Does "Attack" knowledge help in POP / SH / Fury Towers? Or is it only "Fortresses" knowledge?

"Fortresses" knowledge helps on Fury Towers as well I guess.

I had the same question, was not entirely sure about it, but I was right in the end. This is the official response from plarium:

"The Attack and Defense trees improve your Troops' statistics no matter where you fight. However, Fortresses tree is only useful when you are attacking or defending a Fortress. Please don't forget that the amount of bonuses may vary depending on the tree. Also, the upgrade cost for secret Knowledge starts at the same level in all categories. After the first upgrade of secret Knowledge in one selected category, the cost for secret Knowledge in the other categories increases. Therefore, we kindly suggest you to choose wisely."

The Secret Knowledge is the biggest rip off that Plarium has ever perpetrated on it's players.

I would like someone to explain to me what difference exists between games on Plarium, Mac and Facebook. Every day you try harder to play better and every day you get less of a reward.

Based on this and your other post.

I think that.

# You have found that improving levels or skills has had little effect on your success,but also made it harder to reach the events levels the game asks. 

# You are asking if you would have more success with your game if you were to play it through another device.

# The answer is probably no, but to confirm this you would need someone who is playing the game  on Plarium.com, Mac and via Facebook or whatever other medium is possible,and I think that is most unlikely.

There is the assumption that by doing the next level, it will be easier from there on, but the next level takes more than the current level, e.t.c.

All these types of games, even those that are completely free to play have increasing difficulty as the level increases.
