Funeral.
A bright bolt of lightning fell on a tree, the tree was burned from the top but soon turned back into its original form.
Kamiya clicked his tongue, he lifted his wand once again and cast another spell at an incoming vine, "air blast!" The air's pressure sent the vine away, it snapped into two but regained its lost part quickly.
Kamiya started running away from the plants and trees, he continued to cast high-impact on contact spells such as blast, explosion, fire element, air blast, etc.
He inflicted good damage on the plants and trees but all of his efforts were marked wasted when they grew back into how they previously were.
"Lightning crash!" a thin bolt of lightning came out from Kamiya's wand, he directed his wand down and the lightning bolt fell on a tree.
Seeing that the tree had regenerated, Kamiya retreated for now. Since he had dealt a lot of damage to the house guardian, the increase in his threat level increased the house guardian's radius.
