Critical Rate

tldr; about 360

These are the CF values at which FL reaches 100% crit rate in extreme tier dungeons. When using the skill advancement for TS, TS gains bonus crit rate to also reach 100% at these values. When using the skill advancement for FL, TS isn't the highest priority skill, so it doesn't matter if it drops below 100%.

There is no hard set means to reach these numbers; however, not all sources are created equal. Any source that, when changed to power from CF, has a ratio of 2:1 is a good source of CF. Also, remember to activate intimidation while checking how much CF you have, as intimidation gives an additional 34.

Good sources include: vyrsks (including crit substats on pristine versions), innerwear, jewelry etchings, 8 CF roll on circlet, 6 CF roll on brooch & belt, gear infusions, and food. Food and vyrsks in particular are cheap and flexible sources of crit that can be swapped to complement your healer.

Honorable mention: crit necklace. Using a crit necklace instead of power can be a good head start on getting crit when starting out. At max gear the difference between optimizing with a crit necklace vs a power necklace is 2 power. Objectively, a power necklace is better, but it is just 2 power.

Lastly, as said before, this goal is for extreme tier dungeons, lower tiers have lower crit resists. Tests have not been done to find the exact crit cap for FL in lower tiers, however it's not very important while gearing up (if FL crit rate >90%, good enough), and hardly worth the effort when you outgear said tiers.
