Do +0, +1, +2 energy focii drop?

I was thinking of farming Istan just to get a focus swap that is fully mod-able.
If there is no +0,+1, or +2 energy focii, it is relatively pointless as you could just use a normal focus that you don't meet the req for...

if only there was a -energy inscription for shields...

well i know you can get a +1 or +2 in presearing in prohecies, so i would assume you can get it in elona also. I don't think a +0 offhand exhists except for certain sheilds

Here is the GuildWiki page that shows what is a available http://gw.gamewikis.org/wiki/Weapon_modifier

I'm talking about the base, not the inherent.

Going for
No req +0/1/2 energy focus
-Inscription "Ignorance is Bliss" +5 armor , -5 energy
-of Swiftness Halves casting time of spells (Chance: 10%) / Fortitude +30HP

Reason? Not meeting req for a focus results in +3 energy, -5 of that is -2 net.

well theres no focus with only +1 or 2 I think the lowest possible is +3

so you can go with +3 -5 then use a -5sword or axe to hide even more energy.
