So... Almost level 50. What to do?

[Thaliss]

Hi,

Advance in the story is a good thing

Then you will unlock the lvl 50 dungeons, and start working on your relic (zenith weapon)

Try some dungeons wanderer's palace (WP) and Amdapor Keep (AK) once confident move on more difficult content.
Your relic (chimera, hydra, ifrit, garuda, titan Hard Modes (HM) )

You can farm primals HM or king mog for weapons

You can also unlock Crystal Tower if you have friends or good FC you can be carried to equip with iLvL80

You will get tomes doing that that will allow you to buy equipment

Run Ultima HM, go for harder dungeons (Copper bell HM, Haukke HM, Pharos Sirius)

Get your Relic.. ( )

Run even harder dungeons - expert- ( Halatali HM, Brayflox HM, Lost city of Amdapor)

Start doing Binding Coil of Bahamut.

Equip yourself. Get your Relic

Start doing Extreme mode Primals.

about Tiers of equipment. I find better to talk about iLvl as it is what they show us and you have :

iLvL
50 (what you usually start with)
55 , 60, 65 (first dungeon drops)
70(expert dungeons)
80 (Crystal tower)
90 (bought or dropped in Coil 1)
95 (dropped in coil 1 or Leviathan Extreme or bought with tokens from Ifrit/Garuda and Titan Extreme)
100 (bought or dropped or upgraded Zenith to atma/Animus)
110(upgraded with a drop)
115 (dropped in coil 2)

Once you are there I guess you don't need anymore advice.

But most of all, enjoy
