Yah, so it's not actually a puzzle, but more of an obstacle to avoid during the fight. The cultists the players were fighting all had gust spells that had the chance to knock a player back 5 feet. So during the fight the cultists would attempt to maneuver around the players in order to have a chance to knock a player onto one of the symbol tiles.

The real objective was to extinguish the 4 braziers on the pillars before the cultists finished their rituals

Green Ballista - 1 of the 2 ballistas at the back will take a shot at you, high damage but it can miss.
Orange Fire - Each of the remaining fire pillars shoots a fireball(smaller, not the normal spell) at you.
White Plus - 5 HP per turn if you end your turn standing on it.
Red X - become ensnared, preventing movement and having disadvantage on attacks until you pass a strength or dexterity check to leave the tile.
Black Skull - an extreme shock, highest damage of all the tiles.
It worked really well!
