Radiver sells the Slayer Cape of Accomplishment to any player who has achieved level 99 Slayer for 99,000 coins. Previously, Tatiana sold the cape. Additionally, for players who have a level of 120 in Slayer, he sells the Slayer master cape for 120,000.
- A popular theory among players was that Radiver is an elf. He confirmed that he is a human.
- He and Kuradal seem to be lovers, since he sometimes mentions her in a romantic way. If you talk to Kuradal about him, she will show hate instead of love. This probably indicates a future quest which will involve these two.
- He also appears to be great friends with Duradel, the father of Kuradal, as Duradel taught under Radiver. After While Guthix Sleeps, Radiver said he will have sworn vengeance for him. Lapalok appears to not like Radiver that much since he doesn't know too much about him.
- Strangely enough, he is usually not smiling, but when you talk to him about Tasks, he will actually smile.
- He shares the same exact model of Ali the Wise, possibly indicating that he is indeed Ali the Wise. It was confirmed by him that he and Ali the Wise are brothers. When the Ritual of Mahjarrat was released, he was corrected, and instead said they were sworn brothers. Jagex confirmed the "Brothers" part wasn't supposed to mean actual biological brothers.
