Description:

Gives Host a small chance to drop Host Hat.

Base chance is 0.1% (1/1000). This scales with Luck.

Items related to explosions also give a bonus chance, with potentially self-damaging items giving a bigger bonus.

Objectives

The main goals of this mod are to:

  • Make taking items that can damage you slightly less risky, and potentially more fun (eg. Bob’s Brain, Anarchist Cookbook)
  • Add an extra element of strategy to your build, by choosing explosion-related trinkets, hanging on to The Tower card, and acquiring even more risky items.
  • Give you a reason to kill Hosts that spawn from destroyed skulls, since in vanilla they’re effectively pointless.

Luck Scaling

The calculation is: 0.1 + ( LCK * 0.1 ), so just 1 point of Luck doubles the chance. At 4 Luck, it’s the same as the chance to get Dry/Ghost Baby from destroying a rock (0.5%).

Item Bonuses

All items related to explosions and bombs give a bonus chance, per item.

ESD = Explosive Self-Damage potential. These items have a higher bonus, giving you a better chance when you need it the most.

You can disable these bonuses by setting addItemBonus to false in the mod’s main.lua.

Modders

If you want to make a mod that does something similar (ie. make an enemy drop an item based on Luck/RNG), the main.lua file is heavily annotated. It also has an option to enable debug logging, which logs the RNG roll & drop chance after every Host kill, to both log.txt and the debug console.
