Truthbringer

Truthbringer is a Legacy Artifact.
==Obtainment==
Learn the Grand Collection of Two Worlds Fragment manual (obtained from as a random drop from Ancient Cultivators), and craft it with an Artifact Crafting Skill Level of at least 20 to obtain the Incubation item.
Cultivate for 360 years while carrying the artifact incubationXiaWorld.ToilAbsorbLing.OnStepToil to receive the legacy artifact, which can then be claimed, locking the item to that cultivator. Since this dififcult in regular gameplay, the artifact has to be unlocked with the Heaven-Mending Chant Miracle instead. 
It is also possible to use the Meditation Miracles to speed it up, as what counts is the cultivator age spent. For example, using Zen Reflection (1 year spent per 200s, or 1/3rd of a day), it would take 120 days of gameplay. 
==Uses==
The artifact has a relatively low base damage compared to other artifacts, however it compensates by increasing the wielder's Artifact Mastery Skill Level by 10.
