What is 'Proc Damage'?

[Fireplace]

I see the word 'proc' in various places, but never a definition. For reference in the Wiki on the 'staffs' row: https://te4.org/wiki/Item

What is 'proc damage'?

'Proc' describes all the additional effect associated to melee hits: +x fire damage on hit, or on crit, or spell casting on hit, etc, on either the target of the melee blow or on a radius around it.

The indication "2.5% Proc Damage" for staves, means that for every point that your dexterity exceeds the defence of the foe this additional damage is increased by 2.5%. This can be extremely powerful and can be the main source of damage for staff attacks.

Accuracy, actually, not dexterity. But yes, the rest of this is correct, and explained better than I could.

Dex does give you accuracy, but it can be gotten in other places as well, and usually most of it will come from gear or from Combat Accuracy. Depends on your build. If you're trying to build a melee staff user, and you want to make use of that proc bonus, you'll probably want to stat Dex for the extra. You'll want to put points into Combat Accuracy, too, but the Dex boost is sizable enough to matter in that situation.

Also, get a Perfect Strike pickaxe if possible when going melee procs. They are awesome for staff builds.

For what it's worth, the common pair of explanations is it's short for either Programmed Random Occurance or Procedure. Started popping up somewhere during early-ish MMO days. Meaning's more or less the same, just something that happens when you do something else. Used most often for stuff like automatically activating abilities or special item effects that kick in without direct player input, probably most often (but very much not always) as a percentage chance.

Practical effect regarding T4 in particular is covered well enough above, heh.
