Cast on ignite

I have 170 spirit unspended, spell says 60 spirit needed. And when im trying to set it on it says not enough spirit. I disabled everythin and still not working

Noticing that ALL "Cast on ____" Gems do not work on Set 2 weapons. They will only work on set 1 weapons. This most certainly seems like a bug.

In fact, it SOMETIMES works. It also only sometimes works with specific gems, like curse gems do not work if I have Cast on Freeze activated on my second weapon slot.

Unsure what is happening, its a pretty janky interaction.

I'm having this same issue. I have 60/60 spirit and it still wont let me enable it. I removed everything and even got my spirit to 160/160 and still wont let me enable it.

Having the same issue with cast on ignite, fix please?

Okay so the issue for me was that I didn't have any spells slotted into the slots for Cast of ignite....Once I put a spell in it, it let me enable it. Game should tell you that instead of saying not enough spirit.

Same problem. When slotting the skill gem and activating (with and without a slotted 'spell', Spirit does not reduce from total of 96. Icon shades dark. Then when hovering icon with mouse, says "Disabled: not enough Spirit" - even though it costs 60 Spirit and I have 96. Also tried "Elemental Invocation" which is also broken. This skill will only show charges with "Solar Orb" but will not show charges slotting "Flame Wall" or "Spark". I've already burned 3 Spirit Skill Gems trying to find a way around this bug.
