Cheat sheets that run it
Tips that save runs
- Fleeting Expertise: efficiency bonuses add together, so both mods count. Fleeting Expertise costs Ability Duration.
- Blind Rage: it adds Ability Strength but raises ability costs, and Streamline pulls the cost back down.
- Energy-hungry casters that spam their abilities: every point of efficiency saves energy on each cast.
- Efficiency bonuses from mods add together, they do not multiply.
- Streamline has max rank 5 and can be traded.
Mistakes that waste runs
- Expecting Streamline to multiply with Fleeting Expertise. The two bonuses add.
- Skipping the Mars Junction reward and buying or farming the mod instead.
