Hello, Why not create an enhance level which increase the chances of optimisations and decrease the chances of breaking? The more you enhance, the more you got chances of safe enhance (higher chances of optimisation, less chances of breaking, less chances of reducing the level, less damage to the durability, and less Cron's Stone consume for safe optimisation). Seems fair to me. Plus, once you go further in the game, the stuff you try to enhance became more precious and it became a real pain in the *** to break one... It is only justice to get reward for the work you've done, but enhance seems to be an exception in this game so far. Have a nice game everyone!
