Upgrade the Duration Stat for Sonic Blast & Heal

You ought to be able to upgrade the duration for a lot of spells particularly the Sonic Blast and Heal spells.

the max pearl upgrade is what 30%? So we might get a few seconds after thousands of pearls. What I would like is no cap on pearl upgrades and ratios that are real and measurable (I.e. no .01 % increase only 0.1 and higher)
