With Ardyn you can:
- Fight (Royal Arms, Spectral charge Dark Tornado, Cerberus 0, Shadowstep, Phantom fade, Counterosmosis, Phantasmal leap, Royal retribution, RIsing Phantom)
Camp
- Teleport to very high places usually not accessible (keep pressing summon button to activate it)
Shop
- Take quests (not all, be careful. Use party with Noct inside to reduce issues)
-Talk to Cidney (I see you)
- Fight again.
- Change Ardyn's hat (ATTIRE) in equipment menu: CAREFUL though, equipment menu might freeze. Do not scroll down to attire, scroll UP to go access attire menu. You can change attire and close menu.

You can't:
- Do main story quests (unless you change party using archive menus)
- Daemonize to gain phantom gear level (overdrive mode will help you cover that part)
- Drive Regalia as Ardyn
- Ride chocobos.
- Initiate battle with weak/non aggressive monster. It takes more time and sometimes require Noct to actually attack them to start battle
- Ever go back to normal gameplay once you started playing Adagium. I warned you, again.

Known issues:
- Music might not trigger as it should. Sometimes in town you will get field music.
- Ardyn menu look partially like Noct's (a few more fixes are hopefully on the way)
- Equipment menu will be a mix of Ardyn and Noctis. You can equip standard swords to Ardyn to increase your stats, and change visuals too.
- In equipment menu, do not scroll down from weapon to costumes. It will freeze the game.
- Some battle sounds/voices are missing: Ardyn won't be as talkative as he usually is. I'm working on it.
- Ifrit does not load/come with you everywhere. He will mostly pop up, unleash his skill, and sometime stick around untilthe fight ends.
- Can't use daemonify. Yet. Episode Ardyn enemies will be integrated in a later update for you to enjoy daemonification.
