Attack-healing spells (e.g., vampiric touch) are not healing

when you add a spell like vampiric touch from the list, it only has the attack field filled in even though it also heals. The field for healing is empty because it depends on the result of the attack cast. Is it possible (without API) to make the heal amount appear along with the attack roll?

Hi Marcin,  Which game system and which character sheet are you using? If you don't know please supply a screenshot of the character sheet.

If it's for D&D 5E, I just manually divide the damage by 2 (rounding up), as the spell describes. D&D involves a lot of math; this is one of the easy ones. :D The touch of your shadow-wreathed hand can siphon life force from others to heal your wounds. Make a melee spell attack⁠ against a creature within your reach. On a hit, the target takes 3d6 necrotic damage, and you regain hit points⁠ equal to half the amount of necrotic damage dealt. Until the spell ends, you can make the attack⁠ again on each of your turns as an action. At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
