First time playing Astrologian... need some advice/tips

[Cleftobismal]

what's your guy's opinion on synastry? tbh i kinda forget about it quite a bit unless it's an emergency. i've recently moved my abilities around and got synastry to a more readily accessible spot. so now i've just been kinda using it whenever. idk if it's better than lightspeed for emergency heals, but the 20% potency increase is nice even for aoe.

Depends. If you know you can use it a few times before a boss, it doesn't hurt. It's also nice to use if you have another target that keeps getting pelted.

I mostly use it though in one of Four situations:

Burst heal a tank from rapid Tank busting damage.

Where burst aoe heal is required. (Sophia EX Aoe spamming 4 times on party members who are affected by vulnerability stacks)

Popping it on a tank while I save a healer trying to dodge so the tank won't miss out on needed hps.

Making the regen ticks stronger on Dirunal regens and Collective unconscious when it's needed.
