Thanks for catching that! And let me know how GMing it goes!

Health is dependent on what Looks you have equipped! Page 40 is where that's mentioned, and then the HP stats for each type of Look is in the Looks section. 

I appreciate the comment! Each player should be starting with three different Tier I Looks at creation so they should be starting with at least some HP ( I suppose there is a chance to roll three accessories which would be some bad luck there!). If there are repeats like that then rerolls are absolutely okay (and honestly, if the players wanted to take the tables as more of suggestions that's fine too).  I'll make sure to add a note in the next revisions pass about rerolls for starting Looks. 

The latter (so two rounds at II and three at tier III). I think a better wording would be "lasts a number of rounds equal to Tier" to avoid any confusion. Thanks for pointing that out!

I honestly don't remember if I had meant to include a Flow cost for Starfall or not, but I think since you have to have two other 5 slot tokens equipped to even use it, let's go with no Flow cost to activate it!

Ooh! That's a good question and not something I had considered! There is currently no "Tier 4" level to upgrade something to, so I could see maybe it becomes a "buy-one-get-free" sale (two items at +1 Tier for no extra cost), maybe you get an extra tag on that item, maybe it can count as two Brands (like how the Looks the Watchers can drop work). I'd pick something that seems fun and rewarding and that makes that Look feel particularly special!

They have access to any desperation dice they've unlocked, and can use as many as they want! So the more ticks on the Countdown Timer, the more DD they could use on any given roll, but the more likely they are to attract the attention of the Watchers. Which is generally a bad thing (but can be a fun thing).

That's the limit on stealing an elemental tag per scene!

An action roll is basically anything that would be risky or carry consequence. That can includes using a Token outside of the normal effects outlined in its description. If a Token says it deals damage, you don't need to roll to deal the damage, just pay the Flow cost.
