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

[Cleftobismal]

Synastry should be treated like divine seal and used as frequently as possible while planning it's availability for healing intensive mechanic damaging abilities.

*Whistles

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.

*Blows on Tissue

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.

*Wipes Nose

If you are confident you can heal mechanics like nidhogg ex and a12 swithout synastry then do so. It's wise to save it during a "Oh Sh-" than using it all the time. I grind my teeth when I make that mistake and know I could of saved the party if I saved Synastry for something I really needed it for.

Not sure if were on the same page.
