The Shar-worshipping crazy goth chick is a great character concept. Trouble is, the game seems to throw a lot of great light-related cleric spells and equipment at us, and all the alternatives seem to be bad. From an RP point of view, Shadowheart obviously shouldn’t be wielding a light-emitting mace, wearing radiance armor, and shooting Faerie Fire and Guiding Bolt all over the place. But I can’t find a lore-friendly playstyle that isn’t substantially worse in fights.
Some of the Shar-related equipment, and the Trickery domain subclass perks, seem to point to some sort of melee cleric build exploiting darkness. But the overall effect seems subpar; for starters, clerics can’t cast Darkness, so another party member would need to supply that, which is clunky.
Any suggestions?
Not going to spoil anything but progressing in act 2, depending on your choices you might have something closer to what you are describing.
