The Parazon is a neat addition, but the 5% health threshold is a little low, and the 3 mod capacity makes mods not really worth it. The focus system does need some expansion, so why not introduce a similar upgrade path for the Hidden Blade? It should be upgradeable through killing Liches, that way they would be more worth it, and won't be dead after getting whatever weapon a player wants. They should have three paths, tied to each faction and their Lich equivalents. Hopefully the Parazon isn't forgotten about like so many other things, it could really open the game to some much needed variety. TL;DR: Parazon seems too gimmicky, they need better upgrade options, giving them a tree to upgrade them for different playstyles.
