The Wizard101 Test Realm is back online and this update includes the Monstrology system, the new Monstrodome housing item, three new Skeleton Key Bosses, level 118 school pet quests, Aquila fishing, Jewel Vault, new trainable spells, new Castle Magic items and spells, and much more!
Monstrology

You'll begin with a quick training session to using the Extract Animus spells, which apply to damage cards in combat much like other enchantments. Use these enchanted cards during combat to extract Animus. Use Animus to then create Summon Monster Treasure Cards, create Housing Guests for your Castle, or create powerful Expel Monster Treasure Cards for non-boss enemies.
Press "T" in game to open your Monstrology Tome to create and track these new items.
Monstrodome

You interact with the Monstrodome much like you would other housing items. You click on the "Place Object" housing button, place your Monstrodome in your house, click on your Monstrodome, and then click on the Monstrodome icon.
Skeleton Key Bosses
Unique loot is waiting for you in each of these three new fights, if you're able to master their challenges. What new treasures will you find? It's time to face off against the new Skeleton Key Bosses:
- Find Sapoti in the Hall of Doors in Krokotopia (Wooden Skeleton Key Boss);
- Find Captain Hockins in Zafaria's Waterfront (Stone Skeleton Key Boss);
- Find Mirage's Verboten Mimic in Aggrobah near the river area (Gold Skeleton Key Boss).
New Pets
The Arcanum Scholars now have a new quest available to those who are level 118. They will summon you to talk to them in the Arcanum and will send you on a quest to earn a new school pet. Check out all the new pets here!
Aquila Fishing
New fish (and treasure chests) can now be found along the coast of Aquila. Fish up some great rewards and some new friends (like the Spartan Spear) for your fish tanks at home!
Jewel Vault

And there are many more changes and minor updates to the game! Read the complete list of Update Notes for more.
IMPORTANT NOTE: There's a known issue with the Advanced Combat Tutorial from Duelmaster Diego in Unicorn Way for this Test Realm. Please, avoid undertaking this quest for the time being as your game will crash, and your character will be unplayable until the bug is fixed.
