Ring Time

Ring Time is a skill that appears in Sonic Generations. It can be used only by Classic Sonic after he completes Sky Sanctuary's fourth Challenge Act, "Ring Time Challenge".

Description
This skill costs 60 Skill Points to equip. If it is equipped at the beginning of a level, then five identical symbols with a Motobug and a ring will appear in the top left of the screen underneath the number of Rings, along with an icon of the Y/Triangle button, which must be pressed in order to activate the skill. Once the skill is activated, Classic Sonic is surrounded by an atom-like "shield". This skill lasts for fifteen seconds, and any enemies that Sonic approaches during this time will be turned into rings.
