WotC put up new errata. They've nerfed quite a few items, including the Cloak of Distortion.
So my questions are:
1) Do the errata automatically apply in LEB?
2) If so, can PCs swap magic items out?
In the case of the Cloak of Distortion, it allowed my PC to not take leather armor. She had an AC of 17 at close range, 22 at beyond 5. Now she has an AC of 17 at close range and 18 beyond 5. It really wipes out the concept of a PC that is defensively weak in close but strong at range.
Note: same level monters average level+5, so she went from getting hit on an 8 or a 13 to an 8 or a 9 (not even taking into account higher level monsters).
