In the Single Player forum, I play in a tournament where the characters are not allowed to invest any skill points. I play an assassin that has reached Canyon of the Magi in Hell. She uses Langer Briser as main weapon (mainly for the Knockback and Open Wounds) and has a claw with bonus to BoS and CoS on the weapon switch. She usually wears a 'Rhyme' shield together with that claw, but in areas with resurrecting monsters she dual wields claws, adding one with +3 to Death Sentry.
Anyway, the main damage is dealt by Sharyn, her fire rogue merc. Sharyn uses Guillaume´s Face, a 4s armor with an IAS Jewel and two big lightning damage jewels. Her bow is my Hell imbue and it looks like this:
Bone Loom
Great Bow
Two-Hand Damage: 31 to 138
Required Dexterity: 107
Required Strength: 121
Required Level: 51
Bow Class - Very Fast Attack Speed
Item Level: 83
+166% Enhanced Damage
+195 to Attack Rating
Adds 1-28 lightning damage
20% Increased Attack Speed
5% Chance to cast Level 1 Amplify Damage on striking
Not the biggest and baddest, but I think it´s got style and it gets the job done.
