Pros:
- Provides 1 additional XP after each scenario (duh).
- Doesn't kill you outright after being defeated unlike Charon's Obol.
- Is a Science asset, so can be taken on Kate Winthrop alongside the usual Mystics and investigators with level 0 Mystic access.
Cons:
- If you're defeated once, you get Homunculus'd - meaning you can't change your deck, you get a load more basic weaknesses, and your statline will make you want to cry.
- Two strikes and you're out, if you're defeated again you're killed.
- May encourage cheating: "If I hadn't drawn the I wouldn't have been defeated, so let's ignore it!"
Deckbuilding Tips:
- Pairs well with Arcane Research and Down the Rabbit Hole - synergising by offering more XP.
- In the Thick of It is less worth it, as in 3 scenarios you'll have earnt that XP back from the Great Work, and the trauma puts you at risk of Homunculus-ing (I know Arcane Research provides trauma as well, but Arcane Research has a much greater pay-off).
- For Dexter, Sefina, Charlie and Lola, it pairs well with Charon's Obol - as realistically the Homunculus is annoying enough that death may be preferable!
- Transfiguration can un-Homunculus you for a scenario. Obviously you need to buy this before you Homunculus as you can't change your deck at that stage. Charlie and Lola are good Transfiguration abusers in particular given their wide card pool.
- You'll want to consider how many upgrade points there are in your campaign, and so how much bonus XP you'll be earning. I usually use 8 scenarios with 7 upgrade points as my rule of thumb for XP-boosting cards (with some luxury XP upgrades in your back pocket if the campaign goes on longer).
I just posted a Dexter deck today using both this and Charon's Obol (on the 1st April no less...). Generally as mentioned above you should think out your upgrade path for a Great Work deck before starting a campaign, as analysis-paralysis is common if you're awash with XP. It's also good to think about your backup plan should your investigator die (Ascetic decks are a good tool for this, I posted an Ascetic Kymani deck in the past month with the goal of replacing killed investigators). That's all there is to say really - watch out for the Homunculus!
