Proof of Myrrit

• 
  
• Vertical Anomaly: Kill the adds. Use [spell=400132] and [spell=400143] to destroy [npc=205559] and [npc=205563]. [spell=400130] on the pressure plate. Enter the central bubble to swim to the moving bubble to swim to the bubble containing the [object=397993]. Loot the [object=397993] and use the [item=203655] to open the [object=401295].
• 
  
• Scratch and Sniff: [spell=400131] until [npc=201426] says: "I smell something briny over here..." (Mine was at 54.58, 51.25). [spell=400132] and [spell=400143]. Kill and loot [npc=201747]. Use the [item=205277] to open the [object=401310].
• 
  
• Successful Interventions: Drink the [object=402597] on the table. Talk to [npc=205080]. "Ask about Ralph." to [npc=205088] until you find the one that says "I'm Ralph. Either ye believe me, or ye don't." Then "Point out that this is Ralph to Mr. Sunflower.". Loot [object=402149] from the table in the corner.
• 
  
• Your Weight in Gold: In the cave with gold and pressure plates, sniff out [npc=205330] and let him use [spell=411045] while you're on a pressure plate to put [npc=205334] on the plate (be sure to move away once the golden pool is showing on the plate). I think you only need 3 pressure plates pressed. You can put [npc=201426] on one, stand yourself on another and use aforementioned technique for the third. (I used the technique on 3 plates when I noticed the door was already open).
• 
  
• The Living Drill: Use [spell=400132] and [spell=400143] below an orange cloud to spawn and kill [npc=205613] 3 times. Kill [npc=204434] to loot [item=205941]. Use [spell=400131] close to the pool to [spell=400143] up the [object=402534] ([npc=201426] should say "I smell something un-wormlike"). Loot.
• 
  
• Making Scents: DPS [npc=203606] until it's immune. Use Smell and read the text. Click the orb matching the message ("Is that burned charcoal I smell" = fire). DPS [npc=203606] until dead. Loot.
• 
  
• Heart of Iron: Kill [npc=204426] to get the [item=205939]. Use [spell=400131] to find "Wait! There's LESS burning smell here!". Use [spell=400132] and [spell=400143] to dig up [object=402533]. [spell=400130] and open [object=402533].
• 
  
• Frostfire Finesse: In the cave with the Fire Charge and the Frost Charge, click the Fire charge and put [npc=201426] on the Pressure plate of the Frost Charge to pick up the [item=206001]. If needed click the Neutralizing Charge to remove any remaining [spell=411698]. After that click the Frost Charge and and put [npc=201426] on the Pressure plate of the Fire Charge to pick up the [item=206002]. Once that's done, use [spell=411729] to combine the keys to the [item=206000] and open the Frostfire Cache.
• 
  
• Flapping and Screaming: In the cave with the crystals. Pick up the [object=402580]. Use [spell=411283] to capture a [npc=205417]. Stand close to a crystal so the captured bat can shatter it. Repeat until you find the [item=205969] (mine was at 54.99, 48.94). Unlock the [object=402595].
• 
  
• Element Whispers: Go right and use [npc=201426] to dig up cracked tablets in front of each pilar. On each tablet you'll find a cardinal direction and an element mentioned. Go back and now take the left path. West(left) of the [npc=204800]: Choose earth, North(behind) of the [npc=204800]: Choose fire, East(right) of the [npc=204800]: Choose air, South(in front of) of the [npc=204800]: Choose water. Talk to [npc=204800]: "Can you check to see if my pattern is right?". Kill [npc=204800]. Loot [item=205689], jump down and unlock [object=401296].
• 
  
• Those Rascally Worms: Talk to [npc=204587] to make a deal. Use [npc=201426] to dig up [npc=203850] ("Phew, that's worm-stink!") and [object=398116] ("I smell something un-wormlike") to collect 6 [item=202180]. Talk to [npc=205267] to feed it. Click on the basket [npc=205267] was on to collect [object=401242].
• 
  
• Sneak and Sniff: In the cave with bats & worms you just need to go pick up the [item=205412]. I'm not sure if something I did made it spawn, but it was certainly easy to miss. No need to kill the bats nor worms to my knowledge.
• 
  
• Thieving Critters: Go to the room with the [object=400987]. [spell=400132] at the entrance of the left path. Wait until the orange cloud moves over you and [spell=400143] up [npc=204432]. Kill it to receive the first key. Follow the right path and destroy [npc=204439] to spawn [npc=204435]. Kill it to get the second key. Use the [item=205185] and [item=205186] to unlock [object=400987].
• 
  
• Living Statue: Kill both [npc=201871]. Pick up the Light Etched Key and restore it by putting it on the Etched Receiver with the small orb on it. The other 3 keys can be found by sniffing & digging below stone piles around the cave. Once the 4 keys are restored, click the statue and kill [npc=204419]. Use the [item=205938] to open the [object=402532].
• 
  
• Liars in Light: Stand on the pressure plate next to the Tauren Statue. Talk to the Tauren Statue and select "Choose this statue as telling the truth." Kill the [npc=204430] and loot the [item=205202]. Use it to open the [object=402216].
• 
  
• Liars of Spirit: [spell=400130] on the pressure plate. Talk to the Regal Statue and select "Choose this statue as telling the truth.". Kill [npc=205540] and loot the [item=205990]. Use it to open the [object=402437].

For Your Weight in Gold, you actually need 4 pressure plates. You can use the Buried Wealth to enable two, then Myrrit and yourself on another two :)

For Element Whispers, my elemental/directions were different. It seems as if the tablets you unearth are random. For me, it was Fire/North, Earth/East, Water/South, Air/West.
