This post appears to be accurate. For my successful playthrough - second attempt - this was playing with a Silver/Blue dominant tide, Aligern liked me, Matkina was forgiving, Oom was I don't even know. Hard save after the first Dracogen conversation in the bloom. I failed the initial concentration check.
1) Convinced the vendor lady to go back into the Bloom
2a) Got Inkpot's quest
2b) Destroyed Ioxu's machine, then Ioxu and the Construct. I believe it is critical that you do this FIRST, as attacking Ioxu first seems to not give you the right option to destroy the machine afterwards. I didn't see Maws spawn when going for him first either. Also, didn't hit the maws
2c) Turned in that quest
2d) Killed the two vendors
2e) Opened the cyst but did NOT take the hilt
3a) Murden tunnels - paid them to move aside
3b) Lied and led the thugs to their death
3c) Opened the treasure room by pushing the guy back in to feed the maw, and looted everything including the cursed shins
4) Slept at the shrine to drop the debuff
5a) In Little Whatever, attacked the thugs immediately, sided with the mutants
5b) Fed Wondor to Aen-whoever
5c) Did the quest involving the mutant in the tank, to feed the prisoner to the maw - but stopped there
6) In the upper right area, intimidated the guard captain to enter the maw
7) Blasted through the Ascension - didn't speak to anyone except the crystal, passed checks for the Annulet, pased check on the way back to avoid combat
8) Bloom tongues fed on me, took control, absorbed memories of the dead. This is critical, it will specifically say the Bloom approves of your actions if you chose the right one.
9) Turned in the Annulet
10) Fed Matkina to the maw at the shrine. I was in a hurry
11a) Stealth backed away from combat
11b) Bloom tongues fed on me, took control, forced combatants elsewhere
11c) Searched the construct for sealant and sealant
11d) Spoke to both people (not the murden) to sacrifice the dude and open the maw. Did not enter it
11e) Use the sealant items to open the whirlpool, jumped down, took damage.
That's ALL I did. If it's not above, it wasn't done. No slavery, no excessive murder, one solitary crisis, didn't touch Waits-for-prey. If done right, you will get a message saying the Bloom welcomes you when you stand up after going down the whirlpool. If a crisis initiates, it's no good.
