Seeing Red - A Complete Red Mage Guide

[Mordred]

If you have both verstone and verfire ready at the same time, you should be using the same spell twice in a row. As an example (under both verstone and verfire ready): hard cast verstone, then DC verstone immediately after. If you were to hard cast verstone and then use verfire to stay balanced, you might "overwrite" your existing verfire ready or just fall back into an impact/jolt 2. You can then chain them all the way up to 80/80 without having to cast an impact or jolt 2 (assuming your mana is close enough to stay balanced after two white casts or two black casts in a row).

I really don't get this. Don't you need Verstone ready to use Verstone? How do you even DC Verstone back to back??
Also DC Verfire after Verstone is bad already as you better of DC Veraero or Verthunder which has higher damage and increase more mana.
