Invention - Literally gets half xp from lamps
Archaeology - You can't get most of the rewards from the skill unless you actually train it
Necromancy - You have to use the skill in combat, at bosses, and do rituals to get your armor and half of your abilities.
This means that the last skill you could TRULY lamp your way through came out in 2013. Do you think it's by design or coincidence?
External link →I can only speak for Archaeology and Necromancy as they were the ones I had designed but the answer is 50/50 between coincidence and on purpose. Coincidence that MTX is primarily XP focused, not that these skills are designed to be "anti-MTX" and on purpose that XP isn't the sole factor.
As others have already pointed out, the skill design for Arch/Necro includes a lot of content that cannot be achieved by just leveling the skill. Having multiple ways to advance through the skill other than just XP makes it more interesting, allows you to do content you may actually enjoy but may not like the sound of and rewards you for trying out all aspects. If I'm asked to work on the next skill I'm sure that I'll look to take more feedback and apply a better version of this for next time.
