I'm talking about expected value.
Let's say luck is zero. For this case, let's take the creature's damage as x.
Then, if a hero has 5 luck points and no special skills, there is a 50% chance that the creatures will deal x damage. With a 50% chance, the damage will be 2x.
What is the expected damage with 5 luck points? That is, what is the average damage? To do this, we take the damage from each attack and multiply it by the probability of it occurring. The result is 50%*x + 50%*(2x) = 1.5x. In other words, the average damage increases by a factor of 1.5 with 5 luck, relative to an unlucky creature, all other things being equal. It's easy to calculate that with 3 luck, the expected value will be 1.3x, and with constant luck (without the elven skill, which is, of course, incorrect), the average damage will be 2x.
These 2x should be compared with 1.3x or 1.5x, but not simply with x. Because a second before we took the true luck value, the damage was already increased relative to the base value thanks to the upgraded luck skill tree. And the increase relative to it is smaller.
Effectively, we can say that true luck makes the "expert luck" skill useless (as it becomes obsolete, replaced by a stronger effect).
In contrast, the dwarven absolute defense does not make anything we upgraded for it useless. It does not require, for example, the "deadly misfortune" skill in the luck tree to work (reducing enemy luck by 1). Therefore, it can be honestly said that it simply halves the enemy's damage. Nuances are, of course, possible – for example, with this very elven luck, which slightly changes the expected value coefficients, but in general, that's how it is. If absolute defense were also convenient to upgrade in terms of the strength of other skills and the chances of obtaining them (at least, it wouldn't require a summon with 4% and missing spells in the guild), I would say that it is much more overpowered.
