Alchemist's Pact is a type of Gem Set that gives you 300 Gems upon purchase and a bonus of 100 Gems and 3 Skip Tickets every day you log in for a duration of 30 days.
The first 300 Gems will automatically be added to your Gem count, which you can view on the Home screen.
To collect your daily 100 Gems and 3 Skip Tickets, go to Home > Milestones > Daily > Alchemist's Pact Daily Bonus. To claim all bonus Gems and Skip Tickets, please repeat this step each day for the next 29 days.
You must claim your 100 Gems and 3 Skip Tickets daily, as they will not be rolled over for any missed days.
