This is what it looks like to create and edit skills. Everything a character does to something is a skill, even basic attacks (like above). You are given familiar values for rating, variance, and critical bonus. Replicate makes the user spawn that many copies of the skill's effect. Then you can make a skill that attacks enemies randomly 3 times or something (random enemy and random ally are options for targeting). You can put in the applied elements and conditions (if any). If a skill cures a condition/buff, it removes all stacks of it. Finally, you can have a common event run after the basic damage derived statistic is run.

Lots of options aren't needed here as you can add any sort of additional behavior or effect through the derived statistic, or the common event if you'd rather not clutter up your derived calculation.
