Better Instigation

Changes to the files:

QUICKSTART

• Changed terms from Grandmaster to Instigator (thanks for the suggestion Embustero, on our discord).
• Health: Changed the order of the paragraphs for better logic.
• Combat: added which die you have to roll to start the combat (1d12).
• Combat: Fixed a typo with the closing puntuation mark on point 4.

CHARACTER CREATION

• Fixed the text on the white box down at the right, so it wouldn't be repetitive.
