waking dream / lucid dreaming

the duration of purple flames of chayula feels way to short to actually be useful.

The only way to get a decent stack is by standing in a small cubby surrounded by walls with one exit and afking to wait for flames to spawn in the only path out, but the duration is just too short to even utilize this anyway.

it also doesnt increase the duration of purple flames of chayula gained from Mantra of destruction, probably doesnt even increase the damage since duration doesn't scale either?
