Nasus ages his target, slowing their movement speed by 35% and reducing it further to reach 47 / 59 / 71 / 83 / 95 % slow at the end of 5 seconds. The target's attack speed is also slowed by half the amount, initially slowed by 17.5% and increasing to 23.5 / 29.5 / 35.5 / 41.5 / 47.5 % over the duration. If the duration of the slow is reduced, the extra slow will be applied faster for it to reach its maximum at the end of the duration.
