LR Goku is also going to be your primary source of damage, so bringing two LR Gokus helps to not only dish out more damage, but you have double the chance of utilizing his super attack(s).
The final level of Summit of the Universe, where you obtain the Dokkan Awakening Medal required to turn your farmable Frieza into LR Frieza, is three rounds.
Frieza only has one health bar on this stage, so this should be quite easy to defeat.
Expect a grind, however, when it comes to farming The primary restriction, while it seems difficult, is that you can only bring freely obtainable characters to enter any level involved in fighting or obtaining LR Frieza.
During the third round, with my preferred team composition, my AGL units take 10k tops damage per normal ATK from LR Frieza.
From my experience, LR Frieza will launch a super attack every other turn.
With three attacks per turn, and a super attack every other turn, expect to be able to tank without healing for two turns.
Prime Battle is the event in which you will take on, farm, defeat, and Dokkan Awaken LR Frieza from start to finish.
Once you select the event, the first level that you need to farm is “Defying the Emperor”.
