|Effects||+2-10% mining damage|
Efficient excavation is a skill in the mining skill tree. The skill is in the first tier of the skill tree, and has no requirement to level up. Each point allocated to this skill will increase your mining damage by 2%.
Mining experience is gained by dealing mining damage to a wall with a pickaxe or melee hit (punch). Unbreakable walls, or those the player is not able to damage, will not award experience points. Walls that are broken too slowly will not award any experience.
Each mining skill level increases your mining damage by 1, for up to +100 at level 100. Every fifth level awards a skill point that can be allocated in the mining talent tree. Populating it from the top:
