Just remembered. I also got my hands on some element damage resistance talismans. Since the tribulation goes through all elements, the more the better. I think you can get them from doodling randomly when drawing on a blank talisman.
If those are all the relevant talismans you have then yes, they are significantly better then nothing. If you have other relevant talismans though the element resist ones are woefully sub-par for the yaoguai tribulation since it goes through all five elements compared to talismans that help your defense in general (or attack if you are using an artifact).
That said, they are very good for the single element tribulations.
I also happened to look at the "heavenly Pancea" skill, and it says it restores Qi..... Could I perhaps just spam this around the tribulation fighter???
No. Miracles from other people can't interfere with a tribulation. You could have the dude doing the tribulation learn a qi restoring skill and use it on himself though.
Try doing it without the artifact. It's powered by your qi and things I've read basically say that you're better off not using artifacts unless you have a REALLY good one, or you've unlocked the ability to use multiples.
Having multiple artifacts doesn't really help with tribulations much since it doesn't impact the fundamental issue.
The issue is that artifacts have no protection skill, while your dude does. So if your artifact is hit with a 1000 qi damage attack it takes 1000 damage then goes back to you and drains it all out (aka, 1000 damage taken). If you get hit by 1000 qi damage your protection skill can reduce it a bunch (eg. to 750 or 500 or even less then 100).
Eventually with high enough artifact power the fact that the artifact takes a bunch more damage and thus drains your qi way faster is less relevant then the fact that it deals like a million damage and kills the tribulation way faster.
Also note that the lower your artifact qi the better since any extra damage it takes just disappears (eg. if a artifact with 100 max qi is hit by a 10k damage attack it blocks the whole attack but is drained then goes to fill up 100 qi from you and the extra 9.9k damage doesn't matter).
