Yeah, the whole idea revolves around "make the summon-able waepons at least comparable to tech'd weapons." This has to be accomplished by being able to add things that do stuff akin to techs/sockets, so.. procs, skill buffs, all sorts of other stuff. It'd basically shift KNoC into revolving heavily around their summoned weapon/shield, which seems to have been the nature of the class, rather than them just being a melee-type who can use a few summoning spells, as it presently stands.
As for Amon's post:
I think that list is a great basic idea. I don't think it's necessary to mimic *every* socket or tech possibility obviously, especially if a few options (such as the block-reactive shield heal) are unique, I think it'd be 100% fair to trade off the flexibility of normal socketed/tech'd gear for the flexibility of having fewer options, but being able to shift them around on the fly and having some unique/new ones.
Some "summong" type affects on the weapon might be neat - i.e. the 25% chance for damage type deal, to mimic ice hammer/flame spear, to keep with that theme. I'd steer away from some stuff like stuns or whatnot that may become too "Must have" and surpass everything else - the most interesting abilities when it comes to this sorta things are the ones that don't have an always-better-than-all-the-rest for every situation!
Some sort've ability-drain could be a neat sword effect - pull str or armor from the opponent (a transfer of matter, in the same vein as "banish armor"'s theme), possibly some + to summoning or casting skills if someone wanted to shore up their summoning spells a bit due to not being multiclassed fully. I think a shield heal-reactive would be neat, but don't think it'd fit on the sword, that's pushing a bit too paladin-ish side of things!
As for the shield: resistance/armor buffs, block chance buff, great, I think reactives when blocking are extremely spot on, especially with the shield being weird and ethereal and all.. Maybe even a few % chance on hit by spell type options? The KNoC could be something of a "mage-killer" type, considering their knightly magey mix!
