Well, I checked when he lost his mana burn (V1.0.0.96), and even when reworked it was different (extracted from the patch notes) : The active has then been changed to what we currently know in the V1.0.0.120.
 * has been redesigned:
 * Passive: Now restores a flat 4/8/12/16/20 mana with every hit and triple this amount when the hit is against champions instead of removing 2/2.75/3.5/4.25/5% of his opponent max mana and restoring twice that amount to his own mana.
 * Active: Upon activating the ability Kassadin gains 7/15/25/38/50 armor penetration for 5 seconds.
 * 15 second cooldown.
 * 30/40/50/60/70 mana cost.
 * Activating this ability counts as a spell cast for the purposes of.
