89 Cast versus Casted

"I suspect it is because you managed to resize all the nodes. You did, right?" Dave answered Eldrian's question, bringing him back from his thoughts.

"I did? Yes, I did manage to grow them all to their correct size. But how does that change anything?" Eldrian could not understand why this was a successful cast while all those before had been failures. They had also used his mana and he had even felt the effect of the spell from time to time.  How was this time different? He questioned himself, finding no answer.

"It changes things, in that, instead of just releasing mana, the spell was now cast through mana instead."

Seeing that Eldrian still did not understand, Dave continued, "You see, before the magical crystal always pulled your mana out of you. In this way you lost mana even when the spell was not cast. You are probably confused since the effect of the spell appeared a few times."
