If i play a drow druid mooncaller, and i take the drow alternate trait of surface infiltrator, which takes away light blindness and darkvision and gives you low light vision, and the mooncaller at level 2 you gain nightsight, which gives you low light vision, if you already have low light it gives you darkvision and if you already have darkvision it adds +30ft to your darkvision. So my question is if i am a drow mooncaller lvl 2 with the surface infiltrator trait, would he gain darkvision?
