want to combine them into one seriously mean 6-linked combo.
so how about it, guys? help me out please. let's cook up something, together.

Lightning tendrils
Spell echo
Faster casting
Increased area of effect
Concentrated effect
Lightning penetration

Where did you self-find it?

Bog map. finally one random Inner Treasure monster that didn't drop instant vendor trash.
you could say I hit the dice twice.
yes, even I can get lucky sometimes. dumbly lucky.

@PsiBlades2002, sounds good. though isn't Conc Effect + Inc AoE wasting two slots to get one bonus?

Conc. Effect + Inc. Aoe is some mean mana multiplier tho.

I am running:

Tendrils + Spell Echo + Faster Casting + Added Lightning + Lightning Pen + Life Leech

It has a 90 mana cost compared to 130+ with Conc. + Inc. Aoe
You can also run Empower instead of Life Leech.
