I find the item description of Treefolk's Fury +5 in the game is different from that in the read me file.
Through test, I find the descripiton in read me file is accurate. Hope it can be modified in the game.

And the description of Death of A Thousand Cuts +4 in the game is also different from read me file.
In the game, it has -4 penalty of save throw vs death while in read me file it doesn't.
I cannot test which one is corrent (and i think read me file is correct once again).

Can someone convince me which is correct?

I've made some fixes in v7 to the new items, TF+5 is one of them, so that is possible.


Well, technically you are both right and wrong. DoTA had some issues with the saving throws (which I've fixed locally for v7) so the description might be misleading. However, I don't really see any difference in how the description is worded in the current master branch version of IA.

So does DoTA have -4 penalty or not？
It should have according to the description in the game while not in read me file.

It does.
