Rare Maven invitation a must?

ugh. I just did a 10-boss Rare Maven invitation. I failed it in the end. Do I have to do it "rare" to unlock the 5th passive point? Can I scour it to "white" next time I get witnessed 10 times?

Yes, you can scour maven 10-way invitation.

You got the right idea - do it white the first time for each region so you can get the atlas passives; and on the next one, do it rare if your build is strong enough. Same goes for the hidden atlas passives as well, like the Formed, Feared, etc. Better to just do it white the first time.

I think higher rarity invitation can give you better loot specific items such as higher tier craftable watchstones, unmaking orb and maven splinters.

If you're on trade league, you can buy these invitation but you still have to let Maven witness the bosses again before you can use the invitation.

ugh. i wish I found out this. I failed it after grinding 10 witnesses. Thanks for letting me know. I will make it "white" for all invitations. As for the drops from the Invitations, I've never got anything good except for "refund orbs".
