That is shorter re-deployment time. Can't tell you what attack cooldown does though. As idk what attack it's lessening.
Well it's either characters' attack CD, or your clicking CD. At some point I noticed that my empowered clicks were charging up real fast, though it also could be a buff from goblin mage. I can try to upgrade attack CD further and see if my characters' CD is shorter. But man will that cost a lot of money, it already takes me around 5k currency to upgrade it further. I wish increasing lv. would also increase the amount of moni you would get from a stage, not just upgrade items
OK, I've tested this thing and it actually buffs char's attack CD. As you can see on these screenshots, my minotaur had 5.8 seconds CD at 76% buff. After I've upgraded it to 67%, the same minotaur's attack CD became 4.9 seconds, which means that it's CD decreased by almost a second. It's not really easy to see the numbers on mobile(I hope developer will fix thix), but if you look close enough you would
probably see it.
I see. Doesn't feel as if my army is attacking any faster than it has been. But since most of my focus is everywhere else. I would imagine it's hard to see minor differences like those. (Unless you fully max it out and you just watch a minotauress do a 6-hit combo in 2 seconds flat. which would be possibly funny to watch IMO.)
