The primary function of Belphegor is her -30% Rage Gauge, which is absolutely insane. This can - in some content - entirely let you skip Rage phases where not even an a full SSR party would let you do it. Particularly if you don't have access to PF yet, something like Belphegor + Full Burst just might let you clear AQ5. Since you have debuffs fairly well under control, you can also combine this with Gilgamesh's -20% Rage Gauge for -44% Gauge for even lower damage requirements... ... though, not entirely sure how well you'd fare in the previous rounds if this was a requirement for you.

The primary function of Triton is her Combo-, which usually prevents all enemies from entirely doing Double and Triple attacks. This makes your runs far more secure, since a "oh fuck important character X just got triple punched TWICE this same round and died from full HP!" simply cannot happen anymore. This held true for AQ4, but I've noticed that AQ5 last boss has a small chance of doing Triple attacks still under the debuff.

Whether or not you need either of these things is questionable due to having increased damage output from Rudra. You can focus on other teams as well if you want to.
