Tales of Arcarum is THE event for farming Replicard Sandbox. Let me run you through it real quick.
Tales of Arcarum takes place entirely within Replicard Sandbox, so it's worth having a full setup for it already.
Note: If you don't already have an Evoker character, please skip this section, as you will not be able to fully farm this event beyond the initial missions.
Tales of Arcarum significantly boosts your strength and item drop rate within Replicard Sandbox, making it a perfect time to farm any materials you need from there.
As Tales is essentially just a "drop rate up" campaign for sandbox, to farm this, you just have to farm sandbox. I have a guide on this.
Start by looking in the missions tab and clearing all the missions. This will upgrade your Expedition Rank, giving you increasingly stronger buffs within Replicard Sandbox.
After this, you'll want to farm out Medals from Sandbox - any content will give you medals, even if it doesn't match the Evoker's element. (e.g. the one starting today features Alanaan, meaning Fire-aligned enemies will drop extra Medals, but every enemy will drop them nontheless)
Medals should be used to purchase every single item in the shop, prioritizing:
Everything in the shop is worth it, and the Medals are reasonably fast to acquire.
Once enough medals are acquired, you'll unlock parts of the event exclusive story. Clear the story to the end to gain a bonus pose for the featured character.
