This is an effects pack that can be used for all kinds of rpg or fighter games as "weapon trails" or similar attack/elemental effects. Fire strike, ice strike, etc. The effects are not trails (they don't actually follow the sword/axe/whatever), but models with a fixed shape with added particle effects and scripts.
The goblin character is also in the pack, but lacks animations/mechanim setup, so it might be not useful to you; this package is about the various strike effects.
