Power Shard deals only damage to one enemy, can be dodged and minion blocked and has really low range and a somewhat high cooldown until you get to level the other abilities. 80% AP is much, but most low utility mages have high scalings, a bit over the top maybe seeing as he only have damage abilities and its high base.

Thread of Wisdom "breaks" after hitting one champion. No matter how long it lasts, it will only either damage an enemy or heal an ally once per cast. The cooldown reduce of levelling W is what other champions would normally get from levelling any of his or her abilities, the main difference is that it is all from the same ability, the same way that damage is really low until you level Q and utility low until you level E.

Tricky Blast actually has the highest AP scaling, might tone that one down a bit too. You do get some nice utility from levelling E, but you either get it late game or are sacrificing damage and reduced cooldowns for it.

Light of Guidance has a 2 seconds delay, with the lowest natural movement speed of 325, you can easily escape it even if you are in the center of it on cast, and you'd probably have higher movement speed than that by the time Sesero reaches level 6. Even if it can be cast twice, hitting twice isn't exactly easy. Path of Wisdom upgrade might give really nice stats, but the entire team must actually be hit by the beam, forcing you to plan it carefully so the enemy team doesn't use the delay time to escape and wait it out, might also reduce duration so that such counterplay is better. Path of Trickery makes hitting a lot easier, making escape from the center require 1100 movement speed, flashing would still do the trick though.

Path of Power's on-hit is decent, might reduce slightly, building attack speed on a high burst mage is a bit wasted though, but a nashor's would probably work.

Path of Wisdom's assist and kill cooldown reduction is remaining cooldown, so it by itself can't refresh the cooldown completely. It also requires you to max W first, either trading damage for it or leaving Q at rank 4 and getting it late.

Path of Trickery is less useful (except the ult), I'll see if I can figure out something else for that one that doesn't go against going all in as much. Especially since the tradeoff of both damage and reuced cooldown is a lot.
