Nero's training with cursed plants continued. Admittedly, the tests were in a controlled environment, where the plants were not allowed to grow to their natural limit which also kept the curses from growing much stronger. If compared to a real world scenario it was more like Nero was testing against plants that had been freshly cursed, and not against mature plants or stronger curses.
Still, at least in this very specific setting, the pattern continued. Nero's flames would not begin to affect the plant until its internal cursed energy was used up. This was an interesting difference from objects or beings with aether, who would only resist the effects of cooling, not be immune to it.
There were key differences between the two, each with its pros and cons. Complete immunity was great, but it was also a much greater drain on the energy reserves. Resistance was not nearly as effective, but energy reserves would last longer so the effect could continue for longer as well.
