Meta gears?

[GM-Ayu]

There's also some new card options on top of the gear options mentioned by Kiyoshi here:

For the SUPER high end stuff, you can also consider Chen card (card info to be added 'soon' to wiki, eventually). It gives ATK in accessory based on your base max SP with a cap of 35, and is considered to be a contender for new thresholds for Champ even though it may shift your gears around again to see what Str parameter you can keep.

Wizards got plenty of new card options for what to do, depending if you're aiming for fast cast or high int instead. Babayaga card got +4 int but -2 dex as headgear, which allows you to reach some pretty absurd int threshold at a sacrifice of no Isilla effect and have dex penalty on top of it.

In footwear, the new snow harpy card is reverse of Chen in a way where you get max HP based on your SP, which for hwiz got a very high chance to be better than the usual 10% hp footwear cards of old.

Staff of piercing is decent if the enemy mdef is high (which is the case for Bifrost Tower). Staff of Destruction got raw power being a 25% matk 2h staff. Otherwise, magic bible shield has 2 int and can stun enemies if you get hit. For 1h weapon, you can also consider BG staff to strike a balance of having some int but also having cast delay reduction. Mental Stick at high refine will reduce cast delay pretty drastically. Finally, Lacrima Stick has a complete combo from bio3 + bio4 hwiz/prof to really boost your Storm Gust, but good luck getting that combo at good refine.
