Have a Heart
Have a Heart is challenge #25. Isaac begins the challenge with Charm of the Vampire and 12 Red Heart containers, but only one of them filled. Unlike other challenges, Treasure Rooms and Shops are available. The goal is to defeat Mom's Heart or It Lives.
Difficulty[edit | edit source]
Charm of the Vampire is the main way to fill Isaac's Red Heart containers (see below for exceptions). All Red Heart pickups are replaced with Pennies (Half Red Heart = Penny, Red Heart (and Blended Heart) = Double Penny, Double Red Heart = Nickel) ( though Blended Hearts can still spawn). HP up items (e.g.: Breakfast) give Red Heart containers, but do not fill HP. The Lovers Card spawns Pennies instead of Red Hearts. The 2 of Hearts card and Yum Heart create no effect. The Tick will still reduce a boss' health, but will not heal upon entering the Boss Room. Shops sell coins instead of hearts. Slot Machines, Blood Donation Machines, the Hematemesis pill, and any of the beggars drop coins instead of hearts. Even a Super Secret Room which usually contains hearts will contain money instead. It is also impossible to recover health with Pyromaniac, Placenta, or Leech.
Strategy[edit | edit source]
The biggest difficulty lies in acquiring health. However, with numerous Red Heart containers, there are several strategies to survive the challenge. First is finding a way to heal Red Heart damage.
- The Full Health pill is a major boon for this challenge.
- XIX - The Sun card also heals to full health, alongside other benefits.
- Combined with a Blank Card, the challenge becomes trivial. This can be purchased from Shops.
- Obtaining the Habit or Sharp Plug from a shop allows Placebo or Blank Card to be used at will without any fear of death.
- Rainbow poop will also give full health, but it is also very rare.
- Bozo has a chance to create Rainbow Poop when Isaac takes damage, thus picking it up can make the challenge substantially easier.
- Beds still refill Isaacs' health.
- Adrenaline is very helpful as Isaac will have multiple empty Red Heart containers.
- Blowing up a Shopkeeper counts as an enemy.
Second is getting rid of excess Red Heart containers. Removing even one Red Heart container will make obtaining deals with the Devil and Angel Rooms much easier, as the open HP spot can hold Soul/Black Hearts, providing insurance against Red Heart damage.
- The Devil Room or Black Market deals not only give good items but also free up space for Soul Hearts. This, naturally, comes with the downside of preventing Angel Rooms from appearing.
- The Health Down pill can clear away some extra Red Heart containers to allow picking up Soul/Black Hearts. This can synergize with Placebo nicely.
- Guppy's Paw is one of the more useful items for survival because it removes hard-to-fill Red Heart containers and replaces them with Soul Hearts.
- Potato Peeler can be found in shops and easily removes excess empty Red Heart containers for Cube of Meats, Allowing you to easily get a couple of Meat Boys if desired.
A third method involves grinding enemies to replenish Isaac's health.
- Mulligans and their variants, Sacks and other spawning enemies can provide limitless sources of enemies to fill health.
- Getting the D7 and repeatedly clearing a room filled with easy-to-kill enemies can fill Isaac's entire HP bar.
- The Shell Game can be a useful method of spawning Attack Flies.
Because hearts turn into coins, Shop purchases are easier to make.
- Trinkets such as Bloody Penny, Burnt Penny, Counterfeit Penny, Flat Penny, and Rotten Penny are beneficial, as there is a greater chance of coins dropping when Isaac finishes a room.
- Bumbo and Bum Friend are also more beneficial with the increase in coin drops.
Some other things to note:
- If Isaac is at full health, the boss should take priority. Health lost during the battle can be replenished from unexplored rooms.
- Avoid using Hematemesis, as it will remove all but one heart without spawning two hearts as usual.
- If Isaac dies with a 1up!, all Red Heart containers will be filled.
- Judas' Shadow purges all Red Heart containers and leaves 2 Black Hearts.
- Mom's Locket refills half a heart each time a key is used.
- Acquiring an Eternal Heart will allow Isaac to take an extra hit. However, no health will be granted when acquiring a second Eternal Heart or moving to the next floor.
