Patch Notes: Revenant Stars

A star tree for each sworn revenant

Every sworn revenant now has its own star tree, built like the Firmament and the Captain's Stars. Open the Companions page (pause menu, Holdings) and press Stars on a companion's card.
The card shows its level and how many stars it has to set ("Level 3 · 2 stars to set").
Levels:
- A revenant earns XP from fights won at your side (more for stronger foes).
- It also earns XP from missions it comes home from (more for longer, more dangerous provinces), but only until level 10.
- It goes up to level 20.
Points: it gets one point per level after the first, and one per rank past the first. A Rank V revenant starts with 4 points to spend, and can reach 23.
When a revenant reaches a new level, a message tells you it has a star to set.

The Blade: health and damage. Its keystones are Deathless (+25% health, -10% damage) and Bloodrage (+20% damage, -10% health).
The Grave: its art.
- Stars make its art stronger (up to +40%) and its cooldowns shorter (up to 25%).
- Awakened Art teaches a revenant born without an art one of its kind's arts, at 75% of a born art's strength.
- Its keystone is Grave Pact (+15% art strength, -10% health).
The Road: missions and loyalty.
- Better mission odds, more gold and materials (up to +40%, never more gear pieces), and missions up to 15% shorter.
- Smaller loyalty losses and shorter rests.
- Its keystones are Fortune's Road and Undying Vigil:
  - Fortune's Road: +30% haul, but a mission that goes badly brings back nothing. It pays for a strong revenant and costs a weak one.
  - Undying Vigil: rests 30% shorter, loyalty losses 20% smaller, missions 10% longer.

It uses the same window as the Captain's Stars: click a star to take it and the stars on the way to it, and right-click to remove it. Changes are pending until you press Accept.
The QuickDial key asks before it closes a tree with stars not yet accepted.
Changing stars is free at any time, except while the revenant is abroad on a mission.
Health and damage change at once, and taking a star back takes its health back too.
A mission keeps the stars the revenant set out with.
The mission sheet shows each trip's length for that revenant, in hours when its stars shorten the road.
A revenant that deserts or betrays you loses its stars with its oath.

However many Menders are at your side, together they heal you at most once a minute (every 45 seconds with a fully hasted Grave).
A Siphon now gives you a quarter of the life it draws (it was a third).
Mending's cooldown is now given in seconds.
