Also make sure you bought all the elixirs in the advent shop for the current event too, they're cheap and help a bit.
Gem gacha is an option but it's not a resource that you will use to gain a lot of elixirs because you'll be using those elixirs to counterbalance all the gems you burned getting the few you'll end up getting. I'm not expecting you to have enough gems to be pulling 100k gems worth a day if you're that new either. I'm rank 125 and even I'm struggling to stay above 1mil gem as I can't make it to every gem quest and it doesn't help more awakenings and final breaks are coming out.
Last case scenario, you can run story mode inbetween events for story materials to exchange in the shop for elixirs.
