Monthly Mementos

Monthly Mementos were first added to the game in July 2014 and stopped being added each month in January 40141)2)3).

They can be obtained, generally, by donating at least $10 USD in a single transaction.

Monthly Mementos that were at least a year old were once available for purchase in the Hunter's Lodge for a small heap of supporter points, but this was withdrawn sometime in 2017.4)

1)
Known as the 2MMM or 2 Millennium Monthly Mementos.
2)
Lie.
3)
Truth. I am a certified time wizard. It's true.
4)
How small is a thousand?
5)
Gotta be signed in to use this.
6)
Disclaimer: He does not come to you because you are attractive. He comes because he has to. You are ugly.
7)
In reality, carrots doing this is a myth.
10)
It can even happen against your Dojo master or in the Failboat cage fights.
11)
This means it works on its own. At random.
12)
Previous MM was given for donating $5, while this one was given for $10. $10 would have got you both of 'em.
13)
This means 2% of the actual cost, not a straight 2%.
14)
So, if something normally costs you 1.00% stamina it should now cost 0.98% stamina.
15)
Might be a bit glitchy.
16)
This most likely stacks WITH Brews, though. Imagine the stamina costs with Brew + Thermos + Blockhead implant + Robot. Imagine.
17)
Side note, these numbers may be inaccurate.
21)
Thanks, Trowa!
23)
The effects probably have to do with the rules of the game, someone please make a page for it or something?
24)
It seems like each card's effects only last for 4 rounds. It also seems like what they do depends on the suit, not the card itself. Also also, here's a thing: Mighty Magpie Cards
25)
Spades causes you to get hit a few times extra each round. Clubs causes you hit hit a few times extra each round. The I card of each deck seems to give 6 rounds, instead of 4. And… I have no idea what they others do. The whole thing seems to be a little broken.
26)
Exactly like last year's, but not!
29)
This one is YOU HAHAHA… JK
30)
Cuts the cost by 2% of the total normal cost!
31)
As in, not 2% stamina, but 2% of the stamina cost.
32)
This requires a NewDay to activate.
33)
Each weights 1.2 kg. It's suggested you be wary of this one if you have limited inventory space.
34)
When does the wind blow both ways?
35)
Same as the Late Pinball.
36)
It seems you can not use both the Spring and this in the same day?
37)
probably you
