How Best?

Leonel tossed the net of runes in his hands and then chose a direction. He needed to test this thing first. He wasn't a fan of jumping into things without information. 

Soon, he found a Tier Five to target as it would take heading to a new mountain range to find another Tier Six, and he had already run out of lower tier mountains to take advantage of. The next few were all guarded by Tier Sevens at the peak at worst.

It was more awkward than he expected, but he finally got the hang of it. Plus, it was also much faster. It only took about 20 or so seconds now to get it to work, whereas before it had taken over a minute. 

On top of that, he had dialed in the power. 

Essentially, it could explode forward one time with a strength just a one and a half Tiers above the creature trapped within it. If the target was in a vulnerable position and exactly one Tier above the creature within, then it was almost certainly a sure-fire kill every time.
