I thought I had scoured most of the posts for information about invisible buffs but I had missed post #342 that mentions this. Not everyone has the time or wherewithal to read over 500 posts. Nor is the original post updated with confirmed, relevant information on a regular basis. That bit is unfortunate seeing as most class threads (in other games, personal experience only) tend to do this and it’s exceedingly useful for regulating reposts. No reason to be short towards someone either way.
I do like your idea of Paladin C1 fitting in most builds. With something like an Arde dagger even the skills that don’t scale with INT (smite) can be fairly useful. I found this out when I mixed Monk with Sadhu. With 0 stat points in STR my double punch still hits for about 1k. It’s useful for picking off single mobs or leftover trash after I get knocked out of OoB.
