One thing I've found about list construction is that Artifacts aren't generally all that inspiring. They're good, don't get me wrong, but I'm interested in seeing what kinds of new builds we can support with just an artifact. For example:
- Heartseeker lets you keep a ranged hero safe, at a steep cost. Not very dramatic, and the price keeps it from being ubiquitous, but this means you can be sure of getting use out of even the most fragile ranged hero, if that's what you're after.
- Reaping Blade is an ok damage boost, and adds some on-demand high-defense mitigation. Good to have available, but probably not build-defining.
- Fortuna's Dice is a pure fixer. Mostly it's just a flat damage boost, but it also lets ranged heroes guarantee an Accuracy result. Very strong, but not all that interesting .
- Shield of Margath is more along the lines of what I'm thinking! It fundamentally changes the attrition math for melee fights, and so directly enables the "thorns" build. Obviously it needs the right platform (Hawthorne, maybe Kingsbone Kethra), but it's a big deal.
So if you were tasked with introducing a new neutral artifact, what would it be?
