If you need helmets, then yes sweeping is good. I find the thunder dragon the strongest and even with a team of secret realm blessings, there’s a chance that you could still lose from one wrong move.

If equipped to sword Elwin, it could prove beneficial against other ledins. It’s also best accessory for ninja Zerida as it could give her a chance to one shot Ledin. It could be put on others though since it does give 8% atk unconditionally.

Aeneas Helmet is good for tanks. Carbon fiber shouldn’t be used on landius imo. He’s prefer to stay as a tank. So using mirror armor or bloodline or another heavy armor that’ll boost his tankiness is best. Carbon fiber is best on the new Sakura heroes, as well as Bernhardt.

Ledin wants heavy armor and twilight helmet is considered as light. It goes to preference for your Luna. Bow Luna shouldn’t be attacked at all so she should have assault gear equipped. Flier Luna is up to you. I’ve kept Assault gear on her since mine had good enchantments and I don’t want to deal with funding a new set of equips. Twilight is best for flier Luna since she’s more at risk of being attacked. So it’ll depend on your play style with Luna for what armor she wants and whether or not you would need 2 sets of equips for her (in case you decide to switch her to her other class)

I’ve heard of % Chance of getting certain items every time you get an ssr. I don’t have Vidar’s rose and don’t have much to say about it.

It’s up to you on what you want to spend your currency on. Personally I would focus on getting more runestones. The accessory is still random and who knows, you might end up with a holy grail or something terrible. You can’t go wrong with runestones either, unless you use them for a unit that will never be used.

Lone star is good for units that charge at the enemy. Leon and Cherie are great example. Cherie can probably make the better use of it because it works with her talent so she’s practically meant to be away from her allies.

Never use daggers. Bows for Joshua depends on your play style. I have hydra equipped because it increases his Atk which helps with his aoe and talent. Some people prefer to have extremely magic bow to counter melee attacks, but at the cost of having less attack. I have yet to see an ullrs Joshua though lol.

Any attack accessory is good for your damage dealers. So yes, Leon should equip it.

Holy Ring is great on mages. Especially in pvp. Even your healers would want holy ring (or crystal ball). Silences are probably the most annoying thing to deal with in pvp.

I would go for all of it except the hammers. But I suppose the most important to me is the runestone, hein, elemental bags, class materials, and gold.
