What does this light purple bar at the bottom of the screen mean

First, the following tests have all been done with a Level 2 Berserker with no skillpoints or stat points invested on the dummy in the Estherian Enclave. Critical hits and fumbled attacks are completely excluded from every calculation aswell as attacks from both claws at the same time.

Secondly, this was an interesting thing to test and I'll have to explain a few things/assumptions before I get on with the more related results:

How random is the damage ?

Assuming a constant environment I would assume a constant damage result. This is however not the case, and thus all results by me (and others) will be subject to 'random' fluctuations. I tested this with a 45 dps claw (36 physical damage every 0.8s) which gave me a weapon damage of 39-39. I used no offhand and proceeded to hit (regular attack) the dummy like a madman. I hit either 34, 35 or 36 while i would have expected to hit 35 all the time.

How to account for armor?

In Torchlight 2, every damage you do is decreased by an amount based on the armor value of your enemy. Since all the damage in my tests was Physical Damage, we can focus only on physical armor, but there's no way of knowing the armor of your enemy as far as I know.

When I hit the dummy with my regular claws (13 - 19 weapon damage) I had hits variating between 10 and 17. Removing 1 claw gave me 12 - 18 weapon damage and hits between 9 and 16. I then equiped my high dps claw which gave me 39 - 39 weapon damage and got hits between 34 and 36 (avg. 35).

From this I concluded the damage decrease done by the dummies armor for this range of damage is between 2 and 4.

Note that I by no means claim that armor removes a linear amount of damage nor that it doesn't scale with your damage, level, ...

Is everything an integer ?

That would be nice, but sadly: no. A lot of calculations gave fractions/floating point numbers as a result. Since it's not very nice to display those everything has to be rounded to an integer. I do not know how it is programmed, but I assumed everything is rounded to the nearest integer. This seemed to be most of the time the case.

Now, let's get on with the real results!

Scenario 1: 1 claw, no offhand

With 1 claw in your righthand and no offhand, this does exactly as it says: it takes your claws dps, takes 88% of it and deals that amount as damage (the final result still has to include armor!). So the higher the dps of your claw, the higher the damage of Eviscerate will be.

With my 45 dps claw I mentioned above, my Eviscerate hit for 37 - 39 (avg. 38). Indeed, 88% of 45 is 40. Giving this an armor penalty of 2 gives us the average Eviscerate damage.

Important to note is that this is an increase of damage compared to a regular attack. (an increase of 3 damage in this case)

Scenario 2: 2 claws, equal dps

Now, how does the damage compare to scenario 1? Does it increase because of dual-wielding, is it the same, does it decrease?

• With 1 claw of 22 dps I got Eviscerate hits of 12 to 20 (avg. 16).

• With 2 claws of 22 dps I got Eviscerate hits of 14 to 21 (avg. 18).

Tada ! An increase. But by how much and why? I will return to this at the end of scenario 3.

Scenario 3: 2 claws, different dps

This is the part where it really becomes interesting.

• A 45 dps claw in right hand and a 22 dps claw in offhand gives me 41 to 43 damage hits.

• A 22 dps claw in right hand and a 45 dps claw in offhand gives me 14 to 21 damage hits.

So it's of the most benefit to ALWAYS put your highest dps weapon in your right hand.

Now with that last result in mind, we return to scenario 2, where we got the same damage as with a 22 dps claw in our offhand (twice an average of 18). So the stats of our offhand are not important, as long as it's a weapon (see later: shields) you will gain an increase in damage because of dual-wielding.

So how much is the increase for dual-wielding? I don't know but from these results it would seem like the increase is equal to floor(dps of righthand / 10):

• 22 dps claw gives an average of 16 damage per Eviscerate hit

• 22 dps claw with an offhand weapon gives an average of 18 damage per Eviscerate hit

• 45 dps claw gives an average of 38 damage per Eviscerate hit

• 45 dps claw with an offhand weapon gives an average of 42 damage per Eviscerate hit

In the first case we see an increase of 2 and in the second case an increase of 4 which could be explained by the formula.

So we can just equip a shield as offhand for better survivability?

No, the damage output will be the same as if you had only a claw in your right hand (a la scenario 1).

But the increase of damage by dual-wielding is very little, why is it worth to dual-wield then?

This was done at level 2 and with no multipliers, skills... so the damage increase by dual-wielding should scale better at higher levels, better gear/skills...

I hope this answers most of your questions!

If you save and exit while in a phase beast challenge, then when you start up again, you'll be at the beginning of the challenge, but still have all of the items you got from it before. Thus, you can farm a challenge repeatedly this way. Make sure before you go in that you have plenty of inventory room, both yours and your pet's.

Note that this only works in single player, as you'll always restart in town while in multiplayer. And once you leave the phase zone, the only way to try again is to reroll the map and find a phase beast again (which might not give you the same challenge).
