Someone asked to post my Warlock build so will put important aspects below, others might also get some ideas that might have missed for their individual Warlock builds or could even add some advice as might have missed something.

Build is a defensive, high dps blast aura Warlock that uses the Eldritch Aura for both defence and damage, should work with any of the Warlock Pacts, is not the max dps Warlock but is not far off, it has no dc casting at all.

Basics:
– Max Con and put +1 in at every level – At lvl 30 should get circa 70 con with tensers, this means with brilliance your aura gives all those around it incl. self 140 temp hp every 2 seconds, also shining through for self buff of 8xcon temp hp.
– Int and Char at 16, Int is important due to spellcraft damage for Light SP.
– Feats: Toughness, Empower, Maximize, Quicken, Extend, Shield prof, Shield Mastery and Imp Shield Mastery.
– Epic Feats: Epic Eldritch Blast, Intensify Spell, Wellspring of Power, Epic Damage Reduction
– Epic Destiny Feats: Epic Spell Power : Light, Epic Arcane Eldritch Blast and I went for Arcane Pulse as personal pref.
– Scion – Celestia
Skills: Max Spellcraft, UMD, Perform if Fey, Heal and Intim if want as can be handy
– Destiny: I go Sharadi as Exalted and Draconic need a bit more dc to be effective, is a solid caster dps Destiny.

Twists: Empyrean Magic: A must for any Warlock
Legendary Shield Mastery: With the feats u can reach a very respectable prr.
Radiant Power: +30 Light power
Cacoon

Enhancements: Full core ones in enlightened spirit, have spent 47 in ES, 9 in SE, 23 in TS and 1 in Human.

Main basic realistic gear would be:

At least a 2 Opposition set from Shroud items for +18% hp
2 slave Lords, with +17 con, Radiance 185, Dipl +22 and +4 Con, other False Life, Radiance Lore +27, Spellsight +22 and Qual Sheltering +11
Medium Celestial Armor
Lantern Ring, +6d6 Light damage still v good.
Cannith Crafting items/other named/LGS 1 hander should cover : Insightful Radiance, Insightful Phys Sheltering, Resistance, Char, Int, Insightful Con +7+,
Other Spell Powers and Lores depending on feats and Pact chosen and if can fit in extras such as heal amp, insightful Spellcraft and prob a few more all the better.
Shield: best option seems to be Epic Shield of Tireless Aid

3 past lives on Morningstar is also very handy for the +30 SP

Keep tensors Transformation and Displace up at all times
Healing Spring good source of Spell power

At lvl 30 I am sitting on:
200 PRR (combined with brilliance aura)
136 MRR
76 con buffed
3.5k hp with shining through
754 base Light spell power, boosted to just under 1k with all boosts effective: Empyrean, Wellspring, Tainted Spellcasting, Spell Power Boost and greater Brilliance pot.
Light Crit Chance : base 32 (this is why not max dps as other enhancement lines can boost this more) – does not incl Empyrean so +10 more pretty much all time
Light Crit: 89 (again other lines can add more, mine sits at this due to 4 LGS set, without this will be 60.)

I am going for the 5 piece LGS Enders set but the build was very solid a few lives ago without all the major gear, cannith and slavers will sort you for the most part and 2 LGS items is not too hard to aim for.
LGS 1 hander u can go for vacuum (but lots will have anyway in party), Radiance (my next one) presume Ice and ooze would work too.

Any questions or comments welcome.
