I last played around when Kamasylvia or Drieghan came out(forgot which was newer). Quit because of the Shai censorship but decided to come back when they partially reverted it. Needless to say, I'm a bit lost.

I have:

-Level 61 Wizard and Ranger

- TET Boss armor/TET heve

- TET Kzarka

- Tet Kutum

- TET Dande

- TET/TRI Narc, TET crescent/TRI capitotia, capotia belt, TRI Ogre

What should I even be doing at this point? I'm a bit lost as to what I should try to achieve. I have enough silver to buy a PEN dande or PEN kzarka, is it still worth it? 

Also, what should I be doing? apparently there's a whole new parallel game world? And ocean content? And instanced PVE? I'm pretty overwhelmed. Any suggestions?

Also, is there anything fun to do besides running around grinding mobs? I remember back in the day there used to be a battle royale mode that was a fun way to earn rewards, but they axed that to make it a standalone game :/ and there used to be some sort of a wave defense/tower defense mode, but I think that died too.

Supposedly there's instances now? Are they decent rewards?

Do season server, u get lot of free stuff from there.

Never saw the history one before, I need to look at that too.

1)  Start a Season character, level it to 61, timepiece another character and gradutate.  This will get you 2 level 61's charcaters for additional Family Fame and the ability to get a PEN Captia Necklace (IV Ogre).  You can then choose to try tapping your III Ogre or selling it for quick cash.  When next Season starts, do this again and get a PEN Capotia Belt (IV Basi), then a PEN Captotia Ring (IV Crescent), and other free IV yellow accessory equivalents.  You also get loads of Advice of Valks for upgrding Tuvala to PEN through Fughar's quests and loads of other freebies for completing the Season challenges.  Season is OP for new / returning players.

2)  Work on the guaranteed PEN Crescent Ring thorugh Jetina quests.  This is a 100% guaranteed PEN yellow Ring / Earring (ring is the best bang for your buck) for a fraction of the cost for the item on CM.

3)  While doing these things, complete the Magnus quests.  This opens global storage access, gives your characters a new skill, and gets you a free PEN Boss gear.  I'd recommend either a PEN Griffon's Helmet or PEN Red Nose Armor so you can start working on converting them to Red Grade.  Or, you can get a PEN Bheg's for more accuracy + DP.  Kind of a toss up, but IMO, you're better off getting a PEN Red Nose, making it C10, and buying a Flame off CM (or grinding for a Flame, up to you) as this will probably be the fastest GS gain for you (NA has Flames for Fallen God sitting on CM).  I'd suggest looking up a guide on how to start the questline, and if you're wanting to speed run it, BD Foundry has a quest-by-quest guide on completing it.  Really handy, if you need it.

4)  Finish any remaining Adventure Logs you haven't completed yet.

Instanced PvE is Marni's Realm.  You get 1 hour 5 minute access per day.  I forgot if there's a questline to unlock it, though, try looking up a guide :)

After this, you could consider just running with PEN Tuvala gear.  PEN Tuvala is equivalent to TET boss gear.  You could sell or try enhancing your current gear for cash or a chance at hitting an item or building up a high stack.  Or keep it, it's up to you.  But it's an option since your next goals would be getting full PEN weapons and armor.  Jetina has guaranteed PEN weapon and armor quests now too.  Recommend looking up a guide and calculating the cost of the 100% Jetina system versus the CM prices of the items.  It's probably most cost effective to make 1 weapon and 2 armors with the 100% system, but I'm not sure.  You'd have to do the maths and figure it out.
