Sundered Doctrine Mechanics
symbol heavy mechanic, at the start follow the waterfalls to arrive at the first encounter.
First Encounter you have a a medallion with 2/7 symbols on the wall, and 5 rooms each with a medallion. You need to kill the bat enemy (truth seeker) which spawns in one of the subjugator rooms, the symbol it drops is the panel you need to hit with light, in the main room whichever symbol is missing signals which crystal you need to use to light up that panel.
For example: Guardian is the truthkeeper symbol, Guardian is in the top left room, the missing symbol on the main room panel is on the right, you need to use the right side crystal on the top left wall .- u/Individual_Winter690
You do one ray into one room, then 2 rays into 2 rooms, then using 3 rays into 3 rooms, one lens per room.
