I don't use the fast leveling and also playing on tq legacy so I didn't check every script for offset with the tq_dx11. version. But you can edit the script for fast leveling and change the 15cc to 156c and hit ok, then save.
And the loot script does give legendary on epic play mode, just finish on normal and playing on epic now and got 2 purple legendary from 2 chest. Unfortunately according to https://www.tq-db.net/en the legendary items are not that many and are high level. Doesn't look like there are randomly generated legendary items.
Tested the dx11 create artifact with just formula. Had no issue with crashing. enable script at the artifact crafter. the create artifact became ungreyed out. click the create artifact. took the artifact. disable the script when not needed.
