Force Skills

The Force system is used in Etrian Odyssey II: Heroes of Lagaard with a revision in Etrian Odyssey 2 Untold: The Fafnir Knight that gets brought forward to Etrian Odyssey Nexus, succeeding the Boost mechanic from Etrian Odyssey for gauge-based super moves.

Etrian Odyssey II: Heroes of Lagaard

Every class has a unique Force skill that can be accessed once their Force meter (located under their in-battle menu) is full. Force caps out at 100 and is typically increased through taking actions in battle.

• Defending, using a skill, taking damage, killing an enemy: +2
• Normal attack: +1
• Fleeing from battle: -5
• Any equipment with a "Force↑" effect adds +5 Force to any action taken in battle.
• Dying in battle causes a character to lose all their Force.

Etrian Odyssey 2 Untold: The Fafnir Knight

This game uses a revised version of the Force system, separating it into Force Boost and Force Break. When a party member has a full Force gauge, they can activate their Force Boost, which is a three-turn state that empowers them in various ways. Triggering Force Boost can be done in addition to the party member's action for the turn. Once the three turns expire, Force Boost ends and the party member's Force gauge is set to zero.

Whenever a party member takes an action in battle their Force gauge increases by a random amount between 5 to 15^{Increment calculations needed}, which can be increased by skills like the Fafnir's Force Mastery. Dying halves the party member's current Force gauge, but dying while Force Boost is active sets their gauge to zero. Resting in town completely fills the party's Force gauges.

While Force Boost is active, the party member can also activate Force Break, even on the same turn they activate Force Boost. The Force Break is typically an extremely strong action, but choosing to use the Force Break disables the Force gauge for the rest of the expedition, rendering them unable to use either until they return to town. While there are methods to restore a broken Force gauge, such methods are incredibly rare. If the party member is unable to execute their Force Break (by being bound, incapacitated, or the battle ending before they can act) they do not lose their Force gauge.

Force Breaks scale with the party member's current level. The three "levels" of Force Break in any Skills page depict the skill's multipliers at level 1, 60, and 99. Between 1 and 60, Force Break scales linearly between the first and second threshold, and then past level 60, it scales between the second and third thresholds (at different increments).

Damage-inflicting Force Breaks receive a reduced bonus multiplier from any Charge Skills. For example, the Fafnir's Force Charge skill at Level 10 normally gives a ×1.60 damage multiplier to any other skill, but instead gives a ×1.30 multiplier to the Ignition Ray Force Break skill.
