Character Path Objectives in Fantasy Strategy/RPG

Hey Everyone

My fantasy board game design is going well and have done a few playtests recently. Each playtest grants me some insight to one or two good ideas or changes that help make the game smoother and well-rounded. Hopefully in 10-20 more playtests (which tend to occur less than once a month), the game will be smoothed out to start working towards the next step, a Kickstarter campaign.

That said, I have a question for you all you other board game aficionados out there, as you all have had great input in the past. Before I get to my question, you will need some background info on my game; I'll try to keep it brief and concise.

My game is a sandbox strategy/RPG. Players create characters that gain training in physical combat (think warrior/knight), archery (self-explanatory), stealth (self-explanatory), and magic, which is broken up into six elements: fire, earth, air, water, light, and shadow. Each training grants one new ability, some passive and some active. Characters travel around a world map, taking on quests, defeating monsters, looting castle ruins, visiting town markets for gear, and visiting elemental temples for their unique blessings. As they complete quests, they gain experience, which is used for additional trainings. To put it simply, it would be similar to a hybrid D&D/Skyrim/Final Fantasy game.

While there are obvious character archetypes (knight, archer, rogue, mage), the game is sandbox in that there are no classes or limitations on trainings. One character may be pure mage and take trainings in all the elements, while another may train in stealth, physical combat, and magic for a unique build blending the features and abilities of the various trainings.

At character creation, characters must take on a Path: Path of the Warrior, Path of the Archer, Path of the Rogue, or Path of the Mage. The Paths do not limit any trainings, items, abilities, etc, but they are meant to help the player learn the function of their chosen archetype easily, as well as ease into the game. (The game is meant to take around 3-4 hours to play... possibly longer, but this is a work in progress.) =P I was thinking that each Path would have 2-3 unique objectives that must be completed sequentially, and as each one was done, the character would gain a couple bonus XP, to help facilitate quicker character progression. (Side Note: Characters can't take on quests until they have completed their chosen Path.)

My question comes from my lack of imagination. I am having trouble coming up with original or interesting Path objectives. I have a good first for each Path, listed below:

Path of the Warrior: Kill a monster with a melee attack.
Path of the Archer: Kill a monster with a ranged attack.
Path of the Rogue: Kill a monster while sneaking.
Path of the Mage: Kill a monster with a spell.

Again, these are the most basic of the objectives, meant to quickly show how that archetype typically functions. I would like 1-2 more objectives for each Path, and for them to be slightly more difficult. A couple examples would be:

Path of the Mage: Kill two monsters with a single spell.
Path of the Rogue: Successfully sneak twice in a single combat with two or more monsters.

The issue with the above examples are they are dependent on specific abilities taken from those available within the training disciplines. It doesn't seem fair to force the players to choose a certain ability to complete a Path objective.

I know this is pretty open-ended, as you could ask a ton of questions before coming up with ideas, but I figured I could answer any questions you needed answered to come up with ideas, would spurt off ideas anyways, or could just give any input or thoughts on the Paths idea, or game in general.

Thank you for reading my article and your thought.
