Mod Calls are special functions that can be used with tModLoader's
.Call() function to get or set different values from other mods. This page lists the Mod Calls that are provided by the Calamity Mod along with what they are used for.
Note that Rogue damage and Rogue crit are affected by vanilla Throwing stats, and adding to Rogue stats through these calls will add on top of any throwing stats the player is given.
An asterisk (*) after a parameter type indicates that the function accepts multiple arguments of that type at once. Optional arguments will be specified, along with their default value if applicable.

Some of the functions above mention accepting different aliases for the string parameters. One alias for each flag will be listed below in tables for each function, however alternatives that use different cases or spacing will still be accepted.
Some strings given here can be appended with _classname to get a specific class's version of that set bonus where appropriate (for example, statigel_summon or bloodflare_melee).
reaver_defense are used to refer to the Reaver Visage, Headgear, and Helms's set bonuses respectively.
- Providing incorrect or too few/many arguments to any of these functions will result in an ArgumentException being thrown.
