I've been frequently running out of Slimes because of how much leveling has to be done to make these GURs from SR and R pieces, so several months ago I started leveling HN cards and using them as substitutes.

1. As mentioned in this page already, you can feed a lv 40 HN to make a lv 27 Slime. This is useful if you want to quickly level stuff and have been stocking up on lv 40 HNs like I have, and suddenly acquired a lot of slimes.

2. For SRs, feed 3 lv 40 HNs with a double xp arcana (ie use Arcana Blessing). You can also reduce it to 2 lv 40 HNs with Blessing + Training

3. For HSRs, feed 3 lv 40 HNs with Blessing + Training

4. For URs, feed 6 lv 40 HNs with Blessing + Training

HN-leveling strategies: I put auto-skill or "confirm to receive reward" HNs on my Skill Unleash x Buff team, such as Huang Long, Chocolatier, and 2x Jean. I rarely ever die with such a team; maybe 2 times per event. There are many qualified HNs such as Adventurer (super super common), Grave Keeper, Bandit (and her TO, Idol), Merchant, Teacher, Gnome, Lilliput, Boots Cat, Elementalist (create from Archer x Dryad)....

For AW I can use a simple GUR crit (Oracle Ascendant) with a UR/SR team buffer, 2 HNs who have any type of skill, and Fortuna. When Fortuna can be awakened, this strategy is going to be pretty damn fast!
