Using Shady in battle will summon Sisyphus and Bouldy to aid you. Sisyphus will drop from the sky, slamming Bouldy into the ground in front of you and dealing 1000 damage in a wide area. Bouldy will drop a care package of , , and , before disappearing.
Bouldy will automatically target the closest enemy to Zagreus, albeit it can still miss, as it has a delay of sightly under a second before landing (the landing point is visible by a shadow similar to that of a Skull-Crusher). Its targeting also has a very short range (just barely above melee) and will instead drop (harmlessly) on top of Zagreus original position if no target is detected. As a result, it is recommended to use Shade against non-moving enemies or when Bosses are standing still for certain attacks and to aim it properly by standing almost next to the desired target.
Rewards in each care package:
Despite not being chamber rewards, the resources dropped are affected by boons such as Ocean's Bounty, Eclipse or Nourished Soul. Aggressive usage of Shady with several boons (especially several stacks of Eclipse) can add a modest amount of which can be useful in farming runs. If used in this manner, it is recommended to save the casts for Styx, where the player has already stacked as many boosting boons as possible, while also buying the Night Spindle wherever it's available.
Notably, Shady and Rib are the only companions usable against the final boss before meeting certain conditions. Additionally, Shady has absolutely no other restrictions, as even Rib cannot be used against Charon. As all companions, it cannot be used outside of combat.
