Learnerheart in the simplest words is a cheat mod, allows you to level very, VERY quickly. It makes game a lot easier yes, but on the other hand, you can note that the game mechanics of Lionheart itself spawn more enemies when your character level is higher and also when travelling through crystal teleporters your character will encounter much higher level & more powerful opponents. Features also perks from Scion of Lionheart mod.
Learnerheart comes in three versions: Learnerheart base (very fast exping), Furyheart (furiously quick levelling up), and Stormheart (you practically get the 280 level (max level) with this at the very game beginning).
You can use any of above versions and their .exe files as a base for your own Lionheart modifications.
Two miniature mods for Lionheart: Legacy of the Crusader newly made (just the day before) and added to ModDB: Learnerheart and Scion of Lionheart. After playing Lionheart a bit, noticed that Lionheart has very few mods and only "rumours" of its moddability were around the vast Internet. That was the main reason to change things a little and make these two mods.
Right to the business, what does each mod change?
Both mods feature 280 character levels instead of just 70, and new perk ranks - almost every perk has now at least 4 ranks (in vanilla Lionheart most perks had only 1 rank), mainly to accomodate gameplay/exp levels changes.
What's the difference between the two mods?
Learnerheart is basically a cheat mod - it helps you level very quickly. The base Learnerheart version (or alternatively Furyheart) is recommended.
Scion of Lionheart is a small gameplay mod, designed to be an "elegant" modification with completely balanced & fair leveling system. You can still level your character up some 4 times faster than in the original Lionheart.
Downloads below, these two mods are tiny - each mod filesize is around 1MB. (No graphical/interface changes.)
