Castle myths

Mute + Castle is not a combo. The wiki names Castle (and Azami) as good Mute partners: the panels hide disruptors from sightlines and recon. It is a modest anchor/anti-intel synergy.

Key Castle facts (Y11S3)

Castle has 4 Armor Panels (up from 3 in 6.3.3, Oct 2021). They go in doorways or windows instead of wooden barricades, block bullets, take 9 melee hits and leave a drone gap at the bottom of doorways. (since Y6S3 (6.3.3))
Panels are destroyed by explosives, breach and hard-breach charges, Sledge's hammer, Ash's rounds, Zofia's impacts, Maverick's torch, Kali's Lance, Ace's SELMA, Flores's RCE and Ram's BU-GI, and by a flying operator hit by Nomad's Airjab. Fuze and Ying fire through them, and the BOSG.12.2 penetrates them in 3 shots.
From Operation Tenfold Pursuit (Y11S1, March 2026), Kaid's Electroclaws electrify Castle panels, so breach charges and Ash's rounds are burnt on them. (since Y11S1)
Mute works well with Castle (and Azami): the panels cut attacker sightlines and recon onto Mute's disruptors.
On window-heavy sites, panels on windows shut down window entries and rappel swings until they are blown.
