It is a pity that the Gargorites will again remain the loser. I just saw the number of acts directly or indirectly strengthening the robots of the pirates and the dosihpor is at a loss how they have not cut out all the living things yet and did not plunder all the dead. There are fewer reinforcements only in the inchlings. But how are the Gargorites still survived? Considering that for the pirates the murder of gargorites in their lair has long become the usual entertainment.
The obvious answer is "you are underestimating the Gargorites." Between the fact that they have been directly strengthened already (with the benefit of Derivative Improvement amplifying that strengthening) and the fact that they were worthy rivals to the Pirates from the start (remember, Gargorites were a Great Act too), the Pirates
can't just roflstomp them; hell, I wouldn't be surprised if they were currently
at a disadvantage since this is the first turn where we're trying to directly strengthen the Pirates instead of introducing an unrelated treasure that the Pirates happen to benefit from.
On top of that, the Gargorites have had Ages to fortify their lairs; the Pirates may have numbers, but they still need to get through all the traps to get at them.
...In fact, evidence that the Pirates might currently be at a disadvantage: The Gargorites nearly
destroyed the Lady Luck when they were introduced; I suspect that if we hadn't managed to get Great Act on both it and the Pirates they wouldn't've been able to defend themselves. And, as mentioned, the Gargorites are currently one of only two beneficiaries of
direct strengthening (which, here, counts for a lot more than an equivalent Act that strengthens a faction as a side-effect).
And all that's failing to mention that
the Gargorites have been indirectly strengthened too; if nothing else, there was that "incarnated wealth" thing that actually taught them to trust, which means they are permanently banding together into tribes... and their solitude was probably the main reason the Pirates were keeping up so well.
tldr: Gargorites are surviving because
they are currently winning.
