Alright, this guide will not only attempt to fill you in on how u do mystic tome (its actually so easy.. -.-) , but it will aim to eliminate the frustration you get when u get fake pills(talchi) as i’ve observed from statistics, that the answers are not really random.

first of all, the quest…

Quest Starter: 
Eldest Matchmaker in Sunstream
Required: 
Kill 99 predatory hornets in Jadeon
Reward: 
1 of the 3 Mystic Tomes

the tomes…

Flying Fairy: 
Go to any skylords
Dream Seeker:
Find the Dreamland Vendor either strolling around in Sunstream or in Baxi eatery in Skysong
Riverside Immortal: 
Go to the Sky Dweller either by flying on a skyblade or portal charm

now, here comes the important part…
answers… (Answers on sky dweller and skylord are still assumptions, that worked for me and all my alts at least…)

Dreamland Vendor: alright, for DLV, its easy… hand in the tome and talk to her again…

Riverside Immortal: Check what time of the day is the game in when u are answering, if u see the sun shining bright pick ‘Hope’, if the sun is not there pick ‘Despair’ (Still under research also… check back for more info)
