Борис Федюкин Злые языки говорят, что так дела обстоят в немецкой НРИ Das Schwarze Auge. Не проверял. Вики говорит следующее

Elves, druids, shamans, witches and mages can cast spells and have astral energy points; the starting value of astral energy points depends on the attribute values the hero has when created. The system is based on the memory of the player; the player must speak the formula without reading it during the game. When the formula is correct the spell is cast, and the character loses astral energy points corresponding to the spell.
