Zone 0 Forest for all wild rollsIf I get to choose which Natrelmon I fight, I would like it to be an Omu, also I'm a Tracker. Does that give me some sort of advantage? It says I get +10/+15 but 10 what? exp?

It is an increased capture chance.

I'll note Omu as a declared Natrelmon, since you will likely have Rank II-III tracker.
