However, upon looking at the options, I'm not too sure on some details.
First, the tank seems to favor high strength, due to the best shields weighing a ton. However, I've found that strength scaling on weapons tends to be pretty bad, with only a few weapons having better than C scaling. It looks like the heavy weapons are more based on base damage than on scaling. Since I don't know how scaling translates into damage, I can't really make an educated decision here. The Great Club seems the best option, with good strength scaling at a reasonable level of base strength, but I'd appreciate some alternative options, with explanations as to why, so I can better understand the options for heavy weapons.
Second, there's the matter of auxiliary abilities. Faith, bows, and pyromancy. Bows only ask for a bit of dexterity, with the Heavy Crossbow asking for no additional stats at all. 12 Dex gets me the composite bow which scales with strength, although that bow is apparently bad for sniping, which is a downside. I don't know enough about bows to note anything other than that. Can you aim with crossbows as well?
Pyromancy will offer some decent options for only a few points of attunement. Nothing here really strikes my fancy, but I'm not familiar with every spell yet. And while nothing seems to me to be a 'must have', they're still solid options, especially for adding another type of damage (is physical resist a big enough problem in this game that I should have something like Pyromancy to even things out?)
Miracles require the biggest investment, of both Attunement and Faith. But they also provide some nice rewards. When tanking hits, being able to use heal spells between battles will save Estus flasks. 12 Faith and Attunement can let me have Heal, and Force, which can be useful to buy myself some space. The Heal spell may be less useful later on when my vitality starts to climb, though.
This is not a PvP build, just a PvE build. But despite that, I still want to take it 'seriously' and try to be efficient. I'm a sucker for that kind of thing And please, whenever you make a suggestion, please try to explain why in as much detail as possible. Good advice is fine, but the more I understand about why I'm doing something, the more capable I'll be of making my own decisions later on.
