Which hero to ascend for my unique tome?

I’ ll get my 6th tonic and 6th tabard this month and I have the doubt in which heroe spend my unique tome.
Lady Locke or 2nd Clarissa.
Green heroes I have in 4/80: Alby, Telly, Kingstone
Purple: Quintus, Clarissa, Víctor.

Other feasible projects: Domitia (3/70), 2nd Telly (1/1)

What do you think?

Wait til we know Telly nerfs

Yes…you are right…indeed I have one Margaret at 3/70 right now
