I usually save them in case a quest requires them in the future
Junior Alchemist Random drop from Neighbors Laboratory
I've been playing since the first month Charm Farm was live and I don't have a full collection yet. If that gives any indication of how rare these pieces are!
It's possible they drop from your own Lab but I highly doubt it, as much as I use mine I would have gotten at least a few sets by now
Garden Random drop from Crops on your land or at Neighbors
The Garden Collection is one of the most useful, it gives +1 Magical Watering Can which you can use to unwither crops when you're having one of those days & don't want to wait for Water Angels (helpful Neighbors) to come by and water them for you!
Since the Fortune-Teller's House has no current use in the game it's not a very common building for most people to have, which could account for the drops to feel less common than they might actually be
Magic Wands Random drop when casting any Spells
Common Drop (If you use a lot of Spells! and you should!)
Enchant - everything - always! Not only can you get Magic Wands but you will see your Magic Xp, coins and other random drops increase exponentially.
When I needed these for a quest, it seemed like enchanting my Tower of Magic had the best drop rate but you may not have the same results
The name of this collection "Gemstones" is confusing since Jeweler's House also drops Gemstone that is used in Crafting & Building constructions - Just remember the collection pieces drop random but the "Gemstone" (non-plural) drops every-time you collect your Jeweler's House
Rare drop - especially the Burgundy and Talking Hats
This collection is used in some progression Quests so be careful trading them in and try to save at least 10 of each hat in case you need them suddenly, as they are not a quick find when you need them for a quest objective!
After playing all this time, I still do not have a full collection of these. The Lord of the Rings and Game of Thrones seem to be the rarest of the rare
Chimaera Random drop from any Animals fed by you or your Neighbors
Most pieces of this collection are fairly common, the "Head" can take some time when you get a quest asking for it
This Collection gives a lot of Coins & Xp and might be worth trading in now and then
Dragons Random drop from any Dragons fed by you or Neighbors on your land
This Collections drop rate depends on the tier of Dragon that is fed. The higher the tier, the better chance at drops. So an Azure Dragon has better odds than a Green Dragon.
The "Tea Dragon" is a quest objective on one of the Dragon Quests and seems to be the rarest piece to get, but keep at it and eventually you will get it!
This is one of the better Collections to trade-in. It takes 10 Magic Dust per trade-in but gives more Xp than any of the other Collection Sets. I trade mine in often and just request Magic Dust when I run out.
The "Fall Enchantments" only lasts 10 minutes so it's a great Spell to use when a quest objective asks you to "Enchant Shmoos" - They will only be zombies for a short period and can get back on task faster
Well worth the price of trade-in
Winter Random from any item showing here: Snowbank, Snowflakes, Puddles & Snowman
The "Winter Enchantments" only lasts 10 minutes so it's a great Spell to use when a quest objective asks you to "Enchant Shmoos" - They will only be zombies for a short period and can get back on task faster
Well worth the price of trade-in
Spring Random from White or Blue Snowdrops on your land or at Neighbors
The "Summer Enchantments" only lasts 10 minutes so it's a great Spell to use when a quest objective asks you to "Enchant Shmoos" - They will only be zombies for a short period and can get back on task faster
Limited Edition Collection - No longer Available unless you completed the original Summer Fishing timed quest
This is without a doubt the BEST of all the Collections - trading in 3 Magic Dust for 1 Nautilus is insanely good!
Unfortunately the Pond was only available during a short Timed Quest in June of 2015. We've asked many times for them to bring it back but so far no luck. Hopefully in the future they will revive some old quests, including the spectacular Pond!
If you don't have the Pond, ignore this collection.
If you do have the pond, run it often and get those Nautilus in pens - the quickest way to get rich in this game!
