As mentioned in the longer post in the general forum https://www.shroudoftheavatar.com/forum/index.php?threads/my-final-thoughts.174452/ most skills and spells cost the same 100 gold. That is a bit strange, as the spells and skills grow stonger in higher tiers which would be a reason to demand a higher price and we have three different trainers, Basic, Adventurer and Master Trainer, yet all are content to get the same amount for their training? How about a pricing system like this? Basic Trainer 100 gold / skill or spell learned Adventurer Trainer 200 gold Master Trainer 400 gold
I like the current pricing system. New players won’t level their skills by the same levels but will focus on one or two and max them out. Why punish them?
Those gold amounts are so trivial, I don't think it would make sense to make a change here. The act of going out and buying the recipe is the true hindrance. The cost is just a formality. 100 gold or 400 really isn't going to change anything at all. Just a waste of time for the devs.
Little impairment. The Basic Trainers (in the outskirts/starting areas) would remain unchanged and let the player learn a skill or spell for 100 gold so that new starting players would see no difference (if they would even know that, being new starting players). The Adventurer Trainer would demand 200 gold instead of 100 gold, but that can be minimized if a player learns everything possible from the Basic Trainers and bothers the Adventurer Trainer only for those spells/skills that the Basic Trainer does not train. Players will usually first meet an AT in Soltown after they finished Solace Bridge Outskirts and then 200 gold are no problem by e.g. fighting the bandits in Soltown Catacombs or doing the Solace Bridge Outskirts Heirloom quest repeatedly. The Master Trainer demands 400 gold and again - if you did learn every possible spell/skill from the Basics for 100 and every possible spell/skill from the Adventurer Trainer then not too many high level skills /spells remain that cost 400 gold at a time where a player usually has already finished all quests from Solace Bridge Outskirts over Soltown and Ardoris and has no problem earning those armounts. It adds a bit of realism in that you bother the professionals and masters of the trade only if you have to, and learn everything you can from the lower trainer for less money and leave only the peak of spells/skills for the Master Tainer, instead of simply going to the Master Trainer and train every mundane and normal spell/skill with him for the same low 100 gold per skill/spell that the Basic and Adventurer Trainer currently demands. IMO if a player bothers the Master to train lower Tier skills /spells then the Master should either demand his higher fee of 400 or outright refuse to be bothered by that mundane, basic stuff. And it would show that higher spells and skills have more value than the first Tiier the Basic Trainer teaches. Edit: I would not even call it a gold sink because the amount is so low and you pay it only once for learning/unlocking every spell/skill as before.
New players won´t know the difference because the Basic Trainer in the starting areas /outskirts would remain unchanged and demand the same old 100 gold per skill / spell learned. Only after completing Solace Bridge Outskirts and coming to Soltown would a player usually first meet an Adventuring Trainer who would demand 200 gold - and then the player would still have the option to go back to the Basic Trainer to learn every not-yet learned spell or skill for 100 that the Basic T. teaches offers, so that the 200 gold would only be required for those spells/skills that the Basic T. does not teach but only the Adventuring Trainer. That players focus on one or two spells or skills at a time is already there - to get to the next Tier you usually need to level skills to e.g. level 40 before you can even start learning the next Tier. And it´s good to level spells you like because they start to get more powerful the higher you level them. However once players are in Soltown they usually are Adventurer Level 10+ and able to pay the professional Adventurer Trainer 200 instead of 100 gold for learning a new spell/skill, as I wrote before e.g. by fighting the bandits in Soltown Catacombs. When players first NEED a Master Trainer (unlike simply searching one out for a lower level spell/skill) they usually are no longer new players but Adventurer Level 50+ and can pay the Master of their Trade what their tutolage is worth.
The journey I described is the one currently recommended by the game - do all 3 outskirts first and then explore the remaining world. Sure someone else might not do it in that order but that does not mean that to pay +100 gold for a very limited number of skills and spells over a very long time (noone learns all spells/skills) at the same time) would pose a problem. If someone skips the Basic Trainer in Solace Bridge Outskirts and goes directly to the Adventuring Trainer and there would notice that the professional Trainer asks 200 gold instead of the 100 of the Basic Trainer could still go back and learn every available spell from the Basic Trainer (Solace Bridge Outskirts and Soltown are not very distant from each other and SBO offers a repeateble quest so there is some incentive to go back there anyway) to save those 100 - OR simply pay up because gold in the amount of a few 100 is no problem.
Just saw it again: The loading screen of the game lists hints at the bottom. One of them says to get the full beginner experience to do all 3 outskirts areas. No idea where those hints are stored in the files.
