Apprentice's Card

Apprentice's Card is a Star Blessing.

Description

Every 4 Starter Die you play, deal 10 Purification to all targets. This counter is kept between battles.

Moonie has the most number of possible interactions with this Blessing, having Stellar Cleanse and Ingenious Touch to interact with Purify 1 synergies, in particular, Insight allows her to play more Starter Dice than average by transforming them into a lot of draw, which, in combination with her Draw 1 Virtue allows her to move through her Astrarium very fast.
Hevelius follows in close second, having Perfect Repair to potentially draw 8 dice at once, and additional reliable draw provided by Clever Scrapping. Early on, this can be enough to handle most battles by sheer number of dice played to trigger the Area Purify effect.
Sothis can play the same die repeatedly with Sands of Time, allowing extra increments of the Blessing within a turn.
Orion's Magistral Replication can be used to generate many copies of Starter Dice in a battle.

v1.2.313: Buffed the cycle length from 6 to 4, and the Purify amount from 6 to 10.
