Think about tier 2+ Richter as a blood Mage weilding a sentient, chaotic, bloodstone that is on his side and doesn't waste energy by sending its power away to some old god... 1. Instant one man army (just ask the goblins) 2. Enemy armies are now just food for him to unlock max level enchantments (lvl 7 sonic damage here we come!). 2.5. Same for the beasts in his lands 3. Alma would have access to this basically unlimited mana as well. 4. Possibly access to further blood spells that the stone knew? He could still probably win these as prizes in the dungeon so maybe not an exclusive of keeping the stone.
