Also note unlike TFT Attributes will not be able to increase. You can increase skill/spell bonuses with experience, but not attributes.
Below is a brief rewrite of experience for consideration:
Heroes & Other Worlds is a game of adventure inspired by Metagaming's classic Melee/Wizard/TFT system combined with inspiration from the Moldvay edited basic game. The rules are easy to learn and use standard six sided dice. The system is simple, sensible and flexible in the spirit of classic role playing games from the early 80's. Become a Hero, Other Worlds await!
