Re: Defense charm:
True. But it's really not reliable to get defense charms compared to true sight pot, and they run out super fast.
If you check shop regularly you can have all kinds of goodies given that you have the souls on hand.
And you should check what kind of effects they have, some can be useful.
I also like hoarding my best weapons and feel kinda shitty using nukes on normal enemies, though now i have shanoa i should probably be less of a stickler considering i've stockpiled like 10 weapons in the chest and carry another 5.
My rule of thumb is if I have the materials on hand to craft it, especially the heroine weapons I should be able to use it next, I can keep the essence and scrap to craft it better in base or make it directly in the dungeon if I take the heroine material but with possible worse results in terms of enchantments.
Enchanting accessories with skills is a bit of a trap as you always lose them, so only use them for a boss run, you are always better of keeping your Max Skill Wind Knifer with a bunch of haste enchantments then putting that on accessory.
Although mobility skills can be good on accessories for a boss run.
I also don't really bother with enchant effects beyond 'deal more damage' because big number makes brain feel good (though i do understand that getting stuff like sleep%, stun%, kb% especially are strong).
You can do some intresting builds if you can consistently craft weapons with certain effects and skills.
Like combo Elemental Charge skills or Elemental Damage Multipliers with Elemental AoE weapons.
The Bat Summon you can put Physical Damage on them if you use the summoning consumables.
You have things that spawn things on mobility skills, although that is hard to stack on weapons.
You can get secondary effects on Knockback and other Debuffs.
Basically the more you can consistently craft the same weapon and accumulate their effect the more game breaking it becomes.
So it's important to not waste scraps and essences and do most of your crafting at base where you can guarantee the weapon and good enchantments.
