/calerts mode {all/pvp/pve}
all - Will show alerts for both PvP and PvE encounters
pvp - Will only show alerts for PvP encounters.
pve - Will only show alerts for PvE encounters.
Note 1: Enemy/death alerts will always be shown, no matter the mode.

/calerts modify {damageratio/healratio/distractratio/assist} value
Allows you to modify the damage ratio, heal ratio, distract ratio, and assist time window.
damageratio - The damage ratio is a percent in decimal format. So, for example, 0.55 is the value, and it represents 55%. If damageratio is 0.55, then you need to do at least 55% of the damage to get credit (and thus see an alert).
distractratio - The distract ratio is a percent in decimal format. So, for example, 0.42 is the value, and it represents 42%. If distractratio is 0.42, then you need to have taken at least 42% of the damage from the now dead enemy to get credit (and thus see an alert).
healratio - The heal ratio is a percent in decimal format. So, for example, 0.3 is the value, and it represents 30%. If healratio is 0.3, then you need to have healed an ally who has killed the now dead enemy 30% of the damage that the ally has taken to get credit (and thus see an alert).
assist - The assist, short for assist time window, is a number that represents seconds. So, 6 is the value, and it represents 6 seconds. All damage done and alerts shown are only applied for the last X seconds of the match (before the enemy died), where X is assist.
Note 1: These values apply both to allies and enemies.
Note 2: Modifying any value here will change your configurations but not your profile. To save these values to your profile, use /calerts saveprofile ProfileName

/calerts {loadprofile/saveprofile/deleteprofile} value
Profiles hold the damage ratio, the distract ratio, the heal ratio, and the assist ratio.
loadprofile - Will load the specified profile.
saveprofile - Will save your current settings to a profile. Can be loaded account-wide.
deleteprofile - Will delete the specified profile.
Note: saveprofile will overwrite an already existing profile without warning you.

/calerts defaults
Will set damageratio, healratio, distractratio, and assist values back to default.

/calerts modifytext {title/message} {victory/death} {solokill/killingblow/damageassist/distractassist/healassist} value

victory/death - Specifies if you want to modify the text for a victory (i.e. allies), or a death (i.e. enemy).
solokill/killingblow/damageassist/distractassist/healassist - Specifies exactly which message to modify.
value - The new text. Do note that {1} represents the name in all messages. In messages with two names, {1} is the first name and {2} is the second name.
Note: Modifying any text here will change your configurations but not your text profile. To save these values to your text profile, use /calerts savetextprofile TextProfileName

/calerts {loadtextprofile/savetextprofile/deletetextprofile} value

Extended Alerts is off by default.
