Well all righty then... maybe consider these.
Don't use 2 fgt, use 2 arti or 2 druid
You're giving up way too much because you want to use heavy armor. You need AP into elven arcane dexterity and a 15% asf item (assuming you're not using twilight/greater twilight gear).
I suggest dropping the armor all together. If you're not of class, your AC will be lacking even if you put on the heavy gear.
1 druid: wolf companion (stacks with summon), 2 druid: bear form (useless)
1 arti: Disable traps, iron defender, 2 arti: Rune arms.
I suggest 2 art. You get a summon stackable iron defender and access to rune arms. Your int will also be high enought to allow you to disable traps.
If you truly want to continue using armor, you can use a blue augment slot's agile casting. 15% asf reduce. Probably better than limiting yourself to twilight heavies.
Albeit, the best heavy armor you can don as a wizard is:
Epic Cavalry Plate
With the new crystal cove update, the cavalry plate is going to get an upgrade. I'm thinking it'll upgrade the DR 5/chaos into DR 10 or 15 / Chaos.
The plate also comes with a blue aug slot, for your arcane dex 15% asf and if you also use elven agile cast, you can use this plate with no ASF. The proficiency on the plate, however... will be lacking.
Shadowmail is not a good option because all its stats is made redundant by Twilight , which; is probably the end game item of your type of build.
Don't use elf. Use human.
Your reason for using elf was to put ap into spell dex (for asf) / spell pen. It's not worth it.
If you use elf, you're 2 int behind drow, 1 int behind human.
As a human, you also get an additional feat slot and more hp than drow or elf.
And, since you'll be running around alot, you'll need more hp till your heal yourself up or enchant something.
Epic wolf whistle
A swapable clickie to summon the strongest cl 35 summon in game. Albeit still pretty useless.
Shard of xoriat
Use to get chaos beholder which is way better than hezrou summon. Albeit still useless in the end.
Epic roderic's wand
You can use this in place of summon augmentation. If you swap on before you summon, your summons will get summon aug. You can then save another enhancement slot.
You should use lich form not wraith form.
If you need incorporeal, use Cloak of night lv 24
Wraith form is not good enough.
Lich form you gain: You shroud yourself with negative energy and assume many traits of a lich. While in this form, you gain +4 Constitution, +2 Intelligence, Wisdom, and Charisma, and +1 to DCs on your necromantic spells, inflict wounds with your unarmed attack, and occasionally gain temporary hit points when damaged
Pretty much +1 necro, +2 int, +4 con (wis & cha as cake) and a main hp shield when hit.
The rest is up to you. But, if you want to remain pretty tanky. Use Epic robe of shadows (cl 24), bracers of demon consorts (demonic shield), and a green steel concordant opposition item.
These, especially boon of undeath and demonic shield will make you pretty tanky because they proc a LOT.
Also, twilight would be good if you're going enchantment heavy. It will also cover your spell pen issues with arcane augmentation and if you use a planar conflux, you can gain another lvl 9 spell pen.
I'd suggest you go primal avatar as your main.
Elder dryad summon is a lot better than a lich or succbi summon from magister's (grand summoning).
Also, natural shields and the oncoming storm / summer smoke / spring, will make your mobs a lot stronger.
You can twist magister's.
t1: Sigil of Spell Warding
Sigil of Spell Warding: Active Ability: (Cooldown 30 seconds) Inscribes a sigil for 60 seconds. Grants [1/2/3] AC and [5/10/15] PRR. Only one sigil active per caster.
t2: [Spell School] Specialist: Passive Bonus: +[1/2/3] DC to chosen school. (Necromancy or enchantment)
t4: Call Kindred Being: Active Ability: (Cooldown 60 seconds) Summon an epic (CR20) creature to aid you. Although it's not mentioned in the icon's description, this ability costs 20 spell points to use; summoning the succubus has a spell point cost of 0. The creature type depends on school familiarity as follows: Abjuration summons an Animated Armor, Conjuration summons a Golem, Enchantment summons a Succubus, Evocation summons a Living Meteor Swarm, Illusion summons a Dream Reaver, Necromancy summons a Lich, Transmutation summons a Gargoyle.
If you do not like call kindred, you can:
t1 Exhalted angel Endless faith - Gives your around 300 more sp and 30 sp minimum sp regen.
t1 Shiradi Healing spring for around 100 heal per 20 secs to your mobs
t1 Fury of the wild Boulder toss for around 500-1k dmg boulder every 20 seconds.
You will have enough fate pts to twist a t4, t2, and t1 (or, t3, t3,t1) if you have all lvl 5 eds and a +2 fate tome from ddo shop.
In all honesty, I never recommend enlarge, or extend. I just find them so very useless.... but, maybe u want to extend your dominate monster or what not.
With all the additional feats you have, (by going human and not taking summon aug + extend):
You can add up to a "greater spell pen".
Quicken is a must.
Empower is a must.
Insightful Reflexes is a must.
Past Life: Arcane Initiate is a must.
Past Life: Arcane Prodigy is a must.
For your build: Past Life Bardic Dilettante is a must.
With these considerations, your build might just be able to limp by an epic. Albeit, the rest of the party will hate you for all the summons and dominated monsters.
Just get that dismiss charm ready.
Also, if you think I'm bitter and discouraging.... you might get worse if you bring this build into a raid. Especially with non-dismissible summons...
