Lodi shield is another one of those expensive, hard to replace items that also happens to lower agi. Djarn's ring will more than make up for it, but not for fungi or both. It's not like there aren't other items with agi, especially at endgame, it's just annoying having to account for it all until then. But yeah, cha is conveniently cheap and there are other items on top of ones previously mentioned to bump the numbers up higher. Other than jaspers for BP clicks, paladins don't tend to need a lot of bag space.
