>>440274>I think I remember one called "Protect" but had zero clue what it does.
That's the one. Basically what it does is improves your qi shield. When a daoist cultivator takes damage, they lose some qi instead of getting hurt, until their qi runs out. The higher the protect skill, the more damage each point of qi can absorb. Qi also regenerates constantly except when forming golden core
, so if you have a dude with 300 Qi regen and a shield strength of 0.5, he can tank 150 damage per second . If you boost his protection skill and increase the shield strength to 2.0, that jumps to 600 damage per second he can survive indefinitely.
The reason you unequip the artefact is because tribulations expend their qi to nuke everything around them, and when an equipped artefact runs out of qi, because it's been hit, it refills its qi pool from the cultivator's.
