Tool tip Changes for tiamat and lethality items
A couple of patches ago Tiamat was changed from 20 ad to 25 ad and the lethality items had their armor pen lowered. While you get the correct stats when you buy the items the tool tips for these items are their original numbers before the changes.
Q. It says 30 bonus magic damage rank 1 even tho it´s only 10 after the nerfs.
