Sources of crit for spells?

I'm trying to get a list of sources of spell crit together since I feel like it's generally a high-opportunity cost stat and want to make sure I'm not missing any big sources of it

Sources I'm aware of are:

• Passive tree (Arcane Potency, Annihilation, Doom Cast, Light of Divinity, High Voltage)
• Power Charges
• Support Gems (Increased critical strikes, inspiration)
• Modifier on weapon
• Cluster Jewels
• Watcher's Eye mods
• Ice Golem
• Zealotry
• Bottled Faith
