Hello question: mithral chain shirt+ armor kilt on a arcana caster that can cast on light armor like a bard for example, does he start to get arcane cast penalty ? does he need medium armor proficiency to use it? What is the max dexterity bonus of it?

1. The mithral chain shirt + kilt combo is going to have the same 10% cast penalty as he'd have without the kilt. (Chain shirt: 20% ACP, Mithral -10%.)
2. He would indeed need Medium proficiency to use it.
3. Max Dex bonus would be +6 (Chain Shirt's +4, Mithral's +2).
