When a witch with the flight hex reaches a new level thresh hold, does she lose the previous abilities of the hex?
EX: When she reaches level 5 can the witch still cast levitate once a day and use featherfall at will?
Flight:
Effect: At 1st level, the witch can use feather fall at will and gains a +4 racial bonus on Swim checks. At 3rd level, she can cast levitate once per day. At 5th level, she can fly, as per the spell, for a number of minutes per day equal to her level. These minutes do not need to be consecutive, but they must be spent in 1-minute increments. This hex only affects the witch.
Yes, you gain the new ability at the specified level, but they do not overwrite the previous ability. You keep those.
The abilities are cumulative. At 5th level and beyond you have feather fall at will, the swim bonus, levitate once per day, and flight for 1 minute/level.
