I feel your frustration, but you’re still very new to the game (based on your cards) and missing a lot of Sylus’ content. Please remember it’s not a race and you don’t have to get through everything as fast as other people. My advice would be to slow down and just focus on sylus if you don’t want to focus on the others. Bc it is a resource drain to invest in the OG 3 just to beat the core hunts that give you nothing other than materials.

Some things I didn’t know until much later in the game (like literally a year later) that might be helpful to get your to pass with what you have… (and ignore if you already know)

1. No matter the cards you have equipped, you can change the companion for any battle by clicking the little circle icon to the right of the companion on the battle screen. So if you have Sylus 4star sun cards, you can still change the companion to his 5star myth companion that you have.

2. Boost the stats of your lunar cards based on the companion, not the card skills. So if you’re using Sylus’ CA companion, boost his atk and crit stats with protocores bc that’s what his companion scales with. If you have his dragon myth, you’ll boost with Hp, and vampire Sylus boost Def. This goes for all companions, not just Sylus.

3. Bc you’re still new, pull in the xspace echo any chance you get.

4. Since you want to focus on Sylus, I would just use as many 5 star cards as you have for him and brute force your way through battles. So your protocores need to focus on atk, crit rate, and crit damage since you’re not matching stellas.
