Clerics: Invincible or Bless first?

[Amy]

Now that Invincible got a massive buff, I've been wondering what a Cleric should max first. Bless for the +20 accuracy or Invincible for the -30% physical damage? What would parties find more valuable?

I'm thinking Invincible, but I'm honestly not sure.

Still heal to level faster, then if you really have warrior friends then accuracy, invisible is not viable -30% dmg reduction as you can heal them anyway.
Just my opinion though

Invincible would be great for partying with a low defense class training at golems or something since they would really need to defense then... But a cleric at golems...?
