It doesn't matter if you AOE or not, arcane potency is effectively a 3% crit increase. The reason for the multiple procs is simply (and only) the high amount of hits.

This is correct. Arcane Potency doesn't have any kind of nonlinear synergy with TLC.

If you AoE 10 targets 10 times, Arcane Potency causes 3 more crits to appear (one the one Clearcast spell), which is exactly the same as what you see when you shoot 100 spells at one target.

While Potency does come out to be a 3% with most spells, this is not the case for AM spam. AM has a "double dip" type feature. Clearcast/Potency will proc when mana is consumed, which is at the beginning of Arcane Missile cast, and will last through the next spell to consume the clearcast. Thus granting Arcane Missile spam 30% crit increase for 10 missiles or 6% over all.

Ok there is a lot of talk about Mages here (guess they are the most popular caster crit class) but I myself am an Elemental Shaman...

I have been farming illhoof since our first kill and am Curious if anyone knows the number crunches for this.

On average atm I have 42% crit fully raid buffed, and cast at about 2 seconds (give or take with latency/Drums/Heroism)

I worked it out myself to be roughly 7 casts for a proc, and 14 seconds of cast time (in a desirable environment) So that is roughly 100 extra damage per cast?

Anyone back that up, or figure out just how much of a DPS increase that is?

Unfortunately this guy has been rather cruel, 5 months of zero LC drops... yeah

>.< I totally missed that.

Cheers

Our elemental shaman just got this a couple weeks ago, and loves it. He's also got a ~40% lightning crit, but the especially interesting uses aren't from LB spam. An EMed CL that procs LO (love those acronyms) will indeed shoot 2 proc bolts. Also, and especially, Magma totem builds charges, as does flametongue weapon, since both can crit. (That last bit won us an OOM-fest attrition battle in the arena against 2 paladins with an unexpected burst.)

Just tested on a mob, this is not true. Flametongue and Lightning Shield will build charges, totem crits will not.

Molten Armour builds charges too - its fun having melee duels outside raid zones and winning due to TLC and Molten Armour crits.
