Its honestly only as hard as you make it. The Anima weapons are "meant" to be done over time (usually 2-3 months on average). If you wanted to get it in 1-2 weeks, yeah, you're gonna have a bad time. I'm taking the very casual route to finishing my Anima and also working 40hrs/5days, so I can relate. I just do a few daily roulettes (not minding if I miss one) to get Esoterics and Poetics, spend my allowances getting Vilekin, and doing the 24-man raids once a week. It's really just become part of the background things I do while playing FFxiv, thats the only way I can make it feel like "non-work".


Edit: I just realized you're talking about the old relic, not the current one. Whoops
