Acceleration

This passive provides a N% speed boost per second(cumulative, not stacked).
Using diminishing returns formula(1% to 100%) a skill at level1(+1% boost) provides. Boost stops at end of movement sequence.
Original speed=100%
At level 1
speed at 0:01: 100% +1 %=101%
speed at 0:02: 101% of 101%=102.01%
speed at 0:03: 101% of 102.01%=103.0301%
at Level 10:
speed at 0:01: 100%+9.5617924991195%=109%
speed at 0:02: 109% of 109%=118.81%
speed at 0:03: 109% of 118.81%=129.5029%
