Arcana Quest

Replaced Tough as Nails with Simple Difficulty since it is still being maintained and adds a few additional options over TAN. 

Made some adjustments to temperature that should make it somewhat easier to survive in more extreme climates. Depending on the season and other conditions, these regions will still be dangerous, but temperature shouldn't fluctuate as extremely now.

Changes to the thirst and drinking non-purified water. Now in addition to gaining the thirst debuff, there is a percentage chance that drinking unclean water can make you sick, causing a damage over time effect (about a quarter of the rate of the poison effect) and also more rapidly diminishes hunger level.
Nerfed Grimoire of Gaia mobs. They now will deal 25% less damage and have on average 75% of the health they used to. They also should spawn somewhat less frequenlty.

Buffed the food levels for cooked meats. They will restore 2.5 shanks of food and an equal amount of saturation. This was to keep the higher tier Pam's foods still relevant, but make early game survival more viable when using meats as a food source.

Temporarily disabled the structures from Ancient Spellcraft. I'm planning to add some structures that will replace these.

Renamed Pam's Harvest water item to Fresh Water since Clean Water is used in The Betweenlands. Added a tooltip that says to craft them with a bottle to get drinkable water.

Added a new item that is available in creative only currently but will be added to certain higher tier loot pools later: A Village Locator, using the item will instantly teleport you to a village that you've never been to.

Adjusted rules for underground mobs. They won't as dramatically increase in difficulty. They will now increase in three tiers as you get progressively deeper. Tier 1 begins spawning immediately under at y60 and is only slightly stronger than normal, tier 2 begins at y45, and at y30 the mobs that spawn naturally will receive significant increases to damage, health, and speed.
