Due to several questions in-game I have decided to add the part of the update log in an info thread itself.
Drop Boost Scrolls:
Improve your chances for loot with this scroll! Redeeming a scroll will give you a 30 minute 15% rare drop boost, making those extra-rare drops more likely during your bossing session. Here are the details:
This applies to any rare monster loot, as well as Raids loot (Chambers of Xeric, as well as the Theatre of Blood).
You will be notified that your scroll helped you in receiving your loot if you do receive any rare loot.
Pet Drop Scroll:
Improve your chances to receive Pets by 25% for 30 minutes!
This applies to all pets, including those found from: Skilling, bossing and mini-games (Such as raids). It also improves your chances when gambling Infernal/Fire capes for pets!
FAQ (applies to both scrolls):
Are these stackable?
The item itself takes up 1 inventory slot per scroll. As for the effect, it depends on your game mode:
Normal players:
You can open as many of these as you’d like, and the timer will increase.
Elite Ironmen/Classic/HCIM:
You can only use 1 scroll every 3 hours. You can have both types of scrolls active simultaneously, though, as the timers are different.
EIM only: You cannot stack scrolls, even if you opened one yesterday and immediately logged out, and tried to open one now to get a full hour of improved drops.
Does the timer go down if you’re AFK?
If you haven’t clicked within the past couple of minutes, your timer will stop going down. It will only go down for active players to avoid wasting bonus time.
Can these scrolls be transferred between accounts?
These scrolls are tradeable, and as for transferring to non-trade accounts, these scrolls can be transferred between accounts the same way that bonds can be by using them on players.
How do I know how much time I have left?
Client timers will show you the time left on your scrolls on-screen.
