ARCHON SHARDS
2 cast, 3 duration

• [Spectral Spirit] gives approximately 30 seconds intervals of absolute immortality, separated by a cooldown of 25s reduced by 1s per kill, meaning you can fully reset cooldown after getting just 25 kills (potentially in a few seconds). This allows you to effectively have 95% uptime of immortality, crit damage buff, auto application of doom, while also generating health orbs on every kill giving extreme energy economy.
• [Catalyzing Shields] or [Rolling Guard] are both optional depending on preference. These are obviously NOT useful while [Spectral Spirit] is active but are very useful during the cooldown if you become overwhelmed by enemies and need to shield gate conventionally, and are especially recommended for solo. Flexible between Augur Message + Constitution if you prefer.
• The subsume slot is either 4 for a damage buff such as [Xata]'s Whisper, Eclipse, Roar, Nourish
