There are also skills other than crafting skills that cannot fully take advantage of the 15 minutes. I don't see a possibility of altering them. As an example, bards have a delay before they can begin their next barding attempt, taming attempts take some time to actually process.
Which crafting skills are you using Alacrity Scrolls to train with?
The only 1 i would would be imbueing... get it to about 75, then 2 -3 alacrity scrolls. And start burning gear. You can get to 120 fast just by breaking it down that way.
Pre-make enough tools to last you a day, place wood in a bag in your pack totaling 400 stone, place 4 tools in your pack, open menu and select what you want made and hit make max and while things are being made keep replacing wood in bag as need to keep making what ever it is you are making, when a tool wears out use another. You do understand that using these scroll esp for Carp is a waste of gold, buy wood or better yet go chop your own.
Stand next to a secure, in the secure place several tools and several bags, in each bag put as many boards as you can reasonably hold.
Put one bag in your back pack, start the scroll, craft the item required for your skill level, the items will be crafted in the same bag.
When the bag is full, or you run out of boards, or you reach your weight limit (depending on what you're crafting) dump the bag, get the next bag out of the secure, continue.
LOL Just because something exists doesn't mean you have to use it or better yet whining about something you get for free is priceless.
In my experience the Crafting skills are perhaps the second most-efficient in terms of optimal use of Alacrities; especially if you are due for a guaranteed gain from a day or more of inactivity. Only spellcasting skills where you have a spell to cast with a high gain chance are more efficient.
Popps are you seriously complaining about the amount of work you have to do in a "15 minute time period" ?
It really sounds like you wait till after you consume the scroll to even bother to get ready to train the skill, it is called getting prepared before you eat it. It also sounds like you think you should be able to hold everything in your backpack to allow you to do whatever for 15 min. First you must understand the limits of your char and once you understand the limits then you need to stage your work area in preparation for the task. These scrolls have been around for a long time and to you are the first person I have heard complaining about them. Training a Carp is one of the easiest skills to train and the new crafting gump is a great with make max. This forum is really gonna blow up when you get to using tailor and smith scroll but it will really go over the deep end when you eat an imbuing scroll. Maybe you should learn to train the skill before you try using ASs. I am not sure if we have any training skill pages here but I do know that Stratics has a ton of them esp the Crafting ones, maybe you should go find them and read them first.
BUT BUT BUT you mean I have to log off and log in another char to get more stuff OMG HOW UNFAIR that I have to go through all those steps, why can't I just unravel the same thing for 15 min and get 5 points every time, it is so unfair.
