Green Steel Spell Points

[CanuckWisdom]

Im considering crafting another GS accessory and Im just wondering about adding SP onto it.

The +100 SP tier two I believe (for example on a min2 necklace), what does that NOT stack with? All I currently have on is wizardy from another GS item, can I expect them to stack? The language on the planner I use is not entirely clear, are the SP exceptional and stack, or is it just the ability skill + bonus?

Thanks.

Green Steel plain +HP/SP boni stack with everything except itself.

Greensteel HP/SP also won't stack with Dragontouched runes offering the same quantity.
