Need help upgrading my Frost Blades slayer, 240 div budget

I followed Fuzzy Ducky's frost blades slayer build guide at leaguestart and by farming alva temples and essences with it ive gotten more currency than ive had in any other build, ive managed to farm around 240 divines and now i want to upgrade my build to do as much hard content as possible, think is im a chronic guide follower and whenever i tried planning my own build they barely managed to do red maps.
Biggest issue right now is that im kind of squishy, probably due to chaos res and the most obvious upgrades i can think of are a mageblood to fix resistances and get more armour, i can even drop the diamond flask and still have 100% crit chance according to PoB to put a different utility flask up, other upgrade i cant think of is dropping some spell suppression passives since im already at 100% and my bandit choice in case i end up going for mageblood in order to get some passives for cluster jewels, but again i dont know which ones would be good.
