This is a typical chaplain cookie cutter build. It got most things right, but like others said, you’d want to max sacrament before aspersion.
For PVP, it’s not as good as some FS because chaplain is totally useless. You aren’t going to run around and melee people with your hammer. It’s essentially a dead class and you are better off with almost any other class. That said, you’ll still be fine since you have the backbone priest 3, cleric 2, pd.
Solo grind and party grind are not going to be a problem in any way.
Your role in group is mostly support. Just go easy on buffs - you don’t want to erase people’s more useful buffs unless there’s a krivis. You can also buy daino scrolls.
Are you priest 2 yet? Most of your damage will come from sacrament and blessing(make sure you upgrade its attribute asap). After you become chaplain, you’ll receive another damage boost.
PD is powerful, but a bit overrated imo. It removes some debuffs for sure, but that doesn’t make you immune to cc like some people claim. Psycho can cc a pd all day. It’s really priest 3 stone skin that gives pd the bad rep.
