Requiring "Past" talismans is really messed up.
Hardly anyone has them.
All for the theme of "Past/Present/Future."
Atleast they could have been obtained as 3 of the arena challenge rewards, that would have made more sense.

In "ironite for souls" puchase events like this, I usually gamble 900 ironite once just to see if I can get lucky..... I wasn't.

When I logged in and saw there was a new event, I cringed. It's so exhausting.
There's barely any time to enjoy a sense of satisfaction from accomplishing the previous event.
Also, any feeling like your catching up on having most of the characters, lasts about a day.... cuz tomorrow there will be new ones. (But not really though, it's actually a pre-existing toon w/ a new look and passive.)

Good Luck Troopers!
