Below is a list of skills and range of legitimate values for a Creator charm. You can choose a Skill #1 and a Skill #2. They cannot be the same Skill though. Use the Search function to filter the skill you are interested in.
If you are using Neset armor set, which gives you x2 and +2 to all skills you have in your Talisman, You may not need max values. This also attracts lesser attention if it is a concern to you.
Example, Tenderiser +4, Expert +9, OOO, is enough activate Weakness Exploit and Critical Eye +3.
