pure DB is really difficult to finish alone. Many have tried it over the years and failed. Now with fafnir scale, DB dmg is the highest it's ever been, so i can get that people will try to use deluge to get pass her (I rmb seeing zayaan's video last year, with his godlike gears getting pass valk with DB RK and it only did like 35K dmg, so it still takes a long time).
However, as you guys already discussed extensively, valk is quick to spam gambatein so if you are soloing, it's going to get removed pretty quickly. Not to mention once you spend like what, 5-10mins wasting a lot of time recasting deluge and gettting a few wDB off, she reaches 1M HP and boom, here comes Power Up, Agi Up, Earthquake. You're 100% going to die that one time at least when it happens, unless you're a GTB user (but i read here no MVP). Then you revive to her triple damage and double aspd hits, which are very hard to survive without spamming lots of pots and yggs unless you go like some 70%+ reduc build (which severely limits your DB dmg).
In any case, if you somehow manage to kill her that way, good for you, but it will be so bad an experience i don't think you want to do it every week. Like being a masochist looking for somewhere to burn a lot of consumables and time- all for something that someone else takes a couple of seconds to get over.
If you insist on clearing with a pure DB RK, consider getting a tank duo. At least with the tank taking valk's attention, your deluge doesnt get cancelled so you can just braindead spam wDB until she's dead.
