Artifacts

Runestones
Artifacts are crafted using runestones. The cost of crafting your nth artifact is 2^n runestones.

Runestones are earned by killing Epic Bosses and Time Looping.

Runestones earned from Time Looping = (stage - 100) * .05 * numofheroes + (stage - 90) * .05

Each addend is rounded to the nearest whole number.
