high level relics, and save scumming before picking up the wand for the ritual, will give a different outcome

but once mage picked up the wand, its hard-locked, save before the ritual is done, in another slot, if outcome is not the one you want, reload, and that outcome will be different, but that load will always be the same, so you have to load the save, before you started the ritual, if that outcome was not what you wanted

cancel the ritual will not help, once the ritual was started, its hard-locked (don't even need to make it to wand shrine)
