The latest Age of Sigmar: Spearhead errata brings several key adjustments to the Sand and Bone set. These changes tighten up unclear interactions and improve overall gameplay flow, especially around terrain and scoring.
To see how the recent errata changes have affected Sand and Bone, be sure to check out the updated Spearhead Tier List.
Below is a breakdown of what has changed and what it means for your games.
Summary of Changes
| Rule Area | Change Summary | Effect |
|---|---|---|
| Terrain | Added clear line-of-sight definition | Easier cover rulings |
| Battleplan (Ossia) | Adds Crypt of Blood to the center regardless | More structured maps |
| Twist: Survivor’s Grief | Prevents replacement unit abuse | Balanced scoring |
| Battle Tactic: Monument of Living Bone | Clarifies target as objective for one turn only | Clearer scoring logic |
Overview
The new Spearhead: Sand and Bone Errata focuses on clarifying how terrain affects attacks, updating the pre-battle sequence for the Ossia realm battlefield, and refining how points are scored in certain Twist and Battle Tactic cards.
While none of these changes completely alter how the set plays, they do have an impact on tactical decision-making, especially around positioning and victory point strategies.
Terrain Rule Clarification
Added rule:
“When a unit is targeted by an attack, if it is impossible to draw a straight line from the closest point on the attacking model’s base to the closest point on a model in the target unit’s base without that line passing over a terrain feature, the target unit is considered to be behind a terrain feature for that attack.”
What this means:
This clarification makes it much easier to determine when a unit benefits from terrain protection. If a straight line cannot be drawn between bases without crossing terrain, the defending unit now clearly gains the advantage of cover.
This reduces arguments and ensures consistent rulings for ranged combat and terrain-heavy maps.
Battleplan: Sand and Bone Update
Old text:
“Then they set up the mystical terrain for that realm battlefield as shown on the deployment maps, if any.”
New text:
“Then, if you are fighting on the Ossia realm battlefield, set up a Crypt of Blood terrain feature in the middle of the battlefield.”
What this means:
Games played on the Ossia battlefield will now always feature a Crypt of Blood placed at the center. This creates a predictable and thematic focal point for both players, encouraging more central clashes and tighter control battles.
Twist Card: Survivor’s Grief
Old rule:
“Each player scores 1 victory point at the end of their turn for each friendly unit that is destroyed or that is a replacement unit.”
New rule:
“Each player scores 1 victory point at the end of their turn for each friendly unit from their Spearhead that has either been destroyed or replaced this battle, not including replacement units.”
What this means:
The original rule could be exploited by recycling replacement units to farm victory points. The update now ensures that only your original Spearhead units count toward scoring. This closes a major loophole and brings the Twist back in line with balanced play.
Battle Tactic: Monument of Living Bone
Old text:
“The target is also treated as an objective.”
New effect:
“The target is also treated as an objective for the rest of the turn.”
This one is a clarification of intent. It removes confusion about how that target interacts with scoring and objective control.
Final Thoughts
This errata doesn’t reinvent Sand and Bone, but it definitely tightens the experience. The biggest win is the terrain rule clarification, which removes a lot of guesswork around line of sight and cover.
The adjustments to Twist and Battleplan cards help prevent exploitative scoring tactics, making matches fairer and more tactical overall.
For players who enjoy Spearhead’s fast-paced, strategic style, these updates bring welcome polish and consistency to one of the most thematic sets so far.
