Would help to know which part youre struggling with and may help to know that she is incredibly buggy this season. Aldkin's firewall cancels many/most of her mechanics as they're considered missiles including winds of hatred in p1. At the start of the season her grey missiles were also 1 shotting through immunities (like, blood mist). If you have the damage, consider running Belial's boss power as main if your build permits it (death trap shouldnt need this), and run shroud/shako with ga max life. This should make the damage intake manageable even if you miss some mechanics but it wont cover up mistakes on all. If you have enough dps/rng, she won't do her final move in p1, but if you lack it, or get bad rng, she'll crash down on the platform dealing heavy damage in the last portion of P1 and perform a non-traditional move, such as the triangle formation winds of hate. Her traditional version of winds of hate seems to involve her landing softly for no damage with winds, the outside of which can flow in the same or opposite direction of the inside, with the inside always having a 2nd missile that follows the 1st. It also helps to know she sometimes/often lingers on the edge of the circle in p1, and can be damaged while there. Doing so progresses the phase faster.
In P2-P4 if you're missing the DPS check, she does stuff randomly, but if you meet the DPS check, she typically destroys the north section first, the right section 2nd, and the left section 3rd. If you cant avoid or escape the pull/suck in, you'll want to CD there before it completes., which can include Belial's eyes of protection power. If you dont meet the dps check on her, she'll do things you don't expect, such as leave the north and fly south, or fly left and combo the room while not destroying a portion of the platform. This means with low dps, she can fly to a corner of the room more than 3 times and only ever does this while breaking off a piece of the platform at specific thresholds. The easiest build to complete this with this season is probably hands down death trap rogue with a ga on reduction for chest/legs. You dont need a banish lords either to make the build work sufficiently although this may drag out the fight on t4.
Hope this helps.
