I must also add that, currently, off-hand weapons are not working, so a bronze offhand would technically work RIGHT NOW. Link here: https://www.youtube.com/watch?v=QiG_DkLKtHk For all things being equal, and the game working properly, using an offhand chaotic will work perfectly fine. In all honesty, you probably wont notice a large difference between using chaotics and t-90 at the slayer level. This comes down to what you want to do with your money I suppose. If you plan on bossing, the T-90 would be essential, so take that into consideration if it concerns you. Other advice here I see looks great and good luck getting 99 defense!
