It is just me, going to appoint Lancelot soon. So far, it is his soul splinter that is hardbto obtain from the altar. I'd say one splinter from 7 to 8 attacks? It was more frequent with Camilla's splinter. I got 4 of his splinters from the Asgard continent alone. So don't forget to collect wondrous essences.
Anyway, I'd be looking at that attractive scar closer.
