Tomestones of Verity - what happens in 4.2?

SE post mentions tomestones of Verity will become obsolete but not removed from the game. So what will we be able to do with them exactly? Will we be able to turn them into tomestones of Creation? Or will they just sit there in limbo until SE makes them turnable into Poetics?

We'll immediately be able to convert them by talking to Auriana.

Pre-patch

• Poetics - Permanent pre-SB tomestones
• Lore - obsolete pre-SB tomestone. Exchange for Poetics.
• Scripture - obsolete pre-SB tomestone. Exchange for Poetics.
• Verity - uncapped current tomestones
• Creation - capped current tomestones

Will become post-patch:

• Poetics - Permanent pre-SB tomestones
• Verity - obsolete SB tomestones. Exchange for Creation.
• Creation - uncapped current tomestones
• Mendacity - capped current tomestones

And assuming we maintain the pattern that we've kept since 2.x, in 4.4 any unexchanged Verity will disappear, Creation will become obsolete and exchangeable for Mendacity, which will become the uncapped tomestone, and there'll be a new capped tomestone.

There's not any benefit to holding on to your obsolete tomestones. Exchange them for uncapped tomes right away unless it'll put you over the 2000 cap, in which case spend some uncapped tomes to make room and then exchange the obsolete ones.

Thanks! :)
