Requires Unity 3.5.7 or higher.
More than 40 dynamic, sophisticated effect prefabs. Each effect consists at least 3-4 individual particle systems, some have additional scripting and 3d models. The effects use "realistic" scaling, the figure in the demo is about 2m tall.

The particle systems use the "legacy" particle systems (older ones, from before unity 3.5). If you need them scaled, there is an excellent and inexpensive effect scaler here:
