Turns out there is. I just got an item from the Post Game Labyrinth stage that lets me forget all of my skills and assign the points again.
It's called Amnesia Elixir.
That's good to know. That might be a good opportunity to experiment with different skills before committing to a particular build.
Also does anybody know what the stats Con, Dex & the others do?
And what does Retribution mean in the game? And 'Chance to counter with Ice'?
Strength (STR) - Affects physical damage. Good for every class except sorceress and wizard.
Intelligence (INT) - Affects magic damage. Obviously, it mostly benefits the sorceresses and wizards. It can be useful for elves who use Elemental Lore. Worthless for everyone else.
Constitution (CON) - The higher the stat, the less damage you take from physical attacks.
Magic Resistance (MGR) - It works the same way as CON, only with magic.
Dexterity (DEX) - Every weapon has a certain range when in comes to damage. The higher the dexerity, the more likely your character will hit at maximum damage. If a weapon hits for 10-30 damage, a character with high DEX like the elf will hit close to 30 more consistently.
Luck (LUC) - Luck affects your chances for a critical hit.
From my understanding retribution automatically casts a spell when you get hit by the enemy. If there is 10% Ice retribution, that means if you get hit, there is a 10% chance that you will automatically shoot an ice spell back at the enemy. I have no clue what determines the damage though.
