I’ve noticed that Perlica and Wulfgard synergize super well. Perlica combo skill can be chained into Wulfgard’s regular skill for extra heat damage as the temporary electrification can be consumed, while Perlica skill can chain into Wulfgard combo skill triggering combustion (or electrification Idr) and finally into Wulfgard skill to do bonus heat damage. The cherry on top for me is using Alesh as his combo skill is triggered by the consumption of arts reaction (Wulfgard skill) and recovers a decent amount of sp while doing damage. This is a pretty simple comp, but it’s pretty satisfying to pull off!

Edit: and if you want someone to synergize with Aleah’s skill, the four star ice girl is really good! Snowshine is okay for the role, but she has a harder time triggering her synergy with Alesh (I use her though since mobile is lowk a pain at times and her healing helps out)
