Lingering Potion and Dragon's breath particles causing lag

When fighting the dragon in survival, it shoots the dragon's breath. The particles of the dragon's breath is making the game lag so much. Even when I use 4-5 lingering at the same spot it creates similar effect as the dragon's breath and the game is lagging hardcore. I am using a OnePlus x running Android 6.0.1 with 3gb ram, 2.3 GHz snapdragon 801 processor, adreno 330 GPU.
