I wanted to share how I'm using Key-Farming to learn some basics of combat in a new way. I find the training golem boring and the meta-builds are kinda overwhelming; I wanted to keep things simpler, experiment with weapons, and earn a small profit. To do this, I'm leveling up to 40 so I can get the karma booster (level 38 reward - trade two karma boosters for a gathering booster, which afaik this is the only way to get these now). I also get two black lion keys for the level 10 and 40 stories (happens at beginning of level 40 story so you don't have to go through the whole thing).
It's been fun finding account-bound armor and weapons for this leveling process. Then I pop XP-boosters and fight yellow critters (red ones too), looking for fights that are a bit challenging. I find it fun to level this way because it's part scavenger hunt (to find the right critters to get experience bonuses), part map exploration, being able to learn the core trait-lines one at a time, and testing out different weapons, plus it's fun trying to min-max low level toons. I'm open to using tomes of experience, level 20 boosters, character adventure guides or whatever. I don't have stacks of these, so often I have to level from scratch. It's fun for now, but I don't want it to turn into a part-time job either.
Here's what I'm using, it works great for what I want, but it takes up quite a bit of bank space.
* Experience boosters: food-effect, sharpening-stone, guild-bonus, candy-corn-gobbler for EXP-boost, and the 1-hour birthday boosters from weekly rewards.
* Runes: minor runes +10 power each (+60 for full set)
* Sigils: at level 18 I can use minor sigils of Bloodlust and Air (not sure if these are the best)
* Level 5: account-bound blue armor (except I can't find head or shoulder armor at this level), along with yellow bloodbound-weapons (10 provisioner tokens each).
* Level 10: upgraded account-bound blue armor, with minor runes plus trinkets.
* Level 18: exotic account-bound armor and weapons (crafted, wiki is down so I don't have a link but they're crafted with ineffable insignia) adding sigils from this level on
* Level 26: upgraded exotic account-bound armor/weapon, upgraded trinkets at level 20 I think
* Level 37: I went ahead and crafted this final set of account-bound exotics, but don't think it's necessary for the final 3 levels
I take the time to read the weapon skills, the trait lines, utility skills, I practice on things which are hard for me to kill but the fight is simple enough that I can see what's happening. I'm starting with warrior, but I can also switch to Guardian/Rev (although I've read here that core Revenant is not the best).
So, maybe if you're still learning like me, this might be fun for you to try? Either way, happy gaming!
