Dialyn

Dialyn's signature is far ahead of everything else. It grants up to 27% Daze (not Impact), which scales cleanly with her, and a strong 30% CRIT DMG buff for every damage type, Lighter's signature buff without the element restriction. The real prize is 1.5 Energy Regen per second while off-field: more EX Specials means faster stuns and easier Positive Reviews.

Probably her second-best pick. Its off-field Energy Regen is a step below her signature but still enough to bank the Positive Reviews needed for an Ultimate conversion every stun in most teams. Chaining EX Specials (including ones from Customer Complaint points) keeps its stacks full, so it also works for a Daze build.

Dialyn burns through Energy, so this engine's regen does real work sustaining EX Specials. It is awkward, since spending EX Specials for Daze makes holding high Energy for the Impact bonus difficult, but it is a serviceable filler when Yesterday Calls and Hellfire Gears are unavailable.

Because it grants Daze rather than Impact, it scales nicely with Dialyn's flat Impact from her Core Passive and suits teams that need quick stuns. The total absence of Energy Regen is the catch: good Daze means little if she cannot afford her EX Specials.
