TL DR at the end of post.
I've only recently (duh) found out that attunement swaps are supposed to trigger Weapon Swap Sigils.
Right now they seem to not be working properly (some are not triggered at all, others have conflicting cooldowns).
I want to make here a reference post (if there's none yet; I didn't find it) about weapon swap Sigils - which of them have conflicting cooldowns, which do not work at all, and which are OK.
The other thing that I'm not sure how to test is whether the weapon swap cooldown conflicts with critical proc cooldown (Superior Sigil of Purity and Superior Sigil of Nullification being the most interesting ones).
I am doing the testing with a set of daggers on dummies in Mists.
The testing is done with a dagger in MH and no weapon in OH.
I tracked timings via cooldown timers on attunements, so they're pretty accurate (+-0.5 seconds at worst).
So here's the list:
Sigil of Intelligence - Does not work.
Sigil of Superior Battle - Works. There is a cooldown, something close to 10 seconds.
Sigil of Superior Doom - Does not work.
Sigil of Superior Energy - Works. Cooldown is indeed 9 seconds.
Sigil of Superior Geomancy - Works. Applies 3 stacks of Bleeding. Cooldown is slightly more than 9 seconds, more like 10.
Sigil of Superior Hydromancy - Works. Cooldown is 9 seconds, as the tooltip states.
Sigil of Superior Leeching - Does not work.
MH+OH testing. As a rule of thumb, it does not depend which one is MH or OH.
Sigil of Superior Battle overrides Sigil of Superior Hydromancy
Sigil of Superior Battle overrides Sigil of Superior Geomancy
Sigil of Superior Battle overrides Sigil of Superior Energy
Sigil of Superior Hydromancy overrides Sigil of Superior Geomancy
Sigil of Superior Hydromancy overrides Sigil of Superior Energy
Sigil of Superior Geomancy overrides Sigil of Superior Energy
Testing of crit-proc sigils.
Tested Sigil of Superior Geomancy with Sigil of Superior Strength. Used high critrate build (67%) with multiattacking autoattacks for consistency. Of course, I avoided all alien sources of Might.
Sigil of Superior Strength has no internal cooldown whatsoever (Turns out it actually has, further tests showed about 0.2s cd). It can proc for several crits in a row (as long as the hidden 0.2s cd is ready). I've had up to 6 stacks of Might during testing. Sigil of Superior Geomancy also procs well, even right after Sigil of Superior Strength proc.
HOWEVER, Sigil of Superior Strength DOES NOT proc while Sigil of Superior Geomancy is on cooldown. This is 100% confirmed, I tested it repeatedly many times. It takes exactly 9 seconds after Sigil of Superior Geomancy proc for Sigil of Superior Strength proc to be available again.
Tested Sigil of Superior Geomancy with Superior Sigil of Air. Their cooldowns are SHARED. Thus, Sigil of Superior Geomancy did not proc right after Superior Sigil of Air proc and vice versa.
Most of Sigils "Do something on next hit after weapon swap" work 1 time after you actually equip your weapon from inventory. They dont proc off Attunement Swap, so pretty much useless.
Heavily tested Sigil[s] of Superior Earth with 90% critchance build for consistency:
It has hidden inner cooldown, something close to 0.2 seconds. It never ever procced twice from single cast while spamming Scepter Earth 1. It did reliably proc two times during Scepter Air 1 channel (at the start and at the end).
I suspect all "Proc on crit" Sigils work similarly. Thus, due to inner cooldown it is a bad idea to equip two on-crit proc Sigils at the same time. They will conflict with each other, even if tooltip says they have no cooldown (they still have it hidden 0.2s).
Also noticed a weird bug - Sigil[s] of Superior Earth never ever procced while being slotted into Scepter. It worked fine if slotted into dagger (both mainhand and offhand).
Therefore I recommend slotting all these randomly proccing Sigils into Daggers (or Foci/Staves if you prefer). Or test it to be sure.
Sigils with cooldowns share cooldowns (i.e. Sigil of Superior Geomancy and Superior Sigil of Air).
Sigils with procs but without cooldowns (i.e. Sigil of Superior Strength) effectively have 0 seconds cooldown timer. So they do not proc if they are paired with cooldown-based proc Sigil and the latter's "Sigil cooldown" is still ticking.
Sigils that "proc" but have no cooldown listed (i.e. Sigil[s] of Superior Earth ) have hidden internal cooldown of ~0.2 seconds. So it is suboptimal to equip any two of those as well.
Thus, it is suboptimal to use cooldown-based proc Sigil - whether it is a crit-proc or swap-proc - with any other proc Sigil.
