Best training chapters to get event items

Does anyone know. What training chapters so I farm in order to get event items like lifedrops and soulstones?

Do the chances of them dropping increase in the higher chapters? Or are they all RNG?

The reason I would like to know is because if the chance is the same throughout all chapters, then I should just stay on 1-1 since it costs the least more of training points!

Oh hey! Thanks for the link.

I notice he hasn't ran any trials for the higher training chapter though. Do you think it scales?

Meaning, would 37 give more items?

From my experience, I did gain more Soulstones in the higher training missions that costed me more than 30tp each step, so overall the results are pretty much the same.

Vials and other BT/stat boosting arena items will give the same results as well.

I think the only time a certain training mission can work to your favour would be when you're farming for feeders or searching for monsters during training events (1-1 being the most popular choice).
