It's important to note that some characters weapons, such as Revali's Great Eagle Bow, has a hidden seal at level 25 (in this case, Midair Damage ++) so that might give some builds some direction

I have a star seal that says "Damage to Foes with Status Effects: +13" no idea what is does

Hey there! I know you have a LOT on the go right now, but if you get time, can you add a best weapon build for each type of weapon a character can wield? So, a best build for Link’s two-handed and spear weapon types, and Zelda’s Sheikah slate weapon. Thanks!

First seal pair gives +5 damage. Second seal pair (of not the same as the first) gives an additional +5 for +10 total. I feel like this is better than most seal combinations here.
Information about the different tiers of seals would be nice too.

Where it says "Important!" for the Master Sword that Seals are not removable." The Seals are actually removable after completing "Daily Drills: Rito" and you unlock the "Secret of the Rito Artisans" Hut Upgrade which states "Reward: Gain the Ability to Remove All Seals" in the Blacksmith

I just got Sacred Bow for Zelda from her Amiibo. I can provide images if needed

There is also a soup ladel.

You forgot Wooden Spoon
