This new spell was important to his plans going forward, disgustingly so. To show that, Darius immediately began burning his mana turning as much sand around him into humus, or dark earth.
One moment it had been porous and heat trapped sand only to turn into semi-porous and nutrient-rich soil that could be used to grow crops. Darius made sure the area around which he had built his settlement was turned to humus first.
This took him the whole day and even with his huge manapool, a few rests to recover due to wastage.
Darius did not have access to his system Inventory for obvious reasons, so he could not pull out one of the many potions he had created and tossed into a slot oh so long ago.
This was fine for him, as he regarded this as his chance to learn how to conserve mana. The larger his pool, the more he wasted, but conversely, the more he could practice with.
