There's a ton of cool Ki Bolt variants (like 13/4/3 FvS/WM/Monk has pretty much full healing w/wall and decent boss DPS via Ki Bolt, or the Monk/SF tank splits), but the best DPS I've come up with is 12/4/4 Wiz/Monk/WM as a WF - 38ish EK, 22 WM, 12 Harper, 6 HM, 11 WF.
EK gets both a bunch of melee power, a bunch of spellpower, boosts to both, and stacking buffs to both (a la Arcane Warrior, another great feat for these builds).
Chaosmancer gets immunity stripping, but Warforged has self-heals and 15 MP (and 25 USP with more racial AP) which is better if you bring a buddy.
This build scales with Crit Chance, Crit Multi, MP (not at 100%), and spellpower - and the best way to max those that I could find is EK, which coincidentally leaves you with passable melee DPS. I did wraps melee to test how it worked with imbue (pretty well), but obvs a style with +MP is better for Ki Bolt directly (and like Savant tree, but Harper is more DPS even if less Ki Bolt).
We were running Ice b/c better raid debuffs and pushing Fire raids, back with level 32 cap - I'm posting now because I don't think anyone is running Ki Bolt builds anymore. The big numbers are fun, but they're just highlight reel - and there's more to building than just single-target DPS, and these splits are pretty one-dimensional. Also Inquis has surpassed the DPS of this build (my best Cloud Giant bench was 76s, and even Alchy Inquis is down to 48s while also being ranged, way more survivable, and having better utility).
I also really like how accessible Ki Bolt is (not the numbers below, but the general theme - I was capping at like 60k on my healer split) to get newer players into better DPS as well; the endgame vets can already do better than this, but for a new player hitting 60k is a whole new world lol.
FS strike is also pretty decent, and Turn the Tide is decent for party (caster-heavy splits running T5 Magus w/Timestop)
If you're going to post screenies, get the real busted ones with a party's worth of buffs/debuffs too XD
Skeletons (Time Stop):
Biggest standard hit in FoM (w/TS):
Biggest non-TS hit (ice vuln boss):
Possibly biggest hit in DDO? (Rudus has like 10x negative vuln and we spent a few hours trying to coordinate buffs/debuffs for any devs watching this post, also building for negative DoT is a terrible choice in DDO):
I have video but don't really know how to blur names and voices etc out lol
13.6m from that ki bolt if you include the procs while dead (3.5m, 3.6m, and 1.7m for the other tics) - I mean it was super fun to oneshot Rudus and looks great, but also I was getting oneshot during setup, it's one boss in DDO, and there
was a lot of setup.
My best hit outside Ki Bolt is 300k without Time Stop, but that toon was significantly more useful in almost every way than this one. Actually survivable, AoE, CC, utility, etc. Single-target DPS not even much worse, and it was THF Barb.
Anyway Happy New Year's, hope this helps your quest!
