On this condition, the second case is used. The third case has no relation.

When damage.amount = 6, this->decrease = 6 and this->percent = 0.3 the formulas return 0.35.

I did an additional test of the following topics.

This is not a bug right?

When the biter is damaging the player, the shield is also being recharged, so part of the damage is absorbed by the shield and the other part by the player.

That means the shield can be recharged when no energy source is ...

This is a mechanic change between older and newer versions.

In the current version, (To my great irritation) shields benefit from armor ratings from the modular armor it is placed in. (This does not work for vehicles, oddly enough)

It used to be, shields take 100% damage from everything, but once ...

That is interesting but are the defense values of the modular armor interfering? I dunno how the calculations are done/applied but this is my guess.

When the energy shield is up you are using pure energy to deflect the incoming damage.
When the energy shield is down your are taking the "leftover ...
