VoC Moon, Spiritual Warfare

I'm just wondering if there is any spiritual warfare that can be done during a void of course moon. It's void all day today, and to be honest, I don't like not being able to do anything. I know rituals are out, but are thoughtforms/vibrating runes/sigils too? I assumed they would not be effective during a void moon, and I know now that I should have asked this question months ago. One should never assume. I realized my mistake just now. It just occurred to me, and I feel like an idiot for not asking much earlier. All these VoC moons, and me not doing a thing :(

Hail Zeus!
