Purely as an intial line in the sand, these are my thoughts on itemisation:
head: GS conc opp, 25hp, 100sp
goggle: +8 Int, +13 disable device
trinket: tier 3 spyglass with toughness slotted
neck: charisma +7, greater luck (+5 resists, +1 good luck) - if you can get a major luck version thats even better
bracers: wind tier 3 with exc. Int +1; swap out to convalescant of sup parrying if not using tovens
cloak: dragon cloak
belt: +8 dex, +13 balance
gloves: PDK
boots: rock tier 3, with exc. Con and GFL slotted
R1: master artifice tier 3 with Con +6 and Heavy fort slotted
R2: avithoul (+2 insightful dex variant)
body: fleshmaker's docent with arcane lore upgrade (gives 10% heal amp amongst other things)
runearm: archaic (I prefer not having a huge bug on my arm lol) / corruption epic hard / tovens
There would be situational swaps as necessary, e.g. slot in deathblock of superior stability docent if needed; slot in +8 Int trinket and blindness immunity goggles of eagle +13 if needed; and so on.
This set up gives you +10/11 on dex and int, +9 to con, and keeps your cha and wis up to help with saves and umd. You have superior lore in elec and acid, and can completely swap out the relevant item if not using it (if going down this route, you'd slot GFL in both the bracers and the boots, as you'll be wearing one or the other at any moment in time). Heal amp can hit a respectable (for a wf self healer at least) 20% or so, and you'd only carry heal [i.e. no reconstruction] scrolls (which you could use to self heal for around 290 a pop).
There are places where the gear could be better, e.g. major luck instead of greater luck. Also, I'm missing out on planar conflux and therefore 50sp, and probably a few other things as well. Conversely, this build can hotswap tovens, corruption of nature, and archaic in any quest and still retain 85-90% of theoretical maximums for the runearm, whilst at the same time being able to throw decent blade barriers (as arcane lore is slotted separately to the runearm) and top of the line prismatic and tac det.
There is an argument to swap the docent out to blue dragonscale for an extra 3% BB crit chance, but you're trading 3% extra damage on BB for the other benefits of fleshmakers in that case.
The +8Int / +13 DD may look a little odd, but the spyglass covers spot and search full time anyway, so this way you don't even have to swap gear to fulfil trapmonkey tasks.
I originally considered ring of the stalker, but I understand that manslayer doesn't work on ranged attacks, so you lose +5 sneak attack for seeker +6, which is a bad trade imo - sneak attack is worth 8 damage per shot, whilst seeker +6 is worth 2.4 per shot on repeater.
The reason for slotting +1 exc Int on the bracers is that you hit 48 Int when using corruption without the +1 -
18 base + 4 tome + 6 level up + 3 enhancement + 6 ED + 8 item + 3 insightful (from corruption EH version) = 48
For tovens, you only +2 insightful INT from the spyglass, but you gain +1 from the bracers, to get you back to 48. If you want to keep this DC using lucid / archaic, you have to keep the bracers on.
