Okay, in game while teleporting or loading a screen you see tips to players. One of them says you should always have resurrection scrolls.
I looked every store in the main city and did not find one that sold rezz scrolls. Yesterday a very rude player called me a failure for not being able to rezz him (which I would understand if I was a priest... but sorcerers cannot rezz hehe).
I thought Merchant sells the regular rez scroll, however I don't use these. The specialty merchant has rez scrolls that cast in half the time. To me half the time is important because it feels like forever with the regular ones. One thing to remember is that there is a 20 minute cool down on a rez scroll, so don't start casting it if the mob is close because if you get interrupted you just wasted that scroll and the dude on the ground has to port or wait 20 minutes.
Resurrection scrolls can be gotten for free from mob drops. Fast Res scrolls can be purchased from the Specialty Store merchants.
I have 3 stacks from mob drops. Don't worry about running out, use them as needed.
Once you activate it, no matter what, do not cancel.
One time me and the archer both tried to res the priest, and we both saw what each other were doing and out of habit canceled. Both scrolls are used, but whats worse is both are now in cool down of 20 minutes. Priest Homepointed XD
Check your AH, res scrolls are insanely cheap on my server... I sell my surplus stacks straight to the NPC.
