This mode supposed to work like Pilar Detector de Falhas
Places an electrical pylon on the ground that will resurrect all party or raid members within 5 yards after combat has ended.

You can get the schematic after "Cheating Death" Engineering quest ~ 26 quest in Legion engineering questchain. More info in the comment here: Engenheiro da Legião

Módulo de Demólitus: Modo de Distribuição de Petiscos Similar to Banquete Farto but gives 225 versatility https://www.youtube.com/watch?v=FP7Wy4FZMmI
6 Módulo de Demólitus: Modo de Conserto Same as Martelo Automático https://www.youtube.com/watch?v=WghKzvuKQyQ
7 Módulo de Demólitus: Modo de Exibição de Fogos de Artifício More info https://www.youtube.com/watch?v=M8KlFJrQhag
8 Módulo de Demólitus: Modo de Detecção de Falhas Same as Pilar Detector de Falhas https://www.youtube.com/watch?v=uvHn4Sl9LrA

How modes work:
Craft some module once
Install it by speaking with Demólitus
Now you can activate it every time you summon the Demólitus
Can activate only one mode per Bateria de Demólitus use
But Bateria de Demólitus has short CD
