I see, I'll try again after deleting and reinstalling the mod. Thanks for the reply.

Hello Antony I haven't played in months but I tried to play now to test what you said but it appears in version 1.177 all five evil god seeds such as Life, shadow metal, fire seed , water seed ,and primordial seed do not cause the instant death, It maybe possible that the seed was a dragon vitality pill ? because pills that give Qi will to cause instant. The dragon vitality pills are for quick bulk regen on Qi and will cause instant death. all five attribute pill seeds can be taken any time at any level except for physical cultivators you must take the pill seeds ( the five that add attributes) before promoting a disciple into a physical cultivator or the seeds wont have any effect.
I hope this helps answer your questions, as far as I know I don't think the recent updates have change my mod though. Have a good day.

I know you haven't played in a while, are the Seeds supposed to be eaten by people before they start being Cultivators or once they reach basically the peak? I fed one to each level and it seems below Golden Core is instant death for everyone, type of seed didn't seem to matter...

Hello thanks for trying my mod and enjoying it, I have not played in a while been busy lately, You can always use a Shendao cultivator to clear mood afflictions for this or stack lower tier recovery pills. Have a nice day.

Really Nice Mod but the high end dragon vitality Qi recovery items being T12 means they quickly cause the greedy mood affliction in golden core + Cultivators, Is it possible to change them to T10 or something
