Piercing Wail makes every enemy lose six Strength for the turn, or eight when upgraded. Enfeebling Touch reduces one enemy by eight, or eleven when upgraded. The reduction covers that enemy’s attacks for the turn; it does not permanently lower the damage of later turns.

Strength applies to each hit

Strength changes attack damage per hit. A plain attack showing 8 × 3 with no other damage modifiers becomes 2 × 3 after six Strength loss. That prevents 18 damage. Against a single 24-damage hit, the same reduction prevents six. This is why an apparently modest Strength reduction can outperform a large Block card against repeated attacks.

These examples isolate Strength. Weak, Vulnerable and enemy-specific rules can change the final intent. Damage does not become negative healing when Strength loss exceeds the attack’s damage. Read the updated intent after applying the effect before spending the rest of your defensive hand.

Weak and Strength loss do different jobs

Weak reduces attack damage by 25%; Strength loss subtracts from each hit. Against a large single hit, the percentage reduction can prevent more damage. Against many small hits, subtracting a flat amount from every hit is particularly effective. You can combine the effects when both are available, but the Weak percentage applies to the attack with its Strength changes. Do not add the damage prevented by two separate, unmodified calculations.

Piercing Wail’s all-enemy targeting matters in group encounters. Add the reductions across the enemies that actually intend to attack. Applying it to three enemies that are all buffing does not bank protection for their next attacks. Enfeebling Touch instead lets you choose one attacker; its Ethereal keyword also means leaving it in hand through the end of the turn can remove it from that combat.

Artifact and phase changes

Artifact can block the Strength-loss debuff. Check the enemy’s remaining charges before counting the reduction in your survival calculation. An attack intent that has not fallen is a warning that the intended protection has not taken effect.

Older reports describe Test Subject entering phase two with extra Strength when Enfeebling Touch triggered lethal Sleight of Flesh damage. Stable v0.107.1 explicitly fixed that interaction. It should not be treated as a reason to reject Enfeebling Touch in the current fight.

A phase change can still replace the enemy’s current plan. Recheck its intent and displayed powers after triggering one. Temporary Strength loss is protection for the present attack window; it is not a promise that the next phase will retain the same damage or debuffs.
