Guild Wars 2

What is on your main weapon? Remember anything that’s an on-proc ability shares a cooldown. That means weapon swap and crit proc sigils share a CD.

Yeah, just make sure that if you are using battle on the OH, you don’t have a proc on the MH, or the proc cooldown will eat your chance to get the 3 stacks of might from battle.

General rule of thumb is that if you want to run geomancy on the Staff, run a stack sigil and geomancy on the MH/OH swap. That way every swap does the geo aoe bleed proc.

In a more generic sense, if you are talking about Spvp, geomancy is really nice, while in WvW, it will go to waste very often unless you spend a lot of time up close and personal. I think Battle and Geo are both cooldowns that are shorter than your swap though, so if you wanted to use both you could (assuming you wanted battle/stack sigil in first set, and geo on your staff). Don’t put them together though, they can’t plan on the same swap set (MH – Battle, OH – Geo = Won’t work)

If I’m reading it right, you are saying what to put on your staff? I wouldn’t put AoE effects on the staff, you rarely will find yourself so close that it would be worthwhile.

And for what Rennoko said, the CDs for on-swap weapons are 9 seconds, so they will always proc on every swap, so long as you are not using another on-proc sigil.
