Boneshaper build: Sustainable summon line

What is this build trying to do?

Prefer repeatable summons, ways to direct or support them, and enough self-sustain to keep the engine operating. Build a useful front line without filling every doorway. Inspect summon focus before spending your command action.

This is a role-based strategy framework. It does not claim to be a verified level-by-level digital card, equipment or perk list. Check the current digital card text before making an irreversible selection.

How do you set up a repeatable turn?

1. Place the first summon where it can reach the approaching enemy.
2. Keep the summoner safe while supporting the units already contributing.
3. Replace a fallen unit only when the replacement will have useful turns before the room ends.

Summon where the next enemy engagement will happen. Keep lanes open so allies can move and the summons can reach their targets. Your own health is part of the engine, so a turn spent stabilizing yourself can protect several future summon turns.

Which cards should you prioritize?

Use a summon package with enough replacements to recover from a bad focus pattern, then reserve support and self-preservation. Bone Dagger is digitally confirmed to summon a skeleton. Flesh Shield is documented in a summon-damage prevention interaction, so inspect it when protecting a valuable unit. Putrid Cloud is not a poison source: recent official notes explicitly remove that incorrect behavior. Choose it for its actual current effect, not a remembered exploit.

Compare a candidate card against the job your current hand cannot accomplish: reaching a useful hex, making the primary attack legal, surviving the next enemy action or recovering a disrupted turn. Avoid upgrading a number while losing the only action that keeps the sequence reliable. Exact level selections remain subject to digital Codex verification.

How should equipment and perks support the plan?

Choose survival equipment based on the summoner’s own incoming attacks and the health spent maintaining the engine. Do not assume an item that enhances your attack also enhances summon attacks. Recovery and movement can be more helpful than increasing the first skeleton’s damage.

Inspect Animate: digital notes confirm its healing applies to the Boneshaper even when a summon draws the modifier. A swarm making many attacks can value reliable self-sustain differently from a single durable summon. Compare that engine value with ordinary deck cleanup.

What should you change when the plan fails?

Putting every unit through a narrow entrance can leave most of your damage idle. Another trap is relying on old Putrid Cloud poison behavior, which the current patch history says was incorrect.

Identify whether the failure was positioning, timing, a resource shortage or a party mismatch before replacing the entire hand. Record a change and test it over another expedition rather than changing several decisions at once.

Which references help with this build?

Start with the Boneshaper class reference, use party composition to assign allies’ roles, and revisit card economy when the party exhausts before completing its objective.

Evidence boundary: Digital starter identity verified; strategy is editorial and tabletop-informed, not a tested 1.0 card list.
