Risk of Rain 2 - Survivor Mod Idea: Hollow Knight

Hollow Knight

Description: based on Hollow Knight created by Team Cherry

Passive: Soul Meter
Primary and Utility will gain soul upon hit. Soul will heal Hollow Knight when out of combat. If Hollow Knight is killed with full soul, he will be revived into broken soul. Using Secondary or Special will automatically consume soul to reduce cooldown.

NOTE:

• Maximum 99 or 66 soul.
  
• If the player is killed with 99 soul, then revive the player, set to 0 soul and maximum soul reduced to 66.
• If the player has 66 maximum soul: On entering next stage, a player's Umbra will spawn in the map (like the one via Artifact of Vengeance), if the Umbra is killed then restore maximum soul to 99. Do not work when killing the Umbra spawned from Artifact of Vengeance.
• Only spawn 1 Umbra for 66 maximum soul, even when multiple player is having 66 maximum soul. The Umbra will scale accordingly.
• Each enemy hit using Primary or Utility will add 11 soul
  (If Visions of Heresy is acquired, the initial hit will add 1 soul and explosion will add 10 soul).
• Using Secondary or Special will consume 33 soul and reduce cooldown to 0.5s. 
• Reduce cooldown only works when having 33 soul or above.
• Reduce cooldown also works for Hooks of Heresy and Essence of Heresy.
• When out of combat (same as Cautious Slug), consume 5 soul to heal 5% hp on each second. Start at 1% at 0 second, then 1% each 0.2s.
• If changed into Heretic, lose the entire Soul Meter passive.
