Undead Artifact Set unlock

[Svamp]

I'm using Lara Crypt, and on a fresh Undead run when I've exported ~4 seconds after abdicating, it's giving me an estimate of nearly 60 000 excavations to find Dusty Coffin.

I also checked right after reincarnating, thinking time in reincarnation might be included, but it didn't make much of a difference.

Anyone able to give me some tips?

Is there any different artifact, you still got a chance for? Doesn't sound like your chances to get this one are very good at the moment. Otherwise you could keep digging for a while at undead runs, just to get the counter down.

No, I've gotten all the others I'm eligible for at the moment, only missing Dusty Coffin.
The formula only looks to be affected by the amount of seconds I've spent in a game, so it's not likely going to get better, is it?

Chance of getting dusty coffin goes from a minimum of 1/3000 to 1 in about 50000 (small value of roughly 0.00002) after 60 seconds. I'm not sure how many "a few seconds" are, but the formula is (1 / (30 + x ^ 1.5))%, where x is seconds in game.

Go forth armed with the knowledge, and expect to burn a few Rs trying to get this.

On Lara Crypt, go check "Small Values", it's right next to "Artifact Forecast".
The value (in seconds) is the time you have to dig Dusty Coffin since the start of a new abdication.
My advice, check for a good small value, dig almost up to this value, abdicate, hurry up to dig. If by any case, you miss the timing, don't dig, once a small value is used, it is gone forever.
Hope my gibberish was clear enaugh.
