training seals from boxes?

Confirmed, you can get as many medals as you want from this.

Where do you trade multiple medals in for a coupon?

Or, if that isn't possible, why would you want multiple medals?

You get multiple medals, which can be exchanged for Transformation Medal Coupon thingy, not another Joe Coupon. That was my bad for assuming. never used a trans medal before, so never saw that option to dismantle it for a medal coupon to get another random one after stacking 3.

Potentially, you can get more NPCs medals just by exchanging 3 Caravan Joe ones...but I don't see myself doign that :s

Its exclusive to the item, not the event. What happens is that when you use a medal for a form you already have, you get a prompt that gives you a medal coupon (not the one from this event) and if you stack three of those you get a new completely random medal. Correct me if I'm wrong but that medal doesn't include ones listed Limited Time (Morrighan for example), event, and Saga.

You guys don't use the Saga medals?

No I do not. I told myself to hold off on NPCs and just continue to passively rank Trans mastery and getting previous collections...off-topic, someone in alexina let me borrow a dull weeding hoe.

Green Sacer-some-funny-name-that's-hard-to-pronounce? Either buy a dull weeding hoe or ask a friend who can get the passes to drop you in the dungeon.

What Infodude described was what I was wondering about.

I haven't done saga nearly enough to have repeats of the saga medals.

You don't have to have the medal in possession to make a coupon, just right click it. Also, stacking three doesn't automatically turn into a medal. You have to stack three medal coupons (which look like 1x1 broken medals) and right click-use (or ctrl click). It is true that saga and event medals are not included, but I am not sure about limited time like morrighan, as Infodude suggested.

Limited NPCs do not appear.

How can we prove this?

Started to compile a list on the medal coupon page.

We can prove what is in the medal list. We can never prove what isn't in the medal list.

From what I noticed, all the transformation medals outside of sagas have yet to come up on anything tagged "Limited NPC" in the diary. I've seen about a few hundred for when I was looking for other medals for certain NPCs.

We still have no way to prove this, so we are not allowed to say it without claiming it is not a proven fact.

Let's then say... While we don't have conclusive evidence, it would most likely be that you can not get limited medals from turning other medals.

Limited Time came from a gachapon/event, right?

Also, Caravan Joe also has the "Limited" tag in the diary, what are the possibilities of getting him?

My understanding is: the only way to get the limited coins was from the second gacha that was released.
