Is the Epic feat Master of Spellvials a waste of time? I have played lots of Alchemists and didn't ever take this feat, but I was looking at an older Poison Nuker build that had the feat taken so I looked at it and it seems really powerful and I took it this life at 24th level. It didn't seem like I was doing more damage than I would normally do, but my spell levels are mostly capped at 25 rather than whatever it normally is, even 1st level spell Empty Bottle. Looking at more recent Nuker builds I don't see that feat used. Is there something that's not working right with that feat?
