firstly, Briar says this
Defeating a bloom or slaying a 17th-level or greater monster from the First World—including all creatures closely associated with a bloom—gives Briar a Sharpness Point.
so, what if the AP says that defeating the 17th lvl creature ends/defeats the bloom, does it gain 1 or 2 sharpness points?
secondly the end of ch 10 pt 1 says
One or more blooms remain active: Nyrissa can attempt to take the Stolen Lands out of the Material Plane and into the Apology. ...If she’s successful, consult Concluding the Chapter on page 477 for the ramifications of this disastrous development.
looking on pg 477, it only details what happens if she dies...nothing about stolen lands being take out of the material plane...
if there's 1 bloom active it's 10% chance, then +10% chance for each extra bloom active, there's 3 on day 25-28, and the check is done on day 30, so not that unlikely 1 is still active...i may be missing something that's said in the rest of ch 10, as i've not read past pt 1 yet, but it pretty clearly says the text should be on that pg...
thirdly, the Notice Bloom reaction has them make an exploration check if it's in an unclaimed hex, which is quite possible, given some locations are as vague as, "a mountain hex", "a hill or plains hex" etc - my PC's kingdom is untrained in exploration, so has a +6 i think (might increase slightly by then [currently lvl 14], but they're unlikely to get trained), the DC is 35, so they CF on anything but a nat 20, which is then a success, which then leads to the above flat check due to a bloom being active on day 30, being much more likely to occur!
1) Looking at the blooms, some are made of creatures below 17th lvl and some above.
If a bloom had 4 14th lvl monsters, then Briar would gain 1 points.
If a bloom had 2 18th lvl monsters, then Briar would gain 3 points.
If a bloom had 1 18th lvl monster and 2 15th lvl monsters, then Briar would gain 2 points.
2) I think that it's referencing the wrong section. In Appendix 1: Beyond the Campaign, there is a section "What if Nyrissa Wins?" pg 505 which has text about ramifications of taking the Stolen Lands.
3) The first bloom is probably only going to be spotted by Notice Bloom, but on Day 3, they should be warned by Fey about the blooms in general. From that point on, the PCs will probably start using the Bloom Watch downtime activity. Since that has so many different skill options, it should be possible for each of the PCs to have a chance to notice the later ones.
The 2nd last one is at the realm's capital that will be notices the same day, and the last one (if sent) will probably appear at the PCs location and they will notice it.
Since the location of the blooms is entirely at your discretion, you could mix in hexes (which would be noticed by Defense instead).
hmm, so if nyrissa succeeds that flat check...the AP is over as written...that's not great! i run APs cause it's all written for me already, i'm not gonna suddenly hombrew my 1st campaign at lvl 17-18+ if she succeeds that flat check...
