Caster Liz

Chloe already generates a lot of stars in her 6 hit arts cards when her 3rd skill is up (and specially, when maxed). Still, not a bad choice...

Saberlot is better, his second skill will suck all the stars of IM or PC and combine with his own passive stars for massive sure crit turns... or just use Liz stars when his skills are on cooldown...He's an arts crit servant, extra stars are nice to him, they can help each other to bulit their NP gauge.

Some Arts Rider (Georgius/Mordred) to easily absorb her stars, plus bult her Arts chains? Put Hans inside for Crit Up...

Nursery Rhyme s the perfect farm partner, Self Modification can absorb her stars, both have triple arts deck, so they can spam NP chains, and AOE NPs, so using to farm the assassin dailies is nice; with NR as main dmg dealer, Liz as hybrid passive stargen support + secondary dmg dealer.

She is offensive caster with decent AOE damage. However, she won't be so great when put her as support. Also why you want put pair Kuro with her?

Her Buster type NP is somehow a bit uncompatible as Casters in art team. But very good for a Buster chain as pairing with other servants, using skills to send star to them for Critical Buster.. If you are chasing for extreme good Buster farming, then Nightingale and Merlin.
Paired with Jalter is also decent for star sending and utilize Jalter's 2nd skill.
