Hello, the Corbin the Venerated companion bonus power from Echoes of Prophecy is not granting any Item level. Mine is at mythic grade (I upgraded it), it should grant 750 Item level but actually doesn't. The bonus power itself is working.
I can confirm this bug. Info says it gitves item level 300, while it is supposed to give 500 to combined rating. As a legendary companion, it usually should be item level 500 on legendary level and give 500 to combined rating.
But now (on legendary level) it gives 0 (Zero) to item level and 500 to combined rating.
So: a bug (or even 2 bugs). Until this bug is fixed, it may be nice, though - for people who struggle to get their rating stats up. 0 additional item level, but the combined rating raise of a legendary (or, if upgraded, of a mythic) companion is surely a nice boost with no raising of item level at all. Especially good for scaled content. Again: only until this will be fixed eventually.
