Bestial Skin does nothing?

I have Beastial Skin on a corrupted amulet and see zero changes to my evasion rating when it is equipped or not.

I have the same issue but my amulet and armour are not corrupted.

Same here

Same here. Body armour and amulet do not corrupted

same here

I would like to ask a question if I may.

When you activate Bestial Skin, do you just go and look at the evasion number on your chest piece?

If that is all you look at, you are looking for the answer in the wrong place. The increase does not directly raise your evasion number on your chest piece. You have to go to the Character Screen (where your life, and mana are shown), then scroll down til you see evasion, now put the amulet on, or take the node its self, and look at your evasion on the Character Screen, it should have raised the evasion by the number that your chest piece has on it.

I do hope this information helps out.
