Increase Damage Per Second (DPS) / Quality of Life (QoL) with this one simple trick.
Starting at lvl 90 (need fact check), you can use waking stones to increase the base damage, reduce sp cost, reduce cooldown, or reduce stamina cost on your respective skills. The stones rank from C to A.
Season 4 raids drop them frequently and they usually provide C rank waking stones. You can get B rank and A rank waking stones from certain battles however they are rare.
Simply complete the story quest provided by Dianann in Rocheste magician guild and use the crystal on the specific skill you want.
You can go to Dianann in Rocheste or you can right-click the waking stone and select Skill Awakening > select the skill > select the stone you want to bind to the skill > select Use.
You will need to use Erg Crystals dropped from dungeons in order to awaken the skill or you use Skill awakening delimiters (pulled from gachas and play guide mission stage 6). If you decide to use Erg crystals, each erg used raises the % by 1-3%. Try to make sure you hit the max % so have the highest chance of awakening the skill.
