Boss souls. What should I do with them?

[eXiledheretic]

So apparently I could use them to get a bunch of souls or use them to enchant weapons.

What are your thoughts on this? Weapon or levels?

Also if anybody has used them for souls, how many do they give you?

I was told to save them in order to create weapons with them later.

[Stoboots]

Save them for later. They are not worth using for SL when you can farm bosses in co-op which give pretty huge rewards for no risk.

[DropnFbombs]

Save them. Do not use them for souls. Infact I would say you absolutely should not use any souls you find; save them for an emergency (except the boss souls, never use them to get souls, use them to get gear). If you want spoilers search for "Darksouls II boss souls". Bet you the items each soul produces is already charted.

I'm saving them. If I learned anything from the first game, it's that I'll regret it when it could be "The Weapon" for NG+.

It's not like they'll riot and disapear for being ignored for a couple of days, lol. What ever souls they end up totaling to be wouldn't be any different than when you get access to make them. Like, if you gain 20k total souls from them, and through out this time till you have access to make them you get 200k souls. Your total will still be 220k, but either 20k earlier or later.

If nothing suits you, you'll just have all those souls to reap in on the spot.

[eXiledheretic]

It is unanimous then. Saving it is!

I found most of the weapons they offer to be pretty lack luster. A couple were worth saving but most are not.

[CountZero]

I don't know, the Last Giant Soul is used to obtain Giant Stone Axe that has a high strength requirement for single wield, crappy scaling (only a D for strength) and slow. There are much better axes in the game.

Yeah, you NEVER want to "spend" boss souls. That would just be stupid.
Keep them until you can trade them in for uber gear.

Boss Soul Weapons[darksouls2.wiki.fextralife.com]

[Panic Fire]

Depends on the weapon just remember boss weapons dmg increases significantly with level ups.

Upgrades weapon physical base power by 30% of initial value per level, increases stat scaling.

Vs normal 10%

So those boss weapons may seem lackluster at first but they end up getting 150% base power when fully leveled up.

There are two merchants that offer stuff for boss souls. One before the last sinner and one before the spider boss but you have to rescue her in the shadded woods first
