the optimised mass and hull mass are the same you get the base ship's shield strength. Higher rated modules will allow the modifier to shift more favourably in both cases of hull mass being lower or higher than optimised mass.

Shields are balanced in the only way that makes any sense that allows a single shield generator to fit on multiple ships of varying size.

Imagine the shield generator as having a finite resource that it uses to produce a shield. Spreading that resource other a larger area will result in a weaker shield at any single point. A smaller area would result in a stronger shield at any single point. With that scheme in place it makes sense to alter the strength of the shields based on some factor of size so that a puny sidewinder shield can't just provide an Anaconda with a reliable and strong shield when the anaconda is huge in comparison (it/s not fair and makes no sense). Thus a shield generator is optimised for a certain hull mass which is a convenient way of encoding size into the ship's stats. If the ship has a lower hull mass it's like your able to spread the shield energy over a smaller area so it gets stronger at any single point. Being over that size results in a thinner and weaker shield at any single point and going to0 big just results in a shield so thin it doesn't work.

The only other way of doing this would be to have bespoke shield generators for every single ships in the game and not something we're prepared to do.

The shield formula is pretty simple. Take the base strength, look at the difference between hull mass and optimal mass and create a modifier to the base strength based on the linear interpolation between the shields best and worst modifier depending on whether you're over or under weight.

If you're exactly at the optimised mass then you'd get a modifier of 1 so no change.

A C2 shield generator has 28t 55t 138t mass curve and modifier limits of 1.5 to 0.5. So being at 28t would give you a modifier of 1.5 to base strength. Being at 138t would give you a 0.5 modifier to base strength. Being somewhere in between would be a linear interpolation of those values and 1.

Sidewinders firing pulse lasers at an Anaconda for example get their damaged cut to 1/3 their normal damage potential. That might throw such a test in game because you don't know the exact numbers behind how weapons and ships compare to one another other than the vague notion that small weapons are weak against big ships.

If you want to ensure you're doing the max damage the weapon is capable of you need to use a huge weapon as that will always do it's best against any ship in the game.

It ensures that it's always better to fit the largest weapons you can if you want to fight equal or larger ships effectively rather than just loading up on as many small and cheap weapons as you possibly could. Now you have to choose between wanting to target smaller ships and taking smaller weapons that will fire faster and track quicker or fighting larger ships and dealing with weapons that fire slower but do appropriate damage.

With a Class 4 shield generator the Asp will be better off because it's base strength is high enough that even with the favourable modifier to the cobra (who has a lower hull mass than the optimal mass of the generator) it ends up with more shield strength.

Hull mass doesn't change at all. Seeing as the formula only cares about hull mass it should be pretty clear that cargo mass doesn't affect it. So no, cargo mass doesn't weaken shields.

We will be displaying actual shield values, just didn't make it in time for release.

## A note on shields

Any strike on a shield will prevent regeneration for a few moments. They don't start to regenerate the moment they stop taking damage.

Using shield cells generates significant heat. There's a five second delay before they kick in. We think that this makes for some interesting decisions concerning how to manage your ship heat either side of the fence.

What we're really after, is feedback from folk who are trying various loadouts and combat tactics. Just jamming the fire button down is, for this beta, no longer always a safe option (it's still an option, of course, but it can have consequences).

Accept that ship heat is now a "thing" to worry about, and explore how this affects your tactics.

## Pips to Sys

More pips in systems results in stronger shields and don't have any effect on their recharge rate. The only time pips affect the shield recharge time is when you have less energy in the system capacitor than the shield needs to recharge. In those cases adding more pips (improving the capacitor recharge rate) will ensure more energy is being added than being taken away over time. If you have a full capacitor when your shields go down then you'll see the recharge rate be exactly the same up until the capacitor drains and the bottle neck becomes capacitor recharge rate. Better power distributors by default fill up a bit faster.

In build 1.1 there was very little difference between 0-2 pips and difference between 0 and 4 was 150% so with 4 pips to SYS you had 2,5x stronger shields, add to that 8 utility slots on Anaconda filled with A shield boosters and you have flying fortress.
