E1
Zelretch's Apprentice
Why it matters
Damage-focused Eidolon: Allows her to "store" Gem Energy when using her Enhanced Skill and causes her next use of Enhanced Skill to also use that stored amount. High value pick for Main DPS Rin, essentially letting her use the Enhanced Skill every turn.
E2
Dimensional Traveler
Why it matters
Strong but rather uninspiring Eidolon for both of her playstyles, providing a 1.3x independent multiplier increase to all Skill DMG, making it her best support Eidolon, while the additional 30% Skill DMG provides a respectable boost to her own damage.
E4
Red Devil: Triple Speed
Why it matters
Rin Tohsaka gains an additional 70% CRIT DMG from her Talent, resulting in yet another meaningful damage increase.
E6
Nailed It This Time!
Why it matters
Massive boost to her Main DPS playstyle: She gets the classic 20% RES PEN and then gains an Extra Turn after her Ultimate, and 24 Gem Energy, allowing her to immediately use her Enhanced Skill.

Rin turns Skill Point traffic into CRIT DMG for whoever spent it, and her joint follow-up needs Archer on the field, so the last two slots are picked for Skill Point economy.
