Before Leonel set out again, he paid keen attention to the changes in his abilities as the new owner of an Heir-Grade territory.
Many things were pretty standard. For example, there were upgraded outposts, and there were also some defensive measures unique to Heir-Grade territories.
Right now, the walls Leonel had access to were already quite fantastic. They were a hundred meters tall and over 10 meters thick. On top of that, they were forged of a powerful metal alloy. However, other than that, they were relatively simple.
Many of the options included infusing it with certain large scale Force Arts that could greatly strengthen it. There were also methods of banning flight within a certain range of the city, the more he paid, the larger the range would be.
What was more interesting to Leonel, though, were the unique upgrades he could gain since he had a special ocean territory. Many of these things, unsurprisingly, were related to ice.
