Access via Inventory

After completing the Altered Design quest, the Inversion Reinforcer can be accessed by clicking on the icon in the lower left corner of the player's inventory.

Unlock Inversion Reinforcement Effects Using Reinforcement Energy

By spending Reinforcement Energy, players can unlock Inversion Reinforcement Effects that provide buffs and debuffs to their Descendant. In order to unlock subsequent nodes, previous nodes must first be unlocked.

Nodes can be reset at any time on the Inversion Reinforcement screen at no additional cost. This makes it easier to experiment with offsetting the debuffs some nodes provide, and to refine a player's build.

Inversion Reinforcement Effects

Currently, there are 5 types of Reinforcement Effects. They are Hunt, Attribute, Recovery, Survival, and Season. Activating all nodes in the same row will activate that row's Collection Effect, which is located in the rightmost node.

The Inversion Reinforcement Effect will apply to all of the player's Descendants.

Restrictions

There are limitations to the Inversion Reinforcer that can make building a character around it quite tricky. Only a maximum of three Inversion Reinforcement effects can be active at any one time.

Then, two effects on the same line cannot be activated at the same time. For example, in the Hunt tree, you cannot have Biodensity Enhancement and Shield Particle Enhancement enabled at the same time.

How To Progress Inversion Reinforcement

Collect Ironheart Particles

To increase the level of the Inversion Reinforcer, players would have to collect Ironheart Particles. Each region would have a list of objectives and activities that the player would need to complete in hard mode in order to obtain Ironheart Particles.

The player can see how many more Ironheart Particles are needed to level by checking the Inversion Reinforcement screen.
