Goto "Potions/Skills" Tab.
At "UsingSkillOption" you will find all of your skills, which have been categorized in FavAttack, GroupAttack, etc.
Skills in FavAttacks will be used if there is only 1 mob and skills in GroupAttack will be used if there are many mobs on the same area.
Just click through the columns and you will find your skill somewhere.
Now after you found your skills select it, in the row next to the skill you can configure, how often the bot shall use the skill, the minimum should be the skill cooldown, since a lower cooldown can cause dc issues. (Every 5 seconds, every minutes, etc.
All Times Are In Seconds).
In the next table, which is called UseSkill2, you can configure more skills which shall be used in the same situation.
That way you can let the bot just spam skills, which almost looks like a normal character for the other players.
Now you may check the box in front of FavAttack(e.g.), afterwards safe your changings.
Don't forget that some skills still are very bugged and let you dc very often, sometimes they just dont make damage. (I mean especially Incar skills)
