i think i need to use green vials to beat the vh bosses consistently
i might have to just take one of each and run...
Edit: ...yeah I don't suppose the gold summon pieces drop on 15 or something? 20 is frustratingly inconsistent, and even doing it 5 times for one summon is going to be a pain.
The fact that not MLBing them is going to fuck me over long-term too doesn't really help...
Possibly. The one thing VH has over H is more drops at the very least. Don't expect to MLB a summon this event, but you should be able to LB it two times. I was about rank 40 when I was working on Clow (the light summon in my summon list), and I wasn't able to MLB her. I do still have mats for the next time she comes around, and they do come around again.
It's best to just focus on getting basic setups going until you get stronger. And the key to getting stronger is mainly getting a weapon pool going. Summons help, don't get me wrong, but if you have a decent weapon pool for a foundation, your overall strength will increase. Don't worry too much about getting a single element pool and actually just get weapons. SSR weapons would be nice, but SR weapons aren't bad either once you get a few of them MLB'd and max level.
Just to give an idea, this is what I'm using against the earth summon.
Also don't forget about your job. If your team is lacking a healer, be the healer. As vanilla a setup as it is, dark fencer is great for survival and offense.
