Summary

Mods "[MoM] Add pseudo tool to nether crystal outcroppings, add that tool as a possibility to contemplation recipes"

Purpose of change

If you can meditate using a matrix crystal as a focus, should you be able to meditate among a cluster of black nether crystal? I think you should.

Does this have the possibility to lead to some...odd outcomes if you're unlucky? It might.

Describe the solution

Add a pseudo-tool to nether crystal outcroppings and add that pseudo-tool in as a possible tool for contemplation recipes.

Also add a recurring EoC that checks whether you're hanging out at a crystal cluster for long periods of time (done by the recurring EoC firing off another EoC that checks if you're still there) and can give you the Observed effect, or if you do have the Observed effect, cause some shenanigans (shenanigans to be determined).

Describe alternatives you've considered

Testing

Meditation at crystal clusters works. The EoC to check if you're near a cluster for a longer period of time also works and can give you the Observed effect. At the moment, I've only applied a single shenanigan (hearing sounds)--future PRs can expand these the way Nether Attunement is being expanded.

Most of the diff is splitting off Observed effects into their own file.

Additional context

[MNG-cataclysm]

Maybe the shenanigans in question could simply be some mid to high-level Nether Attunement affects? I'd be simple enough to hook together the two effects.

[Standing-Storm]

I had the idea for some separate conditions to give Observed its own identity since right now it only gives you bad dreams (hearing voices, sleepwalking, hallucinations, etc), so some of that might get implemented here.

Hints for adding a new word to the dictionary

• If the word is normally in all lowercase, such as the noun word or the verb does, add it in its lower-case form; if the word is a proper noun, such as the surname George, add it in its initial-caps form; if the word is an acronym or has special letter case, such as the acronym CDDA or the unit mW, add it by preserving the case of all the letters. A word in the dictionary will also match its initial-caps form (if the word is in all lowercase) and all-uppercase form, so a word should be added to the dictionary in its normal letter case even if used in a different letter case in a sentence.
• For a word to be added to the dictionary, it should either be a real, properly-spelled modern American English word, a foreign loan word (including romanized foreign names), or a foreign or made-up word that is used consistently and commonly enough in the game. Intentional misspelling (including eye dialect) of a word should not be added unless it has become a common terminology in the game, because while someone may have a legitimate use for it, another person may spell it that way accidentally.
