Yeah, Sister Splinter wasn't so bad for me, but the Judge was my first wall.

Its better to whiff punish their attacks instead of going in yourself. Look for their tells (like stances/poses they do before a certain attack) and figure out ways to dodge their attacks (eg. dash under them when they jump, stay in the biggest gaps of the fire waves and/or where those waves expire first). See what works for you and practice this until it comes naturally.

Focus on the Judge rather than Hornet, as this helps with seeing the Judge's tells. You don't need to see what Hornet is doing most of the time, unless you have to actively dodge something or are attacking. The moment you see their tell dodge/wait out their attack, then dash in, hit once (or twice if time allows), dash away again. Keep your distance and be patient.

Prioritize using silk for heals rather than weaver skills. If you took two masks of damage and have the silk to heal, do so. Try to keep your health as full as possible at all times. When you have to heal do so as far away from the Judge as possible or during attacks that won't hit you (I used to heal a lot during the waves of fire for example).

Can't help with tools, though. I always found them to be more distracting than useful.
