This room is reminiscent of a bowling ball in two ways. First there are three small blood pools like the finger holes in a bowling ball. Second on a smaller scale, entrance 2 and 3 naturally lead to a major reward location surrounded by 3 thorn bushes in the same bowling ball finger hole pattern (which helps differentiate it from Chamber 1. Entrance 1, the small but circular pool of blood is distinctive and as you check the major reward location above, you will see the second pool that makes up 2 of the 3 bowling ball finger holes. Collect the upper reward and head to the bough. ​ Entrance 2, a hybrid of entrance 1 and entrance 3 visual indicators, you will see one blood pool and one thorn bush. Worst case you follow the trail to the bough, but ideally check the thorn-ringed reward before heading to the bough ​ Entrance 3, immediate see a major reward location surrounded by 3 thorn bushes. Collect the reward if its present and head to the bough.
