Passive Skill Trees (Repentance)

XP, leveling, skill points and skill trees. Global passive skill tree + a personal skill tree for vanilla characters. These apply modifiers that can modify your run, from simple stat ups to gameplay-changing alterations.

• XP and leveling system, each character has their own level progress and skill points.
  
• Monsters grant XP based on their HP (XP is granted on room clear).
  
• Global passive skill tree with nodes you can allocate using skill points, which grant modifiers to the next run. Accessed from the character select menu.
  
• Global level and xp bar that all characters contribute to, which are the source of global skill points.
  
• Character-specific skill trees with nodes more correlated to their gameplay.
  
• Respec points which allow you to refund allocated nodes. Clearing a floor has a base 30% chance to award one. Can increase this chance through certain tree nodes.
  
• Can toggle tree effects on/off before a run.

You can access the tree screen from the character select menu, or in-game while paused, by pressing V (LT or LB on controller). Within the tree screen you can press H (or Select on controller) to get the control layout. The tree menu should have controller support but I've only tested on an old PS controller.

Bear in mind that making changes to the tree while in a run won't have immediate effects. Changes will be reflected in the next run you start.
(NEW to version 0.4.0) The new "Dynamic Tree Mode" global node allows applying allocated nodes to runs in real time.

While in the tree screen, press H to open the help menu, which has explanations for the mod's different features, including controls.

A very particular large node found in the global skill tree is "Cosmic Realignment" (which was originally a mod I wanted to make on its own).

Once allocated, you can pick (with an UI menu) any unlocked character and earn their unlocks while playing as a different character. There are a few downsides however:

• Node itself is locked behind multiple 'luck down' nodes.
  
• Each picked character has their own unique curse which will be applied to the run.

This de-incentivizes for example using a relatively easy character to go and unlock all of, say, tainted lost's stuff.
These unlocks grant a 'pseudo' blue completion mark to the target character so you may keep track, but original marks take priority, and thus isn't exactly a shortcut for an easier 100% file per se.

I've developed a small addon you can download that allows the mod to periodically create backups of its savefiles (which stores your levels, trees, etc.).
If data loss is detected and backups are present, a popup will show up when opening the tree that allows you to pick one of the backups to attempt to load.
You can find it Here[github.com].

This mod requires installing Repentogon. You may install it from here[repentogon.com].
NOTE: you need to install Repentogon following the instructions in the link for the mod to work properly, it's not just a workshop install!
Requires Repentance. Afterbirth+ unsupported.
Repentance+ DLC is not supported.

I have a little visual node js app, isaac-skilltreegen, that lets you create skill trees, and the mod supports coding skill trees for custom characters.
You can find the app's repo and releases Here[github.com]. Repo includes usage instructions on its README.

The mod exposes some API functions to initialize generated skill trees. Here[github.com]'s a reference guide for using it.
Example mod that showcases API usage.[github.com]

I've also been playing with the Siren character mod and this mod comes with a skill tree for her out of the box.

You can hover over the "Leveling Of Isaac" node (central node in global tree), and hold the Respec Node button for 7 seconds to reset ALL tree related data for your current save. Use with care!

The mod comes with a few debug settings which make testing its features easier. In the mod directory, main.lua file, at the top you can find a PST.debugOptions table with some variables you can set to 'true'.

There's also the PST_config.lua file, where you can find some extra settings such as whether to draw the xp bar, floating texts, char info in character select, xp multiplier, as well as re-configuring the keybinds used in the tree screen, in case of conflicts.

Supports Mod Config Menu Pure to toggle PST_config.lua settings.
