Hi Awkward, I'm using a Djinn icon as I'm not much of a 2D artist and the Djinn is at least integral to the class identity. I'll try to work towards a better icon set, but its low priority for me.

The blank was an open slot that I didn't have a skill for, the latest update (v.63) added in a new skill, so the trees should now be full and display properly.

Staffs? I did notice I had duplicated the embermage armorset as preparation for custom sorcerer gear, they are now removed from this latest update.

PS. What the reason to implement lot of ordinal staffs?

First what i see with your mod is human hero wil jinn icon (it not too intuitive)
Second, skills. 3rd tab, second line, second skill. looks like it not implemented but place is busy by template. (Check, if working skiil must be there)

Thanks to everyone who has or is playing the Sorcerer. I'm hoping to finish off the skills and tier bonuses, but could use some feedback from you about what is fun, what isn't, what works and what doesn't.

Seeing what builds you're running would help along way on this!
