Can't equip certain equips

I'm a lvl 82 DB and I'm still using a lvl 30 dagger that I bought from kerning and a lvl 20 katara that I also bought from kerning. I have several lvl 80 equips that have either dropped or I've bought but I can't equip any of them. I have the required dex and luk but when I double click or drag to equips, nothing happens. I've tried taking off my old equips and equiping the new ones, doesn't work. I can re-equip my lvl 20-30 stuff with no problem. I can also equip armor that was dropped.

Thats a bit weird Igneus, I guess thats one of the DB Bugs, Wait before someone else answers i havent heard about bug like this.

The passive skills that add Dex and Str is bugged. That is why you can't equip, I guess.

Either the Physical Training skill is glitched, or your katara/dagger gives you DEX/LUK so when you take it off that DEX/LUK is gone which stops you from equipping your next ones. Just try to add more DEX/LUK until you have enough. There's a free stat reset NPC in @myple so you can use that.
