What Is Cursestacking / How Does One Do It Effectively

I've seen a build where a person commented that cursestacking improves the damage a lot. What is curse stacking and how does one properly use it?

 

When you use Time Rift (or any item with the Sorcery Major ID) to re-cast Curse multiple times.

 

using superslow makes your powder special charging easier if you have a spell build

 

How many times can one stack curse normally?

 

mainly two times and sometimes three

@RenZenthio knows stuff about this

 

This is the damage bump on average from a sslow weapon:
Sorcery curse gets you on average +656% on archer, +492% on non-archer Sorcery courage gets you on average +416% on archer, +312% on non-archer
(For curse: 3.1 curses on average for archer, 2.3 curses on average for non archer
For courage: 2.8 courages on average for archer, 2.1 courages on average for non-archer)

To effectively utilize, hold shift and weave melees into your spell cycles, and stay within melee range and curse range if using curse

Here's a video I did on it:

 

Great video! The explanation was great.
