Isaac Rebuilt
Isaac Rebuilt is a challenge added in The Reheated Update. In this challenge, the player starts as Tainted Magdalene with
Sanguine Hook,
4.5 Volt,
Birthright,
The Belt, a blindfold, and
Yum Heart in their pocket slot. The goal is to defeat
Mom.
- The Sanguine Hook Tainted Magdalene starts with in the challenge is latent, and replaces the ability to fire tears. It cannot be rerolled or removed.
- During the challenge, Sanguine Hook has the unique ability to drop a few temporary
Half Red Hearts when killing an enemy from pulling out the hook, which disappear after a short time.
- Enemies killed via hemorrhaging applied by Sanguine Hook won't count.
Difficulty
- The player cannot fire any tears, requiring them to use Sanguine Hook and Tainted Magdalene's lethal hugs in tandem to kill enemies.
- The addition of 4.5 Volt can make healing with Tainted Magdalene's Yum Heart to staunch her draining health generally less reliable outside of boss fights.
Strategies
In general, the strategies of playing Tainted Magdalene apply to this challenge as well; with very expendable health early in the run means Tainted Magdalene will usually be charging into groups of foes to slay them with her lethal hugs, while also maximize healing return from the amount of Heart drops gained while doing so.
Boss fights will be the player's main focus point, however, as this strategy is less useful against enemies with too much health for her hugs to handle swiftly. As Tainted Magdalene's tears are replaced with hooks during this challenge, learning how to use Sanguine Hook effectively is essential for completing the challenge alive.
- Because enemies become bruised while dragged by the hook, it may be wise to keep a hook on an enemy so Tainted Maggy can close the distance and deal the increased damage with her hugs, if an enemy needs to be finished off more quickly.
- Sanguine Hook can drop additional temporary Red Hearts when an enemy is killed by the hook being pulled out. However, this can at times be unreliable if the first hook doesn't kill them outright, as enemies can be killed by the hemorrhaging before they die from a hook pull.
- As Sanguine Hook can pull in pickups from a distance, it can help Tainted Magdalene grab Hearts before they can disappear.
- While 4.5 Volt can be a detriment to Tainted Magdalene's ability to use Yum Heart for regular combat scenarios against fodder enemies, 4.5 Volt becomes a potential boon for Tainted Magdalene's longevity during boss fights, as it can potentially allow using Yum Heart multiple times during them.
