Tanto of Slashing for Debra or legendary and whatever left for 20 tokens?

Emergency question as there is only 1:45 left, I got exactly 80 tokens. Now I wanted to go for the tanto of slashing but I am using corrosion daggers at the moment? So should I go for 1 extra legendary or for the tanto?

Thanks y’all! Much love! ~

Ended up with the legendary boner ~ I got Debra, my Deb is now Lvl 6 discipline :D
