ok then I also have a few questions about the Dark magician you mentioned that The powers of Dark Magicians are far reaching and encompass many powers associated with other Magicians, and Because it is only the act of summoning a spirit, Dark Magicians actually don’t use much of the Great Power themselves. I that is because assume they can summon things like elemental sprites or one that can heal and that's how there powers overlap with those of the other magicians?. I was also wondering if they can do anything else like for example casting simple binding or blinding spells or even shadow spells?. One last question I was thinking because they have a change of becoming of possessed by the spirits they summon would it be possible for them to summon dead ancestors, relatives and or friends that would be willing to help them out and not try to posses them?. I ask knowing if they only summoned those types of spirits they would not likely be able to summon any really powerful ones as it would be unlikely that they would no a lot of dead people that where that powerful maybe one or two if that. If this where possible however this would allow them to summon multiple weaker spirits to do the job of a powerful one as well as allow them to focus completely on the battle as they would not need to focus on forcing the spirits to do her bidding as they would be helping them of their own free will.
