Fortune's Weave uses strategic, turn-based combat. Players command units against enemies and are expected to learn each unit's strengths and weaknesses before directing them. Heroes also have special abilities that can change the result of a battle. Nintendo has not published the full weapon triangle, movement rules, class roster, terrain effects or difficulty settings in the cited material.
The public footage and descriptions confirm the command structure—command units, direct them in a turn-based battle and use the party's abilities—but not every rule behind it. The game should not be treated as a verified copy of a previous Fire Emblem system until Intelligent Systems confirms which returning mechanics are present.
Blaze Arts and the Blaze Gauge
Heroes can use powerful signature moves called Blaze Arts. The confirmed cost is HP: using a Blaze Art reduces the hero's health. Each use fills the Blaze Gauge, and reaching the halfway mark grants a helpful power boost.
The gauge has a risk at full charge. Nintendo says filling it completely causes Burst, which ends the bonuses and cuts the hero's maximum HP in half. That creates a clear resource decision: a player may seek the halfway boost while avoiding a full gauge, or accept the penalty for a different battle plan. The official explanation does not list every Blaze Art, exact HP cost, bonus effect or duration, so no universal use pattern can be recommended yet.
Blessings
Blessings are another confirmed combat support system. Earn a god's favor and that god grants boons that can give an advantage in battle. Leveling a Blessing unlocks more effects, including temporary reductions to damage from enemy attacks.
The available information does not state how favor is earned, how many gods can be followed, whether Blessings are shared across all four stories, or whether their effects change by map. Those are update points for a post-launch systems guide. The confirmed relationship is simple: earn favor, receive a Blessing, level it for additional effects and use those effects during battles.
