Crystal Focus applied to staff with arcane damage

[attila]

Sorry for repeating this, but it seems my previous question seemed buried under other responses and forgotten...

I command-staffed a dragonbone staff to Arcane damage, then applied Crystal Focus to it. What I got back was disappointingly a staff with just +10% arcane damage. So basically the original plain dragonbone staff's +30% arcane damage was reduced to just +10% by the crystal.

However if the original dragonbone staff is dishing out other damage types (e.g.: fire or ice), then the crystal focus will produce an additional +10% arcane damage, while keeping the original +30% damage type.

Is this intended behavior or a bug?

What happens if you set the staff to fire, use the crystal, THEN switch to arcane?

I honestly think its a bug. Why would this powerful arcane crystal diminish the latent powers of my staff?

After Crystal Focus is applied, the staff loses the Command Staff ability.

Which as mentioned by someone else sounds appropriate since the Crystal Focus is an artifact of the Spellblaze.
