Good grief I remember when it took me forever to GM my tamer/mage back in the late 90's 2000. Anyhow, I went to moonglow like you said, and I went from 36.2 to 40.1 in like 2 hours.
Ty.
Good times in that sens not all that much have changed over the years taming is still one of the hardest skills to train in game
Power scrolls are also a new thing that you may not know about
There are 4 different power scrolls 105, 110, 115 and 120 they come from doing champion spawns in felluca what they do is they raise the skill cap of the skill on the powerscroll
So a 115 taming powerscroll raise the skill cap in taming to 115 everybody is at 100 cap to start with
Champion spawns are some of the harder content in game so you probably need to be fully trained and have a good suit and good pets to be able to do them and even so you probably will not be able to do them alone but they are very popular and people have done them for years so there are plenty of people selling powerscrolls on vendors
It is probably easier to hunt for gold and then buy the scrolls you need than to actually go get them yourself (it is random what skill and number you get so if you are looking for a 120 taming you might have to do 1000 spawns to get one)
I have not played all that much the last couple of years and for the last 3 years done almost no trading at all but i can give you the numbers these scrolls use to sell for
Taming 120 3-4 m
taming 115 300-400 k
taming 110 30-40 k
taming 105 do not remember
these numbers are probably outdated but it give you an idea of what people might ask for these scrolls
Also you do not need to use all the powerscrolls if you start with a 120 taming scroll your taming cap is at 120 =max so buy what you can afford and then uppgrade along the way
