Combat is officially described as unrestricted by stamina
Cold Symmetry and the Steam store describe Mortal Shell II combat as unrestricted by stamina. That changes the resource question, but it does not mean every action is free of recovery, positioning risk, ammunition, ability conditions, or enemy punishment. Do not translate 'no stamina bar' into 'attack continuously.' A safer interpretation is that the player can choose actions without waiting for a stamina refill, while still reading animation commitment, range, posture, and the next enemy response.
Posture creates a visible combat objective
The official store text says players use multiple tactics to shatter enemy posture and strike critically. Treat posture pressure as a route to an opening, not as a published damage formula. Test which attacks, abilities, or ranged interruptions visibly move the encounter toward a break in the current build. The official material does not publish universal posture values, so this guide avoids exact thresholds and recommends comparing the same target under the same patch.
A critical strike is the conversion step
Breaking posture is useful only if the player recognizes and converts the opening. In practice, prepare before the break: maintain safe positioning, avoid beginning a long recovery at the wrong moment, and know which follow-up the current interface permits. The official description establishes the posture-to-critical relationship but not a single best conversion for every weapon. Record whether the attempted follow-up connects reliably rather than ranking it from an isolated clip.
Shell choice changes the available decisions
The official site and Steam page state that eight lost warriors can be possessed as Shells, each with innate abilities and a story to uncover. That supports a role-based selection framework, not an unsupported tier list. Compare what a Shell lets you do after a mistake, against groups, at range, or during a posture opening. Exact ability values and balance can change, so use current in-game descriptions for numbers and use official pages for the stable high-level system.
Melee and ranged weapons are both upgrade paths
Official store copy explicitly mentions strategic upgrades for melee and ranged weapons. Before spending, identify the problem the upgrade must solve: safe reach, interruption, posture pressure, recovery, or a ranged answer. Then test one step on a familiar route. The official material does not promise that one weapon family dominates. A build is coherent when its Shell, melee option, and ranged option cover different failure cases without relying on an unverified interaction.
A source-safe combat test
Choose one familiar enemy and record the Shell, melee weapon, ranged weapon, patch, and goal. Test a normal punish, a posture-focused sequence, a two-enemy pull, and recovery after one deliberate mistake. Repeat rather than trusting one successful attempt. This produces useful evidence without inventing frames or damage values. Use the Build Planner to save the card and revisit it after an official patch changes targeting, camera, inventory control, or balance.
Separate targeting assistance from combat timing
Patch 86845 added Default, Light, and Off target-steering choices for some player attacks. This option can change facing behavior, so record it whenever a comparison depends on attacks connecting at an angle. It does not rewrite the official posture system or prove that a miss came from frame timing. First repeat the same approach under Default, then Light if more manual control is needed. Use Off only as a reversible diagnostic because the official notes do not recommend it. Keeping steering, camera sensitivity, weapon, and enemy constant prevents a control preference from being mistaken for a balance change.
