I can answer this. Chiv is generally used because at lower levels you can be more effective than you could with magery. Also, you're playing a no resist template so Chiv can remove curses, and it also gives you a res for less overall skill points.
I don't really understand taking Chiv at 110 over Magery if you're throwing that many points into it. I also think 120 Vet is fairly useless, and you'd have much more success putting those points into med. In addition, Chiv heals have the smaller range, and you benefit from having magery more because you can gheal from a greater distance and not be put in risk at for example, Melisande.
Use a fair amount of + skill jewels and use something like this... Also use a - mage weapon so you aren't as defenseless. Someone as well mentioned to get more SDI for holy light, but SDI does not affect holy light at all.
120 taming (+30 Jewels)
110 lore
100 vet
120 music
120 disco (+30 Jewels)
110 Mage
80-100 Med Depending on Skill Cap.
I've also ran 4/6 Chiv/Spellweave Tamer without the Disco and it tears stuff up hardcore in groups.
