Hey Ryou, I tried to fix the problem for the trade 1 soul bomb for 1 soul heart. Basically I changed the damage that the grey bomb do to the character from 1 full soul heart to half soul heart, making the character more playable! Still difficult to use (becouse you use half soul heart for "maybe" 1 new full soul heart, at least the trade is fair!), but now the playstyle fits more in the game, making him able to protect himself a bit from potential red heart damage, that will destroy all the chances for a devil's pact. For those who want to make this change, please follow the steps:

1) Go to (windows) Documents/My games/Binding of isaac Afterbirth+ mods/thecharred

2) open the main.lua file with any programs you want

3) Search for this string:

-- Deals extra damage to full soul/black hearts
if soulHearts + eternalHearts > 1 then
player:ResetDamageCooldown()

player:TakeDamage(2,DamageFlag.DAMAGE_INVINCIBLE,EntityRef(player),bombPlaceInvincibility)
else
player:ResetDamageCooldown()
player:TakeDamage(1,DamageFlag.DAMAGE_INVINCIBLE,EntityRef(player),bombPlaceInvincibility)
end
else
player:ResetDamageCooldown()
player:TakeDamage(1,DamageFlag.DAMAGE_INVINCIBLE,EntityRef(player),bombPlaceInvincibility)



4) change the value from the first "player:TakeDamage" to 1, it should be like this:

-- Deals extra damage to full soul/black hearts
if soulHearts + eternalHearts > 1 then
player:ResetDamageCooldown()
player:TakeDamage(1,DamageFlag.DAMAGE_INVINCIBLE,EntityRef(player),bombPlaceInvincibility)
else
player:ResetDamageCooldown()
player:TakeDamage(1,DamageFlag.DAMAGE_INVINCIBLE,EntityRef(player),bombPlaceInvincibility)
end
else
player:ResetDamageCooldown()
player:TakeDamage(1,DamageFlag.DAMAGE_INVINCIBLE,EntityRef(player),bombPlaceInvincibility)



5) Done! Now you take half damage when using a soul heart/bomb!



I hope it helped, I love the concept of the character, I made this guide only becouse I want to see it played more often from people :D

Note to Ryou: feel free to delete this post if you find that the change is too different from your idea of the character! Again, I'm just tring to help! But if this doesn't suit you nor your mod, I perfectly understand if you want to delet the post ;)


Cheers!
