Step two: build layout. Again looking at using a 18/2 wiz/rog PM mostly because I love me some removal spells here are some basic plans. Starting with Stats.
Keep in mind these are 36 point builds on a Fat Halfling Race (aka Dwarf)
Plan A
14 Strength
10 Dexterity
16 Constitution
18 Intelligence
08 Wisdom
12Charisma
Plan B
14 Strength
08 Dexterity
16 Constitution
18 Intelligence
08 Wisdom
13Charisma
Plan A vs Plan B: A has one less Chr but 2 more Dex meaning that there is no starting dex penalty to skills or AC (wanking motion to show how impressed I am with the new AC system) but Plan B will have +1 to Chr skills at odd tome levels ie +1 and +3 so more UMD and Intim aka both good things. Guess my Open lock and ninja skills will eat a -1.
Leveling layout, again this is with the plan of leveling to 20 as a PM.
Level 1 (Rogue)
Feat: (Selected) Insightful Reflexes
Level 2 (Wizard)
Feat: (Wizard Bonus) Empower Spell
Level 3 (Wizard)
Feat: (Selected) Past Life: Berserker’s Fury
Level 4 (Wizard)
Level 5 (Wizard)
Level 6 (Wizard)
Feat: (Selected) Past Life: Arcane Prodigy
Feat: (Wizard Bonus) Spell Focus: Necromancy
Level 7 (Wizard)
Level 8 (Wizard)
Level 9 (Rogue)
Feat: (Selected) Completionist
Level 10 (Wizard)
Level 11 (Wizard)
Level 12 (Wizard)
Feat: (Selected) Greater Spell Focus: Necromancy
Feat: (Wizard Bonus) Maximize Spell
Level 13 (Wizard)
Level 14 (Wizard)
Level 15 (Wizard)
Feat: (Selected) Past Life: Arcane Initiate
Level 16 (Wizard)
Level 17 (Wizard)
Feat: (Wizard Bonus) Heighten Spell
Level 18 (Wizard)
Feat: (Selected) Quicken Spell
Level 19 (Wizard)
Level 20 (Wizard)
Feat order might look a little out of order but what this layout does is allows us to take PM2 right at 14 and at the same time allows us to skip using Vamp form as the last thing you want to do at level 14 is start using a form that explodes when shot by a laser beam.
Also with just a little tweaking (swapping the Focus Feats) or none at all I could go AM and not PM until 20 when Lich form (aka the good one) kicks in. Tomorrow if I have time I will talk a little about maybe trying out AM for leveling up and why I am leaning that way at least until 20.
Finally the Main stat number, Int. Now this is not all fleshed out. Like I could take the epic +1 stat feats post 20 but for the most part this is everything I have or plan to get easily.
INT:
18base
+6level ups
+3enhcancements
+3tome
+2ship
+2yugo
+1litany once i get one (I like the raid)
+3insight robes
+8int goggles or ring
+2lich (going to assume PM at 20 for now)
+2completionest
+6 wizard destiny
+2 int twisted in from 2 other destinies
+1 int twisted Echoes of the Ancestors: Arcane (Magister)
+1 exp slotted some place easy
——
50 int normally running around with just yugo pot
+ 1-3 house D pots as needed (yeah right)
+1 when I find a +4 tome
+2 Store pots
+2 capstone if I go to pure at 20
I could go drow and have +2 more Int or Human and get +1 more. But really until Turbine makes an Int based Gnome I just like the Fat Halfling look. I mean have you seen their beards?
Well those are my thoughts atm, feel free to comment below.

the quantity of rated 5 votes? =)
I loved the fat halflings, and I have a wizard one.
Heighten at 17 and no Extend or Spell Penetration feats? I mean you try to insta-kill right? Can you do your Spell Penetration breakdown? 🙂
I would move PL Barbarian later (at 9+) and Heighten plus PL: Wizard earlier (at 3+). Ditch Empower (no sorcerer) for Extend (just for auras though makes haste/rage less annoying), PL Sorcerer for Spell Penetration (epic feats could allow Greater and Epic for a total of +8 nice for EEs). I like Mental Toughness too for Wraith which helps a lot with zerging but hard to fit with your layout unless you go pure.
Have you thought of using 2 Monk instead? You could fit 2 more feats (Toughness + Lightning Reflexes or whatever), ditch Empower/PL Sorcerer, fit the rest of 9 feats and add 3 Spell Pens + Extend (including epic feats). This would mean no traps/locks and less UMD, but better saves and hit points.
Is evasion really worth it? What about 1 arti and 19 wiz? You get to have a cute little minion! He can pull levers. Ever since arti came I’ve stopped the rogue splash, but then I always fail my saves – so evasion never helped.
Dwarks aren’t as lucky as halflings… (except the ones that fail their saves)
