So Chronicle of Legends is on the srd now and there's some pretty interesting content; of particular interest to me is the Eldritch Knight support.
The prereq feat is a slightly more interesting Spellstrike, but Explosive Weapon is VERY cool and makes the EK an entry point to a type of character that was previously not possible. So, what spells do you prepare with this character? The easy choice is elemental evocations like Fireball and Lightning Bolt, but I'm curious if those more experienced with the Wizard spell list have other ideas for tricksy things you can do with this feat.
Parchment swarm with a scroll of frigid touch possibly, but a wider use might be an ordinary evocation with some metamagic applied - rime spell or dazing or apocalyptic or something.
It's basically a weapon attack plus a spell with the centered spell metamagic, but one interesting thing is that it doesn't reference the spell's casting time and it's fixed as a standard action. There may be some sorcerer/eldritch knights who find that useful.
Also if you have some effect on a weapon hit which penalises saves (cornugon smash, riving strike, whatever) that'd help.
A Silksworn Occultist would qualify, though I can't say with confidence that'd be worth it even with the Implement bonus. If nothing else it would be delayed by another two levels since you have to wait for 3rd level spells on a 6th level caster.
