Easiest solution is to use a tgod, the 85% lightning resist + absorb makes gloams virtually harmless (and beneficial in many cases). Of course this means you cannot wear full tal set any more.
I use a 19% absorb wisp projector on my meteorb with full tal set. It's less safe than tgod, but it avoids the trouble of switching gears.
Kuafu already gave a hint. T-God's will give you 85% res and enough absorb to completely counter it, but it would mean giving up the advantage of full Tal's set if you wear it. You still have to be very careful when a conviction boss is near, of course.
The bolts are very fast and have a very long range, so it will often be too late to avoid them if they have been shot already, in particular if you don't have a very good ping. Running zigzag towards them for melee characters or rectangular to them for others is a good idea.
