Adept HCT 20% upgrade to a collector staff with HCT 20%

Hi,
I've read a lot about stacking HCT with wand/focus items and this is a great thread on it.

http://www.guildwarsguru.com/forum/s...php?t=10040956

My question is whether two HCT 20% chances on the same item work the same way.

I have a collector staff with HCT Fire 20% and I added an adept staff head with 20% HCT. So the staff has two HCT Fire 20% mods & neither say 'non-stacking'.

Some simple testing of 40 casts showed 20 normal, 18 HCT and 2 QCT (Quarter Cast Speed), so roughly 50%, 45% at HCT and 5% at QCT. This seems to imply that they stack in the same way as two mods on different items, i.e. 32% at HCT and 4% QCT. I'm sure my %'s are off due to the small sample.

Can anyone confirm this?

Thanks

yes, they work exactly the same way as having an HCT on your wand and off hand

It's not that they stack, but the HCT check is run twice regardless of the result of the previous.

For example, using that same staff, you want to cast Meteor Shower. The game runs the first HCT check (which succeeds), so the 5sec cast time is reduced to 2.5sec. Now the second check is done, which also succeeds, so now the cast time is down to 1.25sec.

If either check failed, but the other succeeded, you're still at 2.5 sec for a 5 sec spell. I know this was all explained on a wiki entry somewhere, but I'm not sure where.

That help?

Thanks for the replies - they were very helpful.
