Trickster Cleric's Lv1 feat- Blessing of the Trickster is a pretty useful feat that allows you to turn your Rogue into a ghost, or your clunky heavy armor fighter into... well, not an elephant walking on bubble wrap.
The thing is, while this is a really good ability, it's also the only thing the trickster cleric gets at Lv1. Other cleric domains are getting feats like heavy armor and martial weapon proficiencies, on top of cantrips or skill proficiencies.
Therefore, I don't really think the feat can really afford the nerf that came with adding concentration to it. It removes it's ability to be used in conjunction with say guidance, if you want to be kind of really good at sneaking; or pass without a trace, where you turn your entire party into a Dai Li hit squad, by removing your fighter's stealth disadvantage and giving everyone +10 to stealth.
It's supposed to be an ability to highlight and compliment all the things you can do well as a subterfuge master, not make you chose between it and something else. Please consider removing the concentration condition from it.
