Here is a more generic list of traits I always try to get. Although I play Arcane I do believe that for the most part these are some strong traits for the specs.
PRIORITIZE FOR LAST BOSS (IF ARCANE):
(To see a way to nuke the last boss with relative ease read my post above . . . these anima powers are the three important ones for that strat)
Runecloth Wrappings — The damage of Arcane Blast, is increased by 2000% when you cast it while Invisible.
Seeker’s Scroll — Breaking a Destructible Object increases the damage of your next Arcane Blast by 10%. This effect stacks up to 100 times.
Alluring Cheese — Your Conjure Refreshment also conjures Alluring Cheese, luring up to 3 neutral Mawrats.
OVERALL DECENT:
Spellweaver’s Mojo — Your Fire, Frost, and Arcane spells cause the target to take 30% increased damage from your other two elements for 8 sec.
(Paired with) Fire Juggler — Your Fire Blast launches your enemy into the air.
I personally really enjoy Spellweaver’s Mojo. It can provide significant buffs to AoE or Single Target. I could see this being very good for Fire/Frost AoE by using Arcane Explosion before Flamestrike/Blizzard/Frozen Orb.
For AoE while playing Arcane:
Touch of the Magi—>
Frost Nova to apply power—>
Arcane Barrage—>Arcane Orb—>Arcane Barrage—>Arcane Explosion
For ST:
Touch of the Magi—>
(Frost Nova)—>Fireblast to apply power Arcane Missile Spam or Arcane Blast—>Arcane Barrage—>Fireblast (repeat)
STRONG PASSIVES:
Archmage’s Ultimatum — Arcane : Gain the Overpowered talent.
This allows you to take both: Overpowered and Enlightened
Archmage’s Lesson — Gain the Incanter’s Flow talent. If you already have this talent, you may select another talent in the same row.
This allows you to take both: Incanter’s Flow and Rune of Power
Mad Wizard’s Intellect — At the beginning of each floor, you will receive an intuition, telling you to cast a series of spells in a certain order.
If you successfully cast these spells in the correct order, your Intellect will be increased by 10%.
VERY HELPFUL (CC):
Polymorbid Rat Liver — Teaches you Polymorph, which works on Undead creatures.
(Pairs well with) Tome of Zoomancy — Polymorphed creatures regenerate health 75% more slowly, and the first 3 damaging attacks or spells that they receive do not break the effect.
This truly will save you on some upper-level floors with large packs full of Elites . . . it isn’t so much needed on the lower-levels, but it can definitely be helpful if you are undergeared or having damage/survival issues.
SURVIVABILITY:
Secret Spices — Killing a Mawrat increases your maximum health by 2%, up to 100%.
Resolute Medallion — The absorb of your Barrier spells is increased by 50%.
Triune Ward — Casting any Barrier spell grants the effects of Blazing Barrier, Ice Barrier, and Prismatic Barrier.
Protective Phantasma — Looting Phantasma grants you an absorb shield for 65 per Phantasma, up to a maximum of (1 * Total health). The absorption stacks, and lasts 5 min.
