Natural Selection
Every boon and tablet you find for the rest of the run has a greatly increased chance to appear as Rare or Epic.
Pairing
Why this pairing works
Natural Selection is the only duo that improves your run rather than your damage. Because it multiplies the rarity of everything you find afterwards, its value depends entirely on how early you get it — taking it in the final region is close to worthless, while taking it in Erebos can raise the entire run's power ceiling.
Playstyle
Recommended weapons
Aspect of Melinoë
Increases Omega move channel speed and raises both maximum health and Magick. The simplest Aspect to build around: more Magick means more Omega moves, and faster channeling means fewer windows where you are vulnerable.
Aspect of Melinoë
Speeds up the whole attack chain and adds substantial damage to the combo finisher. Directly patches the axe's main weakness.
Aspect of Melinoë
Increases critical damage across all moves and raises how much the shield absorbs. Reliable and easy to build around.
