Fortress of Time->Times End : you are the heart of a glacier pulsing to the beat of aeons within your fortress you become immune to PvE damage and are encased in a large formation of stasis matter (think a ward of dawn but instead a ward of darkness) after what seems a millennia you shatter forth from your Stasis Coffin dealing x times shatter damage to targets based on their proximity to the caster. The remains of Stasis Coffin erupt like a porcupine of diamond lances in a dome of lances being unleashed at once. Exotic ideas: Chrono Brace gain maximum frost armour stacks upon exiting Times End. While you have stacks of frost armour gain grenade energy at an increased rate per stack of frost armour you have. Vex themed gauntlets that have an elaborate timepiece at the wrist that interlocks with what looks to be a pendulum from a grandfather clock on the end of the pendulum there is a sharpened sundial that looks like it’s got beyond comprehension levels of unbreakability (a pyramid ship tech looking sundial/blade). Secondary exotic effect harder to kill, frost armour has increased duration and stack count (+2 so with rime could max at ten) time duration on frost armour with rime doesn’t change but frost armour in prismatic would have increased functionality.
