While you may be tempted to only cast high value spells during this, it is perfectly acceptable to only cast one and then fill the stasis with 2 medium power abilities. Generally, you will want to aim to get Spiritbloom at the very minimum into your stasis window and then also try to aim for a Dream Breath cast. Your last ability or two can simply be Emerald Blossom. By doing this, when you reactivate the ability at a dangerous point, you will heal up your allies extremely quickly, faster than any of your other abilities. You want to use this as much as possible and plan for damage ahead of time to make challenging moments nonexistent.
