Gives Isaac +3 damage and +1 luck for the rest of the floor.
Fully recharges Isaac's active item.
Removes any Curses from the current floor except the Curse of the Labyrinth.
Notes[ | ]
The buffs from Sol will be active upon entering all the floors in the Ascent, but it will not activate the effect of XIX - The Sun.
In Home, the buffs from Sol will activate after sleeping in Mom's bed or defeating Dogma's first phase.
Only damage and luck buff will be granted upon entering the boss room in the special version of Mausoleum II.
On floors with multiple bosses (The Void, XL floors, Red Redemption (challenge #44)), one random boss room is shown.
In The Void, only the randomly selected Boss room will grant Sol's effect.
Does not activate with bosses killed during Boss Rush.
Despite being on a different floor, Sol's effect persists for ??? and thus contributes to the Hush fight.
Upon defeating a multi-segment boss where all pieces die at the end (Chub, C.H.A.D, Carrion Queen, etc.), the effect activates once per segment, leading to an effective +3 luck and +9 damage until leaving the room, after which, the extra bonuses will be removed. It's probably a bug.
Sol will not activate upon clearing the Mirrored World's Boss Room.
If Sol is obtained in Greed Mode, through Spindown Dice or as a starting item for Eden, the effects will activate when entering the main room for the first time. In addition, it will activate each time a boss wave is completed.
Sol will not activate during the final stage in the mini-boss fight before Ultra Greed.
If Isaac manages to die at the same time he kills a boss, Sol will not save him. Instead, Isaac will die with full health.
Interactions[ | ]
The Battery: Provides an extra level of charge if the item was fully charged when the boss was defeated.
Tainted Lazarus: The item recharge, full heal, map reveal, and curse removal only occur if the character with Sol defeats the boss. If the boss is defeated by the character without Sol, The character with Sol still gets the damage and luck bonus for the rest of the floor.
"Sol" is the word for "sun" in Latin and some of its descendant languages, and is sometimes used to distinguish the Sun of the Solar System from other stars.
