Today I acquired Celestia, Brightest Star of Day. I noticed that using it off-hand it still seemed to make Fiery Detonation and Greater Sunburst quite often. To confirm I tried using it off-hand with a throwing weapon. It does indeed still work, here is my shuriken sunbursting:
And fiery detonating:
There are a few questions I have which someone may have an answer to:
- Does anyone know of a list of these type of off-hand (or other equipment slot) effects that apply to either just your main-hand weapon or to whatever weapons you have equipped?
- Do Greater Sunburst and Fiery Detonation apply to just your main-hand (as in I believe Stunning +10 and double-strike) or to both your main-hand and off-hand (as in Eternal Fire)? I can probably test these depending on the combat log order, though perhaps someone knows.
- Does Greater Sunburst stack, i.e. if I were to wield Celestia in my main-hand another Greater Sunburst weapon in my off-hand, would Greater Sunburst happen twice as often?
On a related note, I tested and Fiery Detonation does not stack with itself:
It does however stack with Freezing Gale:
So if you're making two alchemical weapons, you should make sure they have different tier III properties.
