I need some help on how to learn and load mythic spells. The two relevant sources are:
Mythic Spell Lore Benefit: You can learn a number of mythic spells equal to your tier and can expend mythic power when casting them to enhance the results.
Casting Mythic Spells: If you know the mythic version of a spell, any time you cast the spell, you may expend one use of mythic power to convert the spell into its mythic version as you cast it.
That says that on a Wizard 7/Mythic Tier 2. So I know two mythic spells (Dimension Door, Haste) and I have learned three Level 4 Spells (Acid Pit, Ghost Wolf, Solid Fog).
My question is now: To cast Dimension Door (Mythic) do I have to learn Dimension Door first, so I can enhance the result? In the case above I would not be able to cast Dimension Door or do I get the spell Dimension Door in addition to the three Level 4 spells.
