The skill tree does not include basic skills unless they are required to progress. Each skill requires every skill touching its box on the left. Hence, Arcane Omniscience requires Cold Steel, Wall of Fog, Graduate and Erratic Mana. In turn, Mark of the Wizard contributes to Cold Steel, Wall of Fog, Fiery Wrath and Teleport Assault.

Mark of the Wizard (marked *) appears twice in the Complete Skill Tree.
