Long story short: in an old book, you found some mysterious writing. Unwisely you decided to read it out loud. Turns out it was a spell, that turned you invisible and you have no idea, how to reverse it.

UPDATE:
I've added my dice roller script. Totally forgot about it yesterday, don't how.

==========Dice Roller User Manual==========
To use the script, write !Roll(<value>), or !roll(<value>), where <value> represents a percentage, of how likely you are to succeed in  given task. 

- In addition, you can instead of value include one of the preset keywords, and roll against a random number:
   - 'easy': 66 - 99
   - 'normal': 33 - 66
   -  'hard': 1 - 33
- If you use anything else in the parentheses, you'll be 'punished' by rolling against 1 and if you put nothing in there, you'll be rolling against 50 (coinflip).
- Also putting a number higher then 99 or lower then 1 should lead to rolling against 1.
 - Rolling 1 is always a 'Critical Success' and rolling 100 is always 'Critical Failure'.

You are invisible. Permanently!
