Eldritch Archer is a bit fucked up. The spells that can be used for Spellstrike aren't.. intuitive.
For example, Acid Splash and Ray of Frost can be used just fine. But Jolt can't. Now, you might say "But Luckmann, you fucking nazi retard, Jolt isn't a Magus spell, so suck dick". But neither is Ray of Enfeeblement, but that works just fine, and you can use wands for spellstriking (or should be able to use, I should say). Also, a major benefit of the Eldritch Archer should be that you can use Reach Metamagic to make spells like Shocking Grasp, Corrosive Touch, Touch of Gracelessness, or really any offensive touch-range spell, all of which explicitly become ranged touch attacks. But none of them seem to be working for ranged spellstrike.
And finally, as opposed to the other Magi types, for whatever reason, the Eldritch Archer can't hold a charge. This is extremely annoying, because if any of the other Magi don't get to expend their attack, they can just keep it charged until the next encounter and fire it off as they slap someone in the face. But an Eldritch Archer can't - if you move even the tiniest bit after your weapon has been charged with the ranged touch attack for spellstrike but before it has been fired, that spell is lost to the winds.
I'm not sure which of this is bugs and what is working as intended, but it all adds up to shit, either way.
Someone be a peach and report it to the faggots at Owlcat for me.
