@mikemearls I want to home brew a tower shield into 5e. How would you do it?

When carried, +4 AC but no attack, spells, or using objects, can be put in position, provides cover while carried or in position. https://t.co/bi7lsCtGzp

essentially 2 normal shields if normal shields ac bonus stacked? yeah, with benefit of providing cover, too
