Drop the sup gollux belt and opt for double sup pendants (keeping 4 set gollux). This gives you more freedom to keep the CRA 4 set and go with Abso belt, cape, glove, boots, shoulders. Or even keep the tyrants and go for a 3 set abso, which nets you 30 all stat and 25 more atk over 2 set.
Edit: 30 day 2nd pendant slot is in Maple rewards shop for 3200 points, which can be done within a week if you go for 10 daily bosses a day.
I don't think an Absolab belt exists and but I've decided to sell my tyrants for 3 Set Cra and 5 Set Absolab.
Trying to go to Auction house gives me the message "You cannot access the Auction House at this time. Please try again later."
I've tried restarting Maple and it's the same.
I'm in Bera if that has to do with anything.
Edit: It just got fixed and is working properly again.
