First things first. Which character are you attempting it with? Also, do you not have Kanai’s Cube? If not, get it, learn how to use it - total game changer.
And yes, get faster. However, don’t just skip over all the trash mobs. Every little bit helps and it also helps to get pylons to spawn. So kill some of them as you go. If a mob type is taking too long, skip it and carry on. Skip mobs with ‘Juggernaut’ affix - take too long at your level.
Take that amethyst out of your Wizard’s wand. Use Emeralds for the +crit damage bonus.
Make sure your gear bonuses match your selected skills, also. If necessary visit the Mystic and reroll them. For instance on your Wizard boots you have ‘Increases Arcane Orb damage by 11%’ - Arcane Orb isn’t one of your selected skills. Change skills or change that stat, your pick. Just little tweaks like that can make all the difference. Visit maxroll . gg for more info and build suggestions.
If needed, send me a friends request and I can help you in game. Easier than advising in a forum board (I finished season on all three servers so have time to lend a hand if you want).
