 If a quest is a bove 50, it has an additional 10k exp per 100th exp_factor value.
 
-If the `exp_factor` is 100, you ad 10,000 exp, if its 200, you add 20,000. etc.
+If the `exp_factor` is 100, you add 10000 exp, if its 200, you add 20000. etc.
 
 So after the question, you would do:
 
 ```js
 exp = (exp_factor * quest_exp_modifier * (45 + 5 * class_level_1)) / 100;
 
-exp + (exp_factor / 100) * 10000;
+exp = exp + (exp_factor / 100) * 10000;
 ```
 
 Not fully confirmed this, but it has worked for a few 50+ quests I tested against.
