Caps can be found on the forum, already gave links of of topics in which you could find most of the caps (also steiger made a topic with most of caps also)
But for +DMG% it’s only on weapons, which is a bit “normal”, your gear doesn’t deal any damage and you get only “armor” from them, not “dps”
However, +elemDMG% and +elemDMG+ can be found on any gear
