Effective DPS
Target resists allow you to specify the resist profile that your DPS will be checked against, allowing you to determine effective DPS depending on which ammo / weapon system you choose.
It is easy to select your target's resists. You must already have some resist profiles saved (see below). Simply right click the Firepower pane and select:
As you can see, (Effective) will be displayed if there is an active resist profile, allowing you quick visual clarification in case you notice your DPS is slightly off
You can add target resists much the same way as damage profiles: Window > Target Resists Editor or use the shortcut Ctrl+R
You can manually add profiles with the action buttons or import a list of pre-defined values from clipboard (see below).
To better facilitate organization, you may prepend the name of a profile with a group name in square brackets like so: [Parent] Child. In the context menu when selecting, the parent item will include a child sub-menu (see first image). It should be noted that this feature is not recursive: a profile names [Parent] [Child] Grandchild will be constructed into this menu: Parent > [Child] Grandchild.
Copy this to your clipboard, and select the Import from clipboard button in the Target Resists Editor
