Careful with overpricing the orbs. There are 3 properties that are "random." LRC, damage increase or SDI for one of them. HP regen, Stam regen, mana regen for one of them. HCI or DCI for the third. The lower mana cost is always consistent.
If you get all dexxer-type mods, that is worthwhile. If you get all caster-type mods, that is worthwhile. If you get a mix, those aren't as valuable except to niche templates. Example, my nox mage wants the HCI, but also the mana regen and spell damage increase. If you get those exact three mods, nobody but me will want it.
