Poetics

[ItMe]

I read there is a weekly limit of 450...

Poetics do not have a weekly cap.



In this game there are three kinds of tomestones:

The most recent kind (this is the only one with a weekly cap), which is currently Allagan Tomestones of Revelation.

The previous kind (currently Allagan Tomestone of Allegory)

And Poetics. Whatever you can buy with Revelation and Allegory you will be able to purchase with poetics when they rotate out for tomestones with newer names.
New tomestones are added in with each raid tier, but poetics never cycle out.
