Note that although Guardian of the Crystallizer enters play exhausted, it still enters play engaged with the investigator who drew it.

When an enemy card is drawn by an investigator, that investigator must spawn it following any spawn direction the card bears (see "Spawn" on page 19). If the encountered enemy has no spawn direction, the enemy spawns engaged with the investigator encountering the card and is placed in that investigator's threat area.

This is probably the hardest of the cycle to make work. However, there's one new tome in TSK, grim memoir, that works pretty well with this as it's both expensive and requires multiple skill tests. Using in a Daisy deck that also managed to find another good tome as a story asset.

Forgotten Age isn't everyone's favorite campaign, but it's worth noting the original Curse of Yig story was based in Oklahoma. So the next time you're wishing you weren't lost in the jungle while Poisoned and covered in vines, just remember: you could have been stuck in Tulsa.

This optional boss rewards 5 XP for killing him, which nice if you can juggle the vengeance needed to get here. That said, Yig has a decent bit of health. I recommend making use of the discard ability on Knife to get an additional damage in while fighting him.

Interesting note: Rift Seeker has Cultist, so once it's shuffled in you can use it as a target for Mysterious Chanting that doesn't speed up the doom clock the turn it enters play.

Aside from that neat little interaction, Rift Seeker is honestly pretty basic; no Hunter if you decide to evade it and leave it behind, no "Spawn:" instructions spawning it at a different location preventing you from dealing with it, not even Retaliate in case you fail the 3 (or 4 once The Entity Above, The Entity Above, or Swallowed Sky enters play) test to hit it. Yes, it does have the Parley option, but that's a trap, paying a high cost (2 horror and 2 doom) for something that's honestly not that difficult (defeating a slightly tougher Ravenous Ghoul). Assuming you don't draw the against it, you can fairly safely treat Rift Seeker's text box as blank, except for Traits: those actually make it interesting, allowing you to fish out a (moderately) tougher Cultist with Mysterious Chanting in exchange for no doom entering play.

Dumb question: Where does The Man in the Pallid Mask go after he's defeated? He's only earned as a weakness during scenario resolution, but he has a player card back; does he just get added to the defeating investigator's discard pile?
