Hai! I recently leveled my forge to 45. I noticed that it stopped getting better a while ago. Unfortunately I didn't record its progression but does anyone know when it upgrades again? Should I keep leveling it? Its crazy expensive now lol

I'd say you're good with 32, it gives you a safe and some pretty good chances for top level artifact production.

Hrm, what are the artifact production %s for 45 and 32? I only have 1 - 12 recorded so far. ^^;

45 is
Artifact production:
I level - 30%
II level - 42%
III level - 21%
IV level - 7%

It was definitely expensive lol...

Chances crafting art with 32:

1 - 34%
2 - 40%
3 - 20%
4 - 6%

For 7% for 4 level arts you will need a 40th lvl forge.

an update;
Again I failed to keep any real record but currently at level 50 the stats are

Artifact production:
I level - 29%
II level - 43%
III level - 21%
IV level - 7%
