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.
Simply create the prefab with the Instantiate command (example scene added), and the effect plays and destroys itself. It is a great out-of-the-box solution for any RPG, MMO, or even strategy and FPS game!
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:
