Official pre-launch material has confirmed that combat customization is a major part of Phantom Blade Zero. The August State of Play focused on weapons, difficulty options, side quests and how players can shape their combat setup.
What we will not do before release
We will not publish a “best weapon,” “best build,” boss strategy or damage ranking before those claims can be tested against the release build.
What comes next
After release, this section can expand into weapon pages, combat mechanics, boss strategies, builds and upgrade-system guides with direct internal links from this page.
