PC on Nightfall Staff upgrades

I've had problems working out how much these upgrades would be worth. They're the following:

9% chance of fast casting
10% chance of fast casting - max stat.

20% chance of fast recharge on staff's attribute (so basically 20% recharge) - max stat.

So does anyone know what these might be/should be worth?

I also have a +14% damage while health is over 50% mod. The +15%/50% mods go for about 15k - is this worth maybe 10k? 5k?

Interesting mods but too early to say. Nightfall insciptions are quite confusing at the moment.

Does anyone else have some ideas about prices?

14^50 is abuot 1-2k. The 15^50 are now about 10k In the last week I have had over a dozen of 15^50. I will not salvage off 14% ones.

The staff mods are fairly common once you get into the higher end area's off chests and drops. I have sold most of those for 5k some just went to vendor after a few minutes of trying. They are really becoming not worth the effort of trying to sell.

I will only salvage off 15^50's. +5 or +5^50 now unless its a mod i want.

If you salvage off everything be ready for a very long time in a zone spamming WTS. Not to mention a full storage and backpacks

1= 9%= merch
10%= 3kish
2= 10kish
