Beating Frieza is challenging since none of the link skills or categories can nullify Frieza’s damage reduction.
For instance, Awakening Medals: Golden Frieza (Angel) are needed together with the Ultra Instinct Goku event ones to get LR Miraculous Outcome Goku & Frieza (Final Form) (Angel). So, LR hunters out there listen to me.
Beating Frieza is all about damage and getting type advantage against him. In phases 3 and 4 Frieza’s type will be INT. If you manage to surpass phase 2 (STR type) unharmed, a Super PHY team will guarantee your success. For example, take a look at the video down below.
Other category teams are quite viable aswell. However, you should avoid teams that heavily rely on TEQ characters. If you are a F2P player, please notice that Ginyu force’s category team is barely viable for this challenge. LR Ginyu Force Reborn Ginyu (Goku) and Brutal Bind Guldo both suffer from type disadvantage and your only type resistance in the last phases is Lethal Charge Recoome. So it is not the optimal choice, but if you are left with no other choice, well, you could give this team a try.
As for all the other dokkan challenges, be ready to make a wise use of your items (and more importantly unlock all the available item slots). Avoiding Frieza’s Super Attacks or countering them (e.g., delaying them, increasing your defence) is crucial to your success. Don’t underestimate items, simply DON’T!
