If it is underpowered, suggest the player also use a feat on Sacred Geometry(quicken spell) so they can do it as a swift action instead, or some other potent metamagic- Intensified Spell is particularly popular for a shocking grasp magus. Not really worth taking for a 'poor man's scaling cantrip' though. Magus is the most obvious, but a Wizard or Sorcerer going for 'artillery mage' builds with Fireball get plenty out of it too. If it is within reason for your game, it is, in fact, RAW and can work fine. Either way, Wayang + Lineage are amazing traits for any spellcaster that's going to go heavy into metamagic on a specific spell. With the two traits its a +4 so uses a 5th level spell slot.

If this build is likely to be overpowered, consider applying the errata to magical lineage to Wayang Spellhunter as well, as e.g. With Intensified, Empower, and Maximize it does 60+(10d6 - 1/2) at level 10+. Note as well that shocking grasp is one of the weaker options for this combination- it just does melee damage- and that every spellcaster can have at most one spell specialized in this way. You should consider denying it on the basis of game balance, or suggesting/allowing your other players to use similar exploits. While the literal RAW of these traits is pretty clear in that respect, some GM's may feel it goes against the spirit of the rules (traits don't stack) and rule otherwise, so be sure to ask your GM. This follows the written developers intention for the Trait system. Running this trait in accordance with the rules makes it much more powerful than most other similar traits. Magical Lineage and Wayang Spellhunter stack, since neither are trait bonuses. I would think that since Wayang Spellhunter and Magical Lineage provide the exact same benefit, they don't stack. Just because the rules say something doesn't mean that is a good idea for your game. When you apply metamagic feats to this spell that add at least 1 level to the spell, treat its actual level as 1 lower for determining the spell’s final adjusted level. In combination, the two can indeed lower a +1 spell level adjustment metamagic to -1, which can indeed make a 1st-level spell a level 0 spell, which, for some classes including the Magus, gives it special properties unique to 0-level spells (like not getting used up when cast). Pick one spell when you choose this trait. Unlike Magical Lineage, Wayang Spellhunter was never errataed to prevent spell-level lowering.
