PoE Vaal Flameblast of Contraction, Channelling builds

hi guys, can somebody give me any ideas how to upgrade my build? goals are usual stuff more dmg more tankiness and more utility would be nice here is my pob: i added a second shield i crafted to play around with but dont rly know how to make it work... i crafted it to play with the adrenaline charm/petrified blood and then found out that the charm only works with life flask :( i also would like to keep supress cap and had some ideas with triple implicit boots but it looks very unrealistic looking at average locks it would cost
